Calibration / Sample measurement
Note
- To ensure accurate pH or ion concentration readings, you should perform a calibration regularly.
- We recommend the use of a temperature sensor or an electrode with a built-in temperature probe.
- For ion measurements, or some cases in pH measurements, you can use the MTC mode. You should
then keep all buffers or standard solutions and sample solutions at the same set temperature.

Sample measurement

4.5.1 Performing a pH measurement

Place the electrode in the sample and press Read to start the measurement: the decimal point blinks.
The display shows the pH of the sample. The automatic endpoint A is the default setting of the meter.
Select the automatic, manual or timed endpointing method in the menu under "2. Set meas." in "1. EP
Format".
To manually endpoint a measurement press Read, the display freezes and appears.
If the timed endpointing method is selected, the display freezes automatically after the set time has elapsed
and appears.
Note
For stability criterion of automatic endpoint algorithm (A) see Section 4.6.

4.5.2 Performing a mV/rel. mV measurement

To change to mV mode press Mode repeatedly until the mV or rel. mV unit is shown.
To perform a mV measurement, follow the same procedure as for pH measurement.

4.5.3 Performing an ion measurement

To change to ion measurement mode press Mode repeatedly until the preset unit for ion measurement is
shown.
To perform an ion measurement, follow the same procedure as for pH measurement.
