Chapter 13 Specifications
(13) RMS voltage (Urms)
Measurement method AC+DC True RMS type
IEC61000-4-30 compliant: 10 cycles (50 Hz) o
r 12 cycles (60 Hz) (approx. 200 ms)
During 400 Hz measurement, calculated f
rom 80 cycles (approx. 200 ms)
When set to 3P3W3M/3P4W/3P4W2.5E, the phase voltage/lin
e voltage setting is applied to the
RMS voltage Urms.
Includes Zero-display range.
Displayed item RMS voltage for each channel and AVG (average) RMS voltage for multiple channels
(for more information,see "13.8 Calculation Formula" (p.231)
)
Measurement range 600.00 V
Measurement accuracy When the measurement frequency is set to 50 Hz/60 Hz
With input of 10 V to 660 V: ±0.1% of the nominal voltage; defined for a nominal input voltage
(U
din) of 100 V or greater.
With input outside the range of 10 V to 660 V or a nominal input voltage (Udin) of less than 100 V:
±0.2%
rdg. ±0.08% f.s.
When the measurement frequency is set to 400 Hz
±0.2% rdg.±0.16% f.s.
Event threshold The upper and lower limits can be separately set within the range of 0 to 780 V (lower limit < upper
limit) (value before setting VT ratio)
When set to 3P3W3M/3P4W/3P4W2.5E, the phase voltage/line voltage setting is applied.
Sense Set from 0 V to 600 V.
Event IN Start of the approx. 200 ms aggregation during which the reading exceeded the upper limit or fallen
below the lower limit
Event OUT Start of the approx. 200 ms aggregation during which the reading was less than upper limit minus
hysteresis after being greater than the upper limit or was greater than lower limit plus hysteresis
after being less than the lower limit
Multiple-phase system treatment Separate by channel
Saved waveforms Event waveforms
(14) Voltage DC value (Udc)
Measurement method Average value during approx. 200 ms aggregation synchronized with the reference channel (CH4 only)
Includes Zero-display range.
Displayed item Voltage DC value
Measurement range 600.00 V
Measurement accuracy ±0.3% rdg.±0.08% f.s.
Event threshold 0 V to 1200 V
The difference between the positive and negative waveform p
eak values in the 200 ms aggrega-
tion is compared to the threshold to generate DC fluctuation events.
Event IN Start of the 200 ms aggregation in which the threshold was exceeded
Event OUT Start of the first 200 ms aggregation after the IN state in which the threshold was not exceed
Multiple-phase system treatment None
Saved waveforms Event waveforms
