INPUT CURRENT Displays the input current according to the current set to the corresponding channel.

Adjusts the displayed input current with an factor.
SET OFFSET
Default value: 0

Decides how other members react if they try to read an input current value while the input
current card is in the function test. As the value of the input current in the function test is not
based on any measurements other members reading this value probably have to be informed
about this special situation. There are three settings: Hold, Active and Transfer.
HOLD
Another reading member does not use the current read value but uses the last value before the
output current card was in the function test mode.
ACTIVE
Another reading member uses the current value even if the output current card is in the function
test mode.
TRANSFER The reading member uses an own substitute value for its own output value.
