Conductivity Calibration
Pocket conductivity tester allows 1 point calibration. To ensure accurate measurement, we recommend that calibrating the meter regularly.
The tester acceptable calibration ranges from 10 to 18mS/cm (COMT-040-001), 1000 to 1800 µS/cm (COMT-030-001) and 100 to 180 µS/cm
(COMT-020-001). Make sure that you use fresh conductivity standard solution during the calibration. DO NOT reuse calibration solution as it
may be contaminated and affect the calibration and accuracy of measurement.
1.
Rinse the conductivity electrode with distilled water , then rinse with a small
amount of standard solution.
2.
Place the electrode into the standard solution (e.g., 12.88mS/cm), stir the tester
gently. Make sure there are no air bubble trapped in the slot of the sensor.
3.
Press and hold the
Cal
key, the tester enters the calibration mode.
4.
Press the
or
key to set the calibration value. Ensure the displayed value
matches your
calibration standard.
Press
or
key once, the setting value will gradually increase or decrease. Press
and hold the
or
key, the setting value will quickly increase or decrease.
5.
Press the
Meas
key, the calibration value will automatically flash 3 times. The tester
returns to the measurement mode. Calibration is completed.
Exit the calibration
During the calibration process, if you want to exit the calibration mode, DO NOT press the
Meas
key in the step 5. Press the
or
key
until the display shows “

“, then press
the
Meas
key to exit.
