Касио протрек prg 270 инструкция

1. Make sure the watch is in the Timekeeping Mode or any one of the sensor modes.

• The sensor modes are: Digital Compass Mode, Barometer/ Thermometer Mode, and Altimeter Mode.

1. Place the watch on a fl at surface. If you are wearing the watch, make sure that your wrist is horizontal (in relation to the horizon).
2. Point the 12 o’clock position of the watch in the direction whose reading you want to take.
3. Press C to start.

• COMP will appear in the upper display to indicate that a digital compass operation is in progress.
• About one second after you press C, pointers (three graphic segments for north, one graphic segment each for south, east, and west) will appear on the display to indicate north, south, east, and west. Direction will also be indicated by literal direction indicators and by a direction angle.

Note

• If the four pointers (north, south, east, west) and the direction indicating letters do not appear on the display when you press C, it could mean that the watch is displaying bearing memory information. If this happens, press E to delete the current bearing memory contents. For more information, see «Using Bearing Memory».
• To return to the Timekeeping Mode, press D. Pressing D will return to the Timekeeping Mode even is a reading operation is in progress.

Digital Compass Readings

• When you press C to start digital compass reading operation, COMP will initially appear on the display to indicate that a digital compass operation is in progress.
• After the first reading is obtained, the watch will continue to take digital compass readings automatically each second for up to 60 seconds. After that, the reading operation will stop automatically.
• The direction indicator and angle value will show — — — to indicate that digital compass readings are complete.
• The auto light switch is disabled during the 60 seconds that digital compass readings are being taken.
• The following table shows the meanings of each of the direction abbreviations that appear on the display.

Direction	Meaning	Direction	Meaning	Direction	Meaning	Direction	Meaning
N	North	NNE	Northnortheast	NE	Northeast	ENE	Eastnortheast
E	East	ESE	Eastsoutheast	SE	Southeast	SSE	Southsoutheast
S	South	SSW	Southsouthwest	SW	Southwest	WSW	Westsouthwest
W	West	WNW	Westnorthwest	NW	Northwest	NNW	Northnorthwest

• The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is horizontal (in relation to the horizon). If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 304 to 326 degrees.
• Note that taking a direction reading while the watch is not horizontal (in relation to the horizon) can result in large direction reading error.
• You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
• Any ongoing direction reading operation is paused temporarily while the watch is performing an alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned on (by pressing L). The direction reading operation resumes for its remaining duration after the operation that caused it to pause is finished.
• See «Digital Compass Precautions» for important information about taking direction readings.

Calibrating the Bearing Sensor

You should calibrate the bearing sensor whenever you feel that the direction readings being produced by the watch are off. You can use any one of two different bearing sensor calibration methods: bidirectional calibration or magnetic declination correction.

• Bidirectional Calibration
  Bidirectional calibration calibrates the bearing sensor in relation to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed to magnetic force. This type of calibration should be used if the watch becomes magnetized for any reason.
• To ensure correct direction readings by this watch, be sure to perform bidirectional calibration before using it. The watch may produce incorrect direction readings if you do not perform bidirectional calibration.
• Magnetic Declination Correction
  With magnetic declination correction, you input a magnetic declination angle (difference between magnetic north and true north), which allows the watch to indicate true north. You can perform this procedure when the magnetic declination angle is indicated on the map you are using. Note that you can input the declination angle in whole degree units only, so you may need to round off the value specifi ed on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6° input 8°, for 7.5° you can input 7° or 8°.

Precautions about bidirectional calibration

• You can use any two opposing directions for bidirectional calibration. You must, however, make sure that they are 180 degrees opposite each other. Remember that if you perform the procedure incorrectly, you will get wrong bearing sensor readings.
• Do not move the watch while calibration of either direction is in progress.
• You should perform bidirectional calibration in an environment that is the same as that where you plan to be taking direction readings. If you plan to take direction readings in an open field, for example, calibrate in an open field.

Using Bearing Memory

Bearing Memory lets you temporarily store and display a direction reading so you can use it as a reference as you take subsequent digital compass readings. The Bearing Memory screen displays the direction angle for the stored reading, along with a pointer that indicates the stored reading.
When you take digital compass readings while the Bearing Memory screen is displayed, the direction angle of the current digital compass reading (as read from the 12 o’clock position of the watch) and the stored Bearing Memory direction reading will both be shown.

