ProMinent DULCOMETER D1Cb - Zero Point Calibration (Standard Signal)

During the calibration, the DULCOMETER
®
D1Cb / D1Cc sets the control outputs to "0".
Exception: a basic load or a manual control value has been set. This remains active. The
mA standard signal outputs are frozen. The measured value frozen at the start of calibra‐
tion 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.

The slope in the calibration menu is given as an mA value. This value should be
regarded as the mA/selected measuring unit.
