5.4.1 Output voltage measurement
When “MEASURE” has been selected in the MISC menu, RMS value (RMS), average DC (AVG), or
peak value (PEAK) is displayed.
The initial setting (factory setting) is to display the RMS value (RMS).
See “3.4.9 Using measurement functions”.
a) RMS value RMS value of AC+DC
•
Full scale: 250.0 Vrms: 100 V range
500.0 Vrms: 200 V range
•
Display resolution: 0.1 Vrms
•
Measurement accuracy: at 45 Hz to 65 Hz
±
(0.5% of rdg + 0.3 Vrms): 100 V range
