Measurement Of Extreme And Mean Voltage And Current Values - AEMC PowerPad III 8336 User Manual

5.3.4 MEASUREMENT OF EXTREME AND MEAN VOLTAGE AND CURRENT VALUES

The sub-menu displays the RMS, maximum, minimum and average values for voltage and current, as well as the
instantaneous positive and negative voltage and current peaks.
NOTE: The display screen varies depending on which value is selected.
● 3U: Displays the one-second mean and half-cycle maximum and minimum RMS values and the instantaneous
positive and negative phase-to-phase voltage peaks.
● 4V: Displays the one-second mean and half-cycle maximum and minimum RMS values and the instantaneous
positive and negative peaks of the phase-to-neutral voltages and of the neutral.
● 4A: Displays the one-second mean and half-cycle maximum and minimum RMS values and the positive and
negative instantaneous peak values of the phase and neutral currents.
● L1/L2/L3: Displays the one-second mean and half-cycle maximum and minimum RMS values and the
instantaneous positive and negative peaks of the phase-to-neutral voltage and of the current of phase 1.
● N: Displays the RMS values and the positive and negative instantaneous peaks of the neutral relative to ground.
The columns display the values relative to each voltage, current or neutral graph.
Item Function
MAX
Maximum RMS phase-to-phase voltage since the instrument was turned ON or the last time
RMS
True RMS phase-to-phase voltage
MIN
Minimum RMS phase-to-phase voltage since the instrument was turned ON or the last time
PK+
Maximum (positive) peak phase-to-phase voltage since instrument was turned ON or the last time
PK-
Minimum (negative) peak phase-to-phase voltage since instrument was turned ON or the last time
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.
To reset the MIN and MAX on the display, press the
