7.1.2 AC Voltage Measurement (ACV, ACV(AC+DC))
Measurement method True RMS measurement, RMS display
Input range 5% or more of a full scale
Crest factor 3:1 at a full scale (This is restricted to the maximum allowable applied
voltage.)
Temperature coefficient (1/10 of measurement accuracy that includes the additional error)/C
in
each range and frequency range
Response time Approx. 1 s (Time until the measurement value reaches within 0.1% of
the final value in the same range)
