GW INSTEK GPM8310 Digital Power Meter - hands-on review

Hi EVVbloggers,

The GW INSTEK GPM-8310 is an interesting addition to the market for single-phase power meters. Since there are no reviews on that device yet, I reviewed it in detail. Hope you find it useful!

I wish more reviews were this thorough.

GW INSTEK posted a reply to the video review, and expect that many of the comments will be addressed in a new firmware update soon (see link above).

So, looking forward to these improvements and will test the device again after a new firmware version is released!

Great and detailed review, thanks for the effort.

Measurement box adapter is a very useful and recommended IMO accessory with power meter to test mains devices. Otherwise measurement setup gets messy and potentially dangerous with wires going everywhere.
Although expensive, GW-Instek measurement adapter's GPM-001 price is similar to other manufacturers (e.g. R&S HZC815 adapter for HMC8015 power analyser). I not sure I like that universal socket on GPM-001. However, it easy to make DIY version of similar specs.

A couple of days ago (March 18, 2022), GW-INSTEK issued firmware upgrade 1.05 which fixed a couple of issues I addressed in my video.

Among other things, navigation through the screens is made more consistent. Now, the ESC button always brings you back to the previous level. Quite helpful. Small display errors have been corrected (like for the zoom function). Also, the harmonics screen now shows the harmonics method (IEC/CSA/OFF) and allows you to change that setting. I find it still strange that the bars turn completely off when no harmonics method is selected (this should only affect things like THDV and THDI measurements, not the bars themselves). But at least we get to see the setting. There are a couple more changes too.

There are still a number of other issues open, but it’s a (small) start!
