The calibrator is now set for the module CALC and it preset the last used calculation type for this
module (in this case the last used calculation type was ChA+ChB).

Press the button indicated with “R” in the picture above to select another calculation type.

Figure 44

– Types of calculation

Here you can find:

CHA + CHB

channel 4 or C displays the total value of the values displayed on channel A and B

CHA - CHB

channel 4 displays the difference value of the values displayed on channel A and B

Cell Load

channel 4 or D4 displays the ratio mV/V of the load cells

CHA+CHB and CHA-CHB functions can be used only if channel A and B are set with the same
values: same engineering unit, same number of digits, no channel assigned with error indication.
Otherwise the channel 4 will be displayed as:
