5.2
pH / mV measurement
Note:
The default settings of the meter are:
displayed unit = pH
temperature unit = °C
manual temperature compensation (when the probe is not connected)
automatic power off deactivated
sampling time of the data logger = 2 seconds
CAUTION:
When first using the probe along with the meter, urgently calibrate before starting with the
measurement.
pH measurement (manual temperature compensation):
1.Switch on the device.
2.Select the
“PH“ measurement mode.
3.Put the plug of the probe into the BNC socket (16).
4.Adapt the temperature manually to the temperature of the solution to be measured
5.Hold the handle of the probe and dip the complete probe head into the solution.
6.Stir slightly.
7.The display will show the pH value and the set temperature value.
pH measurement (automatic temperature compensation - ATC):
1. Switch on the device.
2.
Select the “PH“ measurement mode.
3. Insert the plug of the probe into the BNC socket (16).
4. Insert the plug of the temperature probe into the temperature socket (13).
5. Hold the handles of the probes and dip the complete probe heads into the solution.
6. Stir slightly.
7. The display will show the pH value and the measured temperature value.
Note:
When the pH probe is not in use, the probe head must be in the protective bottle.
