[Operating mode] [Current]
When using "Current" operating mode, the metering quantity is determined by the strength
of an incoming standard signal. For fixed current ranges are available for selection (0-20,
4-20, 20-0, 20-4 mA). The fifth selection option of "Variable" allows you to freely select the
values for the minimum and maximum current limit.
Depending on the selected current range, the left current value determines the minimum
metering quantity and the right current value determines the maximum metering quantity.
The minimum and maximum metering quantities can then be freely selected in a second
step.
