Calibration Of The Zero Point Of The Standard Signal General - ProMinent DULCOMETER D1Cb Series Instructions For Assembly And Use

Measured Variables and Operating Menus for the Standard Signal General
During calibration, the DULCOMETER
this is if a basic load or a manual actuating variable has been set. This remains active. The mA standard
signal outputs are frozen. The reading frozen at the start of calibration is suggested as a value. This
value can be set using the arrow keys. Calibration is only possible if the value is ≥ 2 % of the measuring
range of the sensor or the measuring device.
