Electronic – Measure high voltages with a multimeter

high voltagemultimetervoltage measurement

My multimeter is rated to 600V. How can I readily (and safely) use it to measure higher voltages?

Best Answer

The safest way is to buy a high voltage probe that is compatible with your meter.

I use a Fluke one that is rated at 40kVDC. Note carefully that this kind of probe is adequate for DC or mains-frequency. If you have higher frequency high voltage it is not necessarily safe.

Also, if you are using it on mains voltage make sure it is rated for the proper category for the situation or you may be at great personal danger from arc flash. Do not use an inadequately rated or unrated multimeter or probe in situations where high fault currents can occur.