To store a direction angle reading in Bearing Memory

1. Press C to start a digital compass reading operation.

• This will take an initial reading and then take readings every second for 60 seconds.
• If a bearing memory direction angle value is already displayed, it means that there is a reading already stored in Bearing Memory. If this happens, press E to clear the Bearing Memory reading and exit the bearing memory screen before performing the above step.

1. During the 60 seconds that digital compass readings are being taken, press E to store the current reading in Bearing Memory

• The Bearing Memory direction angle flashes for about one second as it is stored in Bearing Memory. After that, the Bearing Memory screen (which shows the bearing memory direction angle and pointer) will appear, and a new 60-second direction reading operation will start.
• You can press C at any time while the Bearing Memory screen is displayed, to start a new 60-second direction reading operation. Doing so will display the direction angle for the direction that the 12 o’clock position of the watch is pointed. The direction angle of the current reading will disappear from the display after the 60-second direction reading operation is complete.
• During the first 60 seconds after you display the Bearing Memory screen or during a 60-second direction reading operation you triggered by pressing C while the Bearing Memory screen is on the display, the direction stored in memory is indicated by a Bearing Memory pointer.
• Pressing E while the Bearing Memory screen is displayed will clear the reading currently in Bearing Memory and start a new 60-second direction reading operation.

Using the Digital Compass While Mountain Climbing or Hiking

This section provides three practical applications for using the watch’s built-in digital compass.

• Setting a map and finding your current location Having an idea of your current location is important when mountain climbing or hiking. To do this, you need to «set the map», which means to align the map so the directions indicated on it are aligned with the actual directions of your location. Basically what you are doing is aligning north on the map with north as indicated by the watch.
• Finding the bearing to an objective
• Determining the direction angle to an objective on a map and heading in that direction

To set a map and find your current location

1. With the watch on your wrist, position it so the face is horizontal.
2. While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.

• The reading will appear on the display after about one second.

1. Rotate the map without moving the watch so the northerly direction indicated on the map matches north as indicated by the watch.

• If the watch is configured to indicate magnetic north, align the map’s magnetic north with the watch indication. If the watch has been configured with a declination to correct to true north, align the map’s true north with the watch indication. For details, see «Calibrating the Bearing Sensor».
• This will position the map in accordance with your current location.

1. Determine your location as you check the geographic contours around you.

To find the bearing to an objective

1. With the watch on your wrist, position it so the face is horizontal.
2. Set the map so its northerly indication is aligned with north as indicated by the watch, and determine your current location.

• See «To set a map and find your current location» for information about how to perform the above step.
  1. Next, set the map so the direction you want to travel on the map is pointed straight in front of you.
  2. While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.

  

  • The reading will appear on the display after about one second.

    1. Still holding the map in front of you, turn your body until north as indicated by the watch and the northerly direction on the map are aligned.

    • This will position the map in accordance with your current location, so the bearing to your objective is straight ahead of you.

To determine the direction angle to an objective on a map and head in that direction (Bearing Memory)

1. Set the map so its northerly indication is aligned with north as indicated by the watch, and determine your current location.

• See «To set a map and find your current location» for information about how to perform the above step.

1. As shown in the illustration to the left, change your position so you (and the 12 o’clock position of the watch) are pointed in the direction of objective, while keeping the northerly direction indicated on the map aligned with north as indicated by the watch.

• If you find it difficult to perform the above step while keeping everything aligned, first move into the correct position (12 o’clock position of the watch pointed at the objective) without worrying about the orientation of the map. Next, perform step 1 again to set the map.

1. While in the Timekeeping Mode or in any of the sensor modes, press C to take a compass reading.
2. While direction angle readings are in progress, press E to record the currently displayed direction in Bearing Memory.

• The direction angle value and pointer stored in Bearing Memory will remain on the display for about 60 seconds.
• To re-display the Bearing Memory direction angle value and Bearing Memory pointer, press C.
• See «Using Bearing Memory» for more information.

