Hello Experts,
With Fluke make 28II model digital multimeter, can user measure out put voltage of 611 drive at out put terminals? Fluke 28 II AC voltage bandwidth id 15 Hz to 20 KHz.

Thanks in advance.

DEEP.

Usually it is not possible to make a propper measurement of inverter output voltage with a multimeter.

To do so, you need a scope or a very special instruments.

Yes I do agree, but it is applicable to ordinary make multimeters, which are designed to measure AC voltage at 50 or 60 Hz. I am asking about Fluke make model 28 II, wherein its specification state as AC voltage bandwidth is 15Hz to 20 KHz. So I wanted to know, if anybody has used such type of multimeters to use inverter output voltage or can we use this type of instrument for measurment?

I am afraid that 20kHz means SINUS WAVE...

Inverter output is NOT Sinus wave!

Voltage is a couple of spikes with high frequency!

Pleas try a scope, you will see what I mean.
