Measure Power Consumption With Multimeter

Your multimeter might not be fast enough to register this and might not notice this if the power supply can handle this.

Measure power consumption with multimeter.

I was thinking that it should be possible to achieve this by connecting the measuring hands of the meter to the connectors in the power socket and then over a couple of minutes measure first the average voltage and then the average. I had a dc motor that needed 3a current to start after it was running the current use dropped back to under 1a. Your multimeter might have completely separate ports for measuring amps while the other port is specifically just for voltage resistance and continuity but most cheaper multimeters will share ports. What i d like to know is if it is possible to do this sort of measurement with a multimeter perhaps just by wiring the multimeter to the head of the power chord then plugging it in and measuring the current of amps.

In this beginner s guide we ve shown you how to use a multimeter. Then amps voltage watts. Furthermore measuring anything over 10 amps could blow a fuse or destroy the multimeter as well. I want to use an inexpensive multimeter to measure the average power consumption in an appliance computer.

If you re looking for a multimeter you may found this post useful best multimeters under 50. You ve learned how to measure voltage current and resistance and how to check continuity. Ya the kill a watt meters are not the greatest. This happened to me when i started using my desktop power supply.

The kill a watt meter measures kilowatts and kilowatt hours. A multimeter is an essential tool in any electronics lab.
