Scope Waveform and Phasor 7
Tips and Hints
Tips and Hints
Scope Waveform gives a clear view of current and voltage waveform shapes. Voltage waveforms in particular should be smooth and sinusoidal. If you see voltage distortion, it is a good idea to check the harmonics display. The rms voltages and frequency should be close to their nominal values.
Waveform and Phasor display are also useful to check if voltage leads and current clamps are connected correctly. In the vector diagram the phase voltages and currents L1 (A), L2 (B), and L3 (C) should appear in sequence when observing them in clockwise direction.
