Displays In Case Of Overrange/Error During Measurement - YOKOGAWA WT200 User Manual

2.3 Displays in case of Overrange/Error during
Measurement
IM 253421-01E
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.
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 (see section 4.1, "Selecting the Measurement
Mode").
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 is changed and the contents of the display
changes, the display will indicate as follows.