  1. Now you can advance while monitoring the Bearing Memory pointer to ensure that it remains in the 12 o’clock position.

  • Pressing E while the Bearing Memory direction angle value and Bearing Memory pointer are on the display will clear the Bearing Memory data you saved in step 3 and save the current direction reading in Bearing Memory.

Note

• When mountain climbing or hiking, conditions or geographic contours may make it impossible for you to advance in a straight line. If this happens, return to step 1 and save a new direction to the objective.

Digital Compass Precautions Magnetic North and True North

The northerly direction can be expressed either as magnetic north or true north, which are different from each other. Also, it is important to keep in mind that magnetic north moves over time.

• Magnetic north is the north that is indicated by the needle of a compass.
• True north, which is the location of the North Pole of the Earth’s axis, is the north that is normally indicated on maps.
• The difference between magnetic north and true north is called the «declination». The closer you get to the North Pole, the greater the declination angle.

Location

• Taking a direction reading when you are near a source of strong magnetism can cause large errors in readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.).
• Accurate direction readings are impossible while in a train, boat, air plane, etc.
• Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures picks up magnetism from appliances, etc.

Storage

• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of this, you should store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal computers, washing machines, freezers, etc.).
• Whenever you suspect that the watch may have become magnetized, perform the procedure under «To perform bidirectional calibration».

Specifying Temperature, Barometric Pressure, and Altitude Display Units

Use the procedure below to specify the temperature, barometric pressure, and altitude display units to be used in the Barometer/Thermometer Mode and the Altimeter Mode.

• When TYO (Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (m), the barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings cannot be changed.

To specify temperature, barometric pressure, and altitude display units

1. In the Timekeeping Mode, hold down E for at least two seconds. First, SET Hold will flash on the display, and CITY will be displayed in the upper display. After that, the currently selected city code and city name will scroll across the upper display. Keep E depressed until the scrolling starts.
2. Press D as many times as necessary until UNIT appears on the display.

• See the sequence in step 2 of the procedure under «To change the current time and date settings» for information about how to scroll through setting screens.

To specify this unit:	Press this key:	To toggle between these settings:
Altitude	A	m (meters) and ft (feet)
Barometric Pressure	B	hPa (hectopascals) and inHg (inches of mercury)
Temperature	C	°C (Celsius) and °F (Fahrenheit)

1. After all of the settings are the way you want, press E twice to exit the setting screen.

Taking Barometric Pressure and Temperature Readings

This watch uses a pressure sensor to measure air pressure (barometric pressure) and a temperature sensor to measure temperature.

To take barometric pressure and temperature readings
While in the Timekeeping Mode or in any of the sensor modes, press B to take barometric pressure and temperature readings.

• BARO will appear on the display, indicating that barometric pressure and temperature reading are in progress. The results will appear on the display after about one second.
• After you press B, the watch will take readings every five seconds for the first three minutes, and then every two minutes after that.

Note

• Press D to return to the Timekeeping Mode.
• The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about 1 hour after entering the Barometer/Thermometer Mode.

Barometric Pressure

• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).
• The displayed barometric pressure value changes to — — — if a measured barometric pressure falls outside the range of 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg). The barometric pressure value will reappear as soon as the measured barometric pressure is within the allowable range.

Temperature

• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to — — — °C (or °F) if a measured temperature falls outside the range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear as soon as the measured temperature is within the allowable range.

Display Units

You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value. See «To specify temperature, barometric pressure, and altitude display units».

Barometric Pressure Graph

Barometric pressure indicates changes in the atmosphere. By monitoring these changes you can predict the weather with reasonable accuracy. This watch takes barometric pressure reading automatically every two hours. Readings are used to produce barometric pressure graph and barometric pressure differential pointer readings.

Reading the Barometric Pressure Graph

The barometric pressure graph shows a chronological history of pressure readings.

• When display of the barometric change indicator is disabled, the graph shows the results of up to 21 barometric pressure readings (42 hours).
• When display of the barometric change indicator is enabled, the graph shows the results of up to 11 barometric pressure readings (22 hours).

• The horizontal axis of the graph represents time, with each dot standing for two hours. The rightmost dot represents the most recent reading.
• The vertical axis of the graph represents barometric pressure, with each dot standing for the relative difference between its reading and that of the dots next to it. Each dot represents 1 hPa.

