MUSTOOL MT336 600V True RMS Digital Clamp - 400A Measurement

Have you ever measured AC electrical current up to 400 amps and still managed to see the graph on the oscilloscope it has built-in? It is possible to measure very high currents using this equipment!
Its advantage is that it is a multimeter too, and that pleased me a lot. Electricians will benefit greatly as it is possible to see if the current waveform is being distorted. When you operate machines that have an AC motor they have inductors in their windings. This causes a deformation of the sine waveform causing a loss of efficiency and consequently a lower power factor.
But it is very difficult without this instrument for you to see the current waveform as oscilloscopes normally show the voltage waveform.
In this video I show the current of a fan with an AC motor controlled by a circuit that uses a TRIAC very similar to the one used in AC lamp dimmers.
Even if you are measuring a three-phase motor you can notice the efficiency and distortion between different inverter boards, which as we know have different levels of sophistication.
