Connection check
Check if measurement results comply with given limits.
Measurement will be marked with OK sign ( ) if
measurement results are within following limits:
Voltage: 90% ÷ 110% of nominal voltage
Current: 10% ÷ 110% of nominal current (Current clamp
range)
Frequency: 42.5 ÷ 57.5 Hz for 50Hz and 51 ÷ 69 Hz for
60Hz system frequency
U-
I Phase angle: ±90
0
Voltage and current sequence: 1
– 2 – 3
Each measurement, which is not within those limits, will
be market with Fail sign ( ).