The following shows how to interpret the data that appears on the barometric pressure graph.

Rising barometric pressure indicates that upcoming weather will improve. Falling barometric pressure indicates that upcoming weather will deteriorate.

Note

• If there are sudden changes in weather or temperature, the graph line of past reading may run off the top or bottom of the display. The entire graph will become visible once barometric conditions stabilize.
• The following conditions cause the barometric pressure reading to be skipped, with the corresponding point on the barometric pressure graph being left blank.
• Barometric reading that is out of range (260 hPa to 1,100 hPa or 7.65 inHg to 32.45 inHg)
  • Sensor malfunction

Barometric Pressure Differential Pointer

This pointer indicates the relative difference between the most recent barometric pressure reading indicated on the barometric pressure graph, and the current barometric pressure value displayed in the Barometer/Thermometer Mode.

Reading Barometric Pressure Differential Pointer

Pressure differential is indicated in the range of ±10 hPa, in 1-hPa units.

• The nearby screen shot, for example, shows what the pointer would indicate when the calculated pressure differential is approximately – 5 hPa (approximately – 0.15 inHg).
• Barometric pressure is calculated and displayed using hPa as the standard. The barometric pressure differential also can be read in inHg units as shown in the illustration (1 hPa 0.03 inHg).

Barometric Pressure Change Indications

Your watch analyzes past barometric pressure readings and uses a barometric pressure change indicator to inform you about changes in pressure. If it determines there has been a significant change in pressure, it will beep and all of the graphic segments ( ) around the periphery of the face will flash as a barometric pressure change alert. This means you could start taking barometric pressure readings after reaching a lodge or camp area, and then check the watch the next morning for changes in pressure, and plan you day’s activities accordingly. Note that you can enable or disable display of the barometric pressure change indicator as desired.
Reading the Barometric Pressure Change Indicator

• The barometric pressure change indicator is not displayed if there has been no noteworthy change in barometric pressure.

• To ensure proper results, take barometric readings under conditions where the altitude remains constant.

Example

• In a lodge or campground
• On the ocean

• A change in altitude causes a change in barometric pressure. Because of this, correct readings are impossible. Do not take readings while ascending or descending a mountain, etc.

Enabling or Disabling Display of the Barometric Pressure Change Indicator

You can enable or disable display of the barometric pressure change indicator as desired. When display of the indicator is enabled, the watch will take a barometric pressure reading every two minutes, regardless of the mode it is in.

• When BARO is shown on the display, it means that barometric pressure change indicator display is enabled.
• When BARO is not on the display, it means that barometric pressure change indicator display is disabled.

To enable or disable the barometric pressure change alert
In the Barometer/Thermometer Mode, hold down B for at least two seconds. Keep B depressed until the current setting (INFO Hold ON or INFO Hold OFF) starts to flash on the display.

• If barometric pressure change indicator display is currently enabled, BARO will also appear in the upper display. BARO will not appear if display is currently disabled.
• Note that barometric pressure change indicator display will turn off automatically 24 hours after you turn it on or battery power goes low.
• Note that barometric pressure change indicator display cannot be enabled while the watch’s battery is low.

Pressure Sensor and Temperature Sensor Calibration

The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally require no further adjustment. If you notice serious errors in the pressure readings and temperature readings produced by the watch, you can calibrate the sensor to correct the errors.

• Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before performing the calibration procedure, compare the readings produced by the watch with those of another reliable and accurate barometer.
• Incorrectly calibrating the temperature sensor can result in incorrect readings. Carefully read the following before doing anything.
• Compare the readings produced by the watch with those of another reliable and accurate thermometer.
• If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the temperature of the watch time to stabilize.

To calibrate the pressure sensor and the temperature sensor

Barometer and Thermometer Precautions

• The pressure sensor built into this watch measures changes in air pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in offi cial weather prediction or reporting applications.
• Sudden temperature changes can affect pressure sensor readings. Because of this, there may be some error in the readings produced by the watch.
• Temperature reading are affected by your body temperature, direct sunlight, and moisture. To achieve a more accurate temperature reading, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the surrounding temperature.
