1.4 Function and Operation of the CAL Screen
The CAL screen has 2 functions and allows you to check the stability of readings.
● Stability: Only pH and ION calibration
You can check the change in the indicated value by seeing the stability always displayed
under the indicated value in the digital display. The stability value is a deviation between
the maximum and minimum values in the last 10 seconds.
For example, you will make a good pH calibration during the stability value is 0.002 or less,
though it depends on measurement environment.
● Graph display
