4.6 pH value
4.6.1 General information
You can measure the following variables:
z
pH value [ ]
z
Sensor voltage [mV]
Note
The sensor connection and the USB-B (device) interface are galvani-
cally isolated. This facilitates interference-free measurements also in
the following cases:
z
Measurement in grounded test samples
z
Measurement with several sensors connected to one Multi 3430 in
one test sample
Temperature
measurement
For reproducible pH measurements, it is essential to measure the tem-
perature of the test sample.
IDS sensors measure the temperature with a temperature sensor inte-
grated in the IDS sensor.
Preparatory activities Perform the following preparatory activities when you want to measure:
1 Connect the IDS pH sensor to the meter.
The pH measuring window is displayed.
2 If necessary, select the measured parameter with <M> .
3 If necessary, calibrate or check the IDS pH sensor.
