Calibrating redox transmitters and checking connected components

In principle, the process used for checking a redox transmitter is similar to the process used for checking
a pH transmitter – as described on page 10.
Depending on the measuring span of the redox transmitter to be calibrated, set values between 7 pH
and 0 pH on the simulator's pH selection switch. Please refer to the redox potential table below for se-
lecting the correct mV value.
Example:
The measuring span of the redox transmitter is 0 to 100 mV.
Zero point adjustment in the case of switch position 7 pH = 0.00 mV 2 mV.
