Sample measurement

4.2.1

pH measurement

Be sure the electrode has been calibrated before measurement. After rinsing,

Place the pH electrode in the sample.

Press to start the pH measurement, when the endpoint has been reached, the current
measurement is finished.
Note: If the signal is not stable all the time, it is recommended to use manual endpoint mode to
avoid bad repeatability.
4.2.2

mV and Rel.mV measurement

Press to shift to
measurement to perform mV or Rel.mV measurement.
If the meter is connected to an ORP electrode, the mV result is the value of Oxidation-Reduction
Potential value; also called Redox value.
4.3

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.
Note: STARTER 5000 accepts NTC 30 kΩ temperature sensor. For ATC (Auto Temperature
Compensation) or MTC (Manual Temperature Compensation), the Temperature Compensation
only corrects for the change in the output of the electrode, not for the change in the actual solution.
That means the meter corrects the signal (mV) from the pH electrodes to get a more accurate pH
value according to the real temperature.
