sor, and confirm the selection with the "OK" button. Then re-select the type of sensor ac-
tually connected and confirm. The measure point will thus be set back again to the
standard setting of 4 mA = 0 % of the measuring range and 20 mA = 100 % of the measuring
range.
Attention: The measure point should be locked during this adjustment [to prevent an alarm
from being triggered].
NOTE: During this calibration the measuring point must be inhibit [alarm rejection].
NOTE: No adjustments on the MAI module are either necessary or possible for active sensors.
Calibration with a Variable Power Source
One person is required for this procedure. The following steps are to be performed:
- Lock the measure point in question in the “Setup/Measure points” menu to prevent an alarm
from being triggered.
- Then detach the cable connections of the sensor to the MAT module.
- Connect the variable power source to the MAT module as follows:
NOTE: MAT module terminal 1: + pole of the power source [signal]
MAT module terminal 4: – pole of the power source [GND]
