General information
You can measure the following variables:
z
pH value [ ]
z
ORP [mV]
Warning
When a grounded PC is connected, measurements cannot be
performed in grounded media as incorrect values would result.
The USB-A (Device) is not galvanically isolated.
Temperature
measurement
For reproducible pH measurements, it is essential to measure the
temperature of the test sample.
You have the following possibilities to measure the temperature:
z
Automatic measurement of the temperature by the temperature
sensor (NTC30 or Pt1000) integrated in electrode.
z
Manual determination and input of the temperature.
The meter recognizes whether a suitable sensor is connected and
automatically switches on the temperature measurement.
The display of the temperature indicates the active temperature
measuring mode:

Manual
1
Connect a pH or ORP electrode to the meter.
The pH measuring window is displayed.
2
If necessary, select the pH or mV display with
<M>
.
3
Adjust the temperature of the solutions and measure the
current temperature if the measurement is made without a
temperature sensor.
4
Calibrate or check the meter with the combination electrode.
