Self-Diagnosis information

How to fix

Wrong pH calibration solution, which

exceeds the recognizable range of

the meter.

1. Check if calibration solution is correct

2. Check if probe is damaged.

3. Check if there is any air bubble in the

glass bulb sensor

Is pressed before measurement

is stable ( appears and stays)

Wait for the smile icon to appear and

stay, then press

* If you find any air bubble in the glass bulb of the pH sensor, simply shake the probe for a few times

to remove it. The existence of an air bubble in the glass bulb will significantly decrease the accuracy

of measurement.

* The 1st point calibration must be 7.00 pH. Perform the 2nd point calibration (4.00 pH) immediately

after the 1st point. Do NOT turn off the meter before you conduct 2nd point calibration. If the meter is

turned off after 1st point calibration, users will need to restart the calibration process with the 7.00 pH

and the 4.00 pH following after. Calibrating directly in pH 4.00 after turning meter off and back on will

cause Er1.
