nice little meter with a bright color display
I like this meter. The colors show up well even in bright outside light. I'm using several of these to measure the output of my solar inverters. As the instructions state, it doesn't matter which direction the current is flowing. It will measure in both directions, just not differentiate between the two. They also fit well among other DIN breakers.

Heat Pump
I have bought 5 of these, I used 2 for the 240v heat pump one for the month of power used, one for the total season power use. I like the reset button, when the electric bill arrives I reset the month one and multiple the Kw by the cost per Kw, mine 0.24It can be used either on 240v or 120v

Why 240V between Hot#2 and neutral???
The media could not be loaded. Good monitor. Seller sent replacement products with one call. Comes with a basic wiring diagram.As pictures and video show, I am using two monitors to monitor each leg of a single phase 30amp 120/240 volt generator circuit feeding my house during power outages. because the Generator only has an hour meter (Predator 9500 Inverter Generator).The issue I have is Monitor #1 shows correct voltage (124.8 volts between X/L1/Hot leg #1 and neutral) BUT Monitor #2 voltage measurement is incorrect (250+ volts between Y/L2/Hot leg #2 and neutral). The reason I know that is when I test points 1 & 2 on Monitor #2, my Fluke 87V meter indicates 124.9 volts not 250+ volts. I tried two additional meters the seller sent me only to get the same incorrect voltage.I also tested the generator to make sure it was generating the correct voltages with my Fluke 87V as well, which it was (124+ volts between X and neutral & 124+ volts between Y and neutral).I have included my wiring diagram with the exact components used in my electrical system.Any help from Electrical engineers or experienced electricians would be greatly appreciated as to why Meter #2 is showing 250+ volts?The materials/components I used in this system are as follows:- Midwest R281CB1LK meter socket/distribution panel- Midwest model #GE200ZUL 150 & 200 amp interlock kit- Predator 9500 Inverter Generator- smseace circuit breaker distribution box (8 way)- Wago 10awg Lever nuts (5 conductor and 3 conductor)- GearIT 40 feet 120/240 volt 30amp locking power cord for generators- #10 awg thhn single conductor stranded wire- two Keotek single phase energy monitors (D52-2047HD)- GE model # T030N 30Amp temporary power inlet1-1/2” rigid conduit LR, Myers hubs & close nipples3/4” rigid conduit Myers hubs and close nipples12”x12”x1/8” Aluminum plate cut to fit the smeace 8 way box1/4” & 10-24 Caulk-in anchors, 1/4” hardware, & 10-24 hardwareThanks for any knowledge or help you can share with me.

Excellent power meter
Before I bought this device I looked at reviews from users who used it before me and when I bought it I found that it is really an excellent device
