The settings of CT and/or VT
are not correct and therefore the
measurement exceeds the maximum
admissible value, or is the result
of calculations with at least one
measurement in the status EEEE
The analyzer is not used within the
expected range and therefore the
measurement exceeds the maximum
admissible value, or is the result
of calculations with at least one

on and the set interval for calculating
the average power values (default:
15 min) has not yet elapsed
The value entered is out of range
