Waveform Mode; Rms Measurements - AEMC PowerPad III 8336 User Manual

5.3 WAVEFORM MODE

The Waveform mode displays the current and voltage graphs, along with the values measured and those calculated from
the voltages and currents (except for power, energy, and harmonics). This is the screen that appears when the instrument
is powered up.
Item Function
RMS
Measurement of the true RMS value
THD
Measurement of total harmonic distortion
CF
Measurement of the peak factor
Display of Min/Max, RMS and peak values (see § 5.3.4)
Simultaneous display of the following measurements: RMS, DC, THD, CF, PST, PLT, FHL and FK (see § 5.3.5)
Display of phasor (Fresnel) diagram of signals (see § 5.3.6)

5.3.1 RMS MEASUREMENTS

This sub-menu displays the waveforms over a period of the measured signals and the true effective values of the voltage
and the current.
The choice of graphs to be displayed depends on the type of electrical connection that was set up during the configu-
ration (see § 4.1.4).
