2.3 Displays in case of Overrange / Error during
Measurement
Overrange display
Overrange occurs when the measured voltage or current exceeds 140% of the rated
measurement range. In that case the range will automatically be increased, however up to 140%
of the maximum range. When this level is exceeded, the overrange display wil appear, which
looks as follows.
Computation over display
When the computed value becomes too high during the computation process, the following
display will appear.
Peak over display
When the sampled data (instantaneous voltage or instantaneous current) exceed approx. 300%
of the measurement range, the “V over” or “A over” indicators at the front panel will light up.
V OVER
A OVER
Note
The “V over” and “A over” indicators at the front panel will light up in case of overrange or peak-over of
any signal which is input to the elements.
Display in case the measurement value is too small
In case either the measured voltage or measured current drops below 0.5% of the measurement
range, the display will indicate as follows. This is only in case the measurement mode is RMS
or V MEAN.
Function Display
V(voltage)
A(current) displays zero
var(reactive power)
PF(power factor)
deg(phase angle)
Interruption during measurement
If the measurement range, or function/element is changed and the contents of the display
changes, the display will indicate as follows.
