Simultaneous Display - AEMC 8335 User Manual

Note: The Max and Min RMS measurements are calculated every half-period
(e.g. every 10ms for a signal at 50Hz). The measurements are refreshed every
250ms.

5.1.5 Simultaneous Display

This sub-menu displays all the voltage and current measurements (RMS, DC,
THD, DF, CF, PST, KF).
NOTE: The display screen varies depending on which value is selected.
Item Function
RMS
True effective value of voltage or current
DC
Direct component
THD
Total harmonic distortion rate
DF
Distortion factor
CF
Peak factor calculated in relation to the displayed waveform
PST
Short-term flicker (over 10 minutes)
KF
K factor - Oversizing of transformer relative to harmonics
Note: L2 and L3 give information concerning simultaneous display of the current
and of the voltage respectively for phases 2 and 3.
