CALIBRATION
function group:
Calibration for ORP
mV
Calibration ORP mV Only for A1 = ORP (mV).
The measuring transmitter has a calibrated mV display range. An
absolute mV value with a single buffer solution (adjustment of
measuring chain offset) is set. Here, a buffer solution is used,
preferably with 225 or 475 mV.
The maximum permitted calibration
offset is ±100 mV.
C21
Enter the mV value
belonging to the
ORP buffer used
Current measured value
1500 ... 1500 mV
In the case of symmetrical
measuring operation, the potential
matching pin must also be immersed
in the buffer.
