Setting the measuring range
DANGER DANGER
An incorrectly calibrated level electrode is a danger to plant safety.
Before bringing the level controller into service, set the active measuring range of the
connected level electrode by calibrating the lower and upper bounds.
For your measurement of the fill level, set the lower bound (0% calibration value) and upper bound
(100% calibration value) of the measuring range of the connected level electrode. This will give you
the necessary active measuring range as a percentage of the boiler level.
You can determine these values for the connected level electrode by performing calibration.
Setting the measuring range for the NRGT 26-2 level transmitter
When connecting the NRGT 26-2 level transmitter, you need to set the upper and lower
bounds of the measuring range on the transmitter.
