Measuring relative mV
This pH meter can measure relative potential difference by shifting the
measured potential to zero. (A potential without compensation is called
absolute mV.)
1.
Press the CAL key in the mV Instantaneous Value Measurement
mode.
REL is displayed under mV and the current reading value
becomes the offset potential used for compensation, and the
meter will display the relative mV instantaneous value.
2.
Press the CAL key again.
The meter returns to the absolute mV display.
Potential compensation during relative mV Measurement does not affect the
displayed pH value.
For how to check the status of the ORP electrode, refer to “
