Sample measurement

4.2.1

pH measurement

Place the electrode in the sample, stir for 10 seconds, and wait 30-60 seconds.

Press button-

Follow the same procedure as for pH measurement to perform a mV measurement.


Temperature measurement

For better accuracy, we recommend to use either a built-in or a separate temperature electrode.
If a temperature electrode is used, ATC and the sample temperature are displayed.

If the meter does not detect a temperature electrode, it automatically switches to the manual

temperature compensation mode and MTC appears. MTC temperature should be set. (See
