Measurement and Calibration

For better accuracy, frequent calibration of the meter is recommended. In

addition, the instrument must be recalibrated:

• When high accuracy is required.

• At least once a month.

Measurement

Press the ON/OFF button to turn the meter ON. Place the probe to the

desired solution. The conductivity value, automatically compensated for

temperature, will be shown on the LCD.

The measured temperature will be shown on the secondary LCD.

Note: Before taking any measurement make sure the meter has been

calibrated.

Calibration Procedure

• Press CAL button to enter calibration mode from measurement mode.

• The meter will enter the calibration mode, displaying «mS/cm 12.88

USE» with CAL tag blinking.

1. Pour 2″ (5 cm) of standard solution into a container.

2. Place the probe in calibration solution. The probe tip should be centered

in the solution and submersed 1.18″ (3 cm). The meter will automatically

recognize the solution.

3. If the solution is not recognized or is out of the accepted range «—- Err»

is displayed.

4. If the calibration solution is recognized «REC» is displayed until the

reading is stable and the calibration is accepted.

• After acceptance, the «Stor» message is displayed and meter returns to

measurement mode.

Clear Calibration

Place meter in calibration mode. Press ON/OFF and «Clr» is displayed. The

meter will now be at default calibration.

Error messages

During user calibration, if the reading is out of the accepted range, the meter

will display «—- Err».i.e. 20.00 mS/cm blinking means the limit of the

measured value is out of range.

If the measured temperature is higher than 50.0 ºC or lower than 0.0 ºC, the

50.0 ºC or 0.0 ºC temperature value will blink on the LCD in measure mode.

Care and Maintenance

To obtain the highest accuracy for measurement it is important to follow

these tips:

• Calibration is only as good as the solution being used. The calibration

solution values change over time. Fresh solution should be used for each

calibration.

• The probe should be rinsed with purified water each time before placing

in calibration solution or sample to be tested.

Battery Replacement

The meter features a low battery indicator. When the battery is running low

(under 10%), the battery indicator will blink on the LCD. When the battery

is discharged «dEAd bAtt» will be displayed on the LCD for 2 seconds and

the meter will turn off.

To change the CR2032 Li-ion battery, turn the battery cover located on the

back of the meter counterclockwise to unlock. Remove cover and replace with

new battery + side facing up.

Note: Batteries should only be replaced in a safe area using the

battery type specified in this instruction manual. Old batteries should

be disposed in accordance with local regulations.

Recommendations for Users

Before using Hanna Instruments products, make sure that they are entirely

suitable for your specific application and for the environment in which they

are used. Any variation introduced by the user to the supplied equipment

may degrade the meter’ s performance. Avoid touching the electrode area.

To avoid damages or burns, do not put the meter in microwave oven. For

yours and the meter’s safety do not use or store the meter in hazardous

environments.

INSTRUCTION MANUAL

DiST 4

HI98304

EC Tester

Тестеры серии DiST представляют собой прочные и надежные карманные тестеры для получения быстрых и точных показаний электрической проводимости. Серия тестеров DiST® широко используется для мониторинга электрической проводимости питьевой воды, в процессах водоподготовки, обратном осмосе, градирнях, сточных водах, лабораториях, сельском хозяйстве, аквакультуре и аквариумах, гидропонике и полиграфической промышленности. Эти тестеры имеют неокисляемый амперометрический графитовый электрод, обеспечивающий лучшую воспроизводимость при измерениях. Амперометрическое измерение электрической проводимости основано на применении закона Ома, I = V / R, где R зависит от расстояния между двумя электродами и величины их поверхности. Окисление электродов изменяют и расстояние, и величину поверхности, что влияет на точность измерений. Неокисляемые графитовые электроды тестеров DiSTs обеспечивают оптимальную поверхность для получения точных и надежных результатов. Калибровка автоматическая.

OPERATION:

• Remove the protective cap.

• Turn the DiST
