In this manual, a Warning identifies conditions and actions that pose hazards to the user. A Caution identifies conditions and actions that may damage the Meter or the equipment under test.

Electrical symbols used on the Meter and in this manual are explained in Table 1.

To avoid possible electric shock or personal injury, follow these guidelines:

• Use this Meter only as specified in this manual or the protection provided by the Meter might be impaired.
• Do not use the Meter if it is damaged. Before you use the Meter, inspect the case. Look for cracks or missing plastic. Pay particular attention to the insulation surrounding the connectors.
• Make sure the battery door is closed and latched before operating the Meter.
• Replace the battery as soon as the battery indicator () appears.
• Remove test leads from the Meter before opening the battery door.
• Inspect the test leads for damaged insulation or exposed metal. Check the test leads for continuity. Replace damaged test leads before you use the Meter.
• Do not apply more than the rated voltage, as marked on the Meter, between the terminals or between any terminal and earth ground.
• Never operate the Meter with the cover removed or the case open.
• Use caution when working with voltages above 30 V ac rms, 42 V ac peak, or 60 V dc. These voltages pose a shock hazard.
• Use only the replacement fuses specified by the manual.
• Use the proper terminals, function, and range for measurements.
• Avoid working alone.
• When measuring current, turn off circuit power before connecting the Meter in the circuit. Remember to place the Meter in series with the circuit.
• When making electrical connections, connect the common test lead before connecting the live test lead; when disconnecting, disconnect the live test lead before disconnecting the common test lead.
• Do not use the Meter if it operates abnormally. Protection may be impaired. When in doubt, have the Meter serviced.
• Do not operate the Meter around explosive gas, vapor, or dust.
• Use only a single 9 V battery, properly installed in the Meter case, to power the Meter.
• When servicing the Meter, use only specified replacement parts.
• When using probes, keep fingers behind the finger guards on the probes.
• Do not use the Low Pass Filter option to verify the presence of hazardous voltages. Voltages greater than what is indicated may be present. First, make a voltage measurement without the filter to detect the possible presence of hazardous voltage. Then select the filter function.

To avoid possible damage to the Meter or to the equipment under test, follow these guidelines:

• Disconnect circuit power and discharge all highvoltage capacitors before testing resistance, continuity, diodes, or capacitance.
• Use the proper terminals, function, and range for all measurements.
• Before measuring current, check the Meter’s fuses.

Main Options

Power-Up Options

Holding a button down while turning the Meter on activates a power-up option. Table 4 includes the power-up options.

Automatic Power-Off

The Meter automatically turns off if you do not turn the rotary switch or press a button for 30 minutes. If MIN MAX Recording is enabled, the Meter will not power off. To disable automatic power-off, refer to Table 4.

Input Alert™ Feature

If a test lead is plugged into the mA/μA or A terminal, but the rotary switch is not set to the correct current position, the beeper warns you by making a chirping sound and the display flashes ««. This warning is intended to stop you from attempting to measure voltage, continuity, resistance, capacitance, or diode values when the leads are plugged into a current terminal.

Placing the probes across (in parallel with) a powered circuit when a lead is plugged into a current terminal can damage the circuit you are testing and blow the Meter’s fuse. This can happen because the resistance through the Meter’s current terminals is very low, so the Meter acts like a short circuit.

Low Pass Filter (87)

The 87 is equipped with an ac low pass filter. When measuring ac voltage or ac frequency, press to activate the low pass filter mode (). The Meter continues measuring in the chosen ac mode, but now the signal diverts through a filter that blocks unwanted voltages above 1 kHz, refer to Figure 2. The lower frequency voltages pass with reduced accuracy to the measurement below 1 kHz. The low pass filter can improve measurement performance on composite sine waves that are typically generated by inverters and variable frequency motor drives.

To avoid possible electric shock or personal injury, do not use the Low Pass Filter option to verify the presence of hazardous voltages. Voltages greater than what is indicated may be present. First, make a voltage measurement without the filter to detect the possible presence of hazardous voltage. Then select the filter function.

Note
In Low Pass Mode, the Meter goes to manual mode. Select ranges by pressing the RANGE button. Autoranging is not available in Low Pass Mode.

Bar Graph

The analog bar graph functions like the needle on an analog meter, but without the overshoot. The bar graph updates 40 times per second. Because the graph responds 10 times faster than the digital display, it is useful for making peak and null adjustments and observing rapidly changing inputs. The graph is not shown for capacitance, frequency counter functions, temperature, or peak min max.

The number of lit segments indicates the measured value and is relative to the full-scale value of the selected range.

In the 60 V range, for example, the major divisions on the scale represent 0, 15, 30, 45, and 60 V. An input of -30 V lights the negative sign and the segments up to the middle of the scale.

The bar graph also has a zoom function, as described under «Zoom

Mode» in the Users Manual located on the 80 Series V User Manuals CD.

Table 6. MIN MAX Functions

Button	MIN MAX Function
	Enter MIN MAX recording mode. The Meter is locked in the range displayed before you entered MIN MAX mode. (Select the desired measurement function and range before entering MIN MAX.) The Meter beeps each time a new minimum or maximum value is recorded.
(while in MIN MAX mode)	Step through maximum (MAX), minimum (MIN), and average (AVG) and present values.
PEAK MIN MAX	Model 87 only: Select 100 ms or 250 μs response time. (The 250 μs response time is indicated by the display.) Stored values are erased. The present and AVG (average) values are not available when 250 μs is selected.
	Stop recording without erasing stored values. Press again to resume recording.
(hold for 1 second)	Exit MIN MAX mode. Stored values are erased. The Meter stays in the selected range.

AutoHOLD Mode

To avoid electrical shock or personal injury, do not use AutoHOLD mode to determine that circuits are without power. The AutoHOLD mode will not capture unstable or noisy readings.

The AutoHOLD mode captures the present reading on the display. When a new, stable reading is detected, the Meter beeps and displays the new reading. To enter or exit AutoHOLD mode, press .

Relative Mode

Selecting relative mode ( ) causes the Meter to zero the display and store the present reading as the reference for subsequent measurements. The Meter is locked into the range selected when you pressed . Press again to exit this mode.

In relative mode, the reading shown is always the difference between the present reading and the stored reference value. For example, if the stored reference value is 15.00 V and the present reading is 14.10 V, the display shows -0.90 V.

Maintenance

To avoid electrical shock or personal injury, repairs or servicing not covered in this manual should be performed only by qualified personnel as described in the 80 Series V Service Information.

General Maintenance

Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents.

Fuse Test

If a test lead is plugged into the mA/μA or A terminal and the rotary switch is turned to a non-current function, the Meter chirps and flashes «» if the fuse associated with that current terminal is good. If the Meter does not chirp or flash ««, the fuse is bad and must be replaced.

To avoid electrical shock or personal injury, remove the test leads and any input signals before replacing the battery or fuses. To prevent damage or injury, install ONLY specified replacement fuses with the amperage, voltage, and speed ratings shown in Replacement Parts in the Users Manual located on the 80 Series V User Manual CD.
