17.4 Exceeding the measurement range
A measurement range exceedance
·exists when at least one of the three voltage or
current measurement inputs are outside of the
threshold values for the metering range.
·appears as long as it continues and cannot be
acknowledged.
An arrow “upward” marks the respective phase in
which the measurement range exceedance exists.
The unit “V” for voltage and “A” for current
shows whether the measurement range
exceedance exists in the voltage circuit or
current path.
A = current path
V = voltage circuit
Phase (L1/L2/L3)

range exceedance.
Threshold values for the measurement range
exceedance:
I = 7 A
