hello everyone
Am using a kelly induction motor controller KIM7210. It generates a three phase AC from a 72Volts DC power supply.
I tried to measure the parameters like voltage ,current and frequency using my protek multimeter. But when i do the calculations
based on the input and output values there is a huge efficiency contradiction. So am planning to buy a new digital multimeter which would display the accurate value of the voltages ,current and frequency of the three phase waveform. The voltage i want to measure is a 40Volts 3 phase AC and Maximum current of about 50Amperes.
So please suggest me a good meter which will have the low pas filter capability which would be immune to supply noise and would
display the accurate values of the above said parameters. And also tell me whats your view on using fluke87V and Fluke 289 for vfd measurements.
