General information
You can measure the following parameters:
pH value [ ]
ORP [mV]
Attention
When a grounded PC is connected, measurements cannot be per-
formed 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 tem-
perature of the test sample.
You have the following options to measure the temperature:
Automatic measurement of the temperature by the temperature sen-
sor (NTC30 or Pt1000) integrated in electrode.
Measurement by an external temperature sensor.
Manual determination and input of the temperature.
The measuring instrument recognizes whether a suitable sensor is
connected and automatically switches on the temperature measure-
ment.
The display of the temperature indicates the active temperature mea-
suring mode:

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 cur-
rent temperature if the measurement is made without a temper-
ature sensor.
