Output during faults (analog output during a fault)
It is possible for you to define the type of measured value output
during a fault. The following are possible:
Hold: The last value measured prior to the fault is output for the
duration of the fault.
Actual: The measured value is continuously updated during the
fault.
Zero: see following table:
