Built-in CT wiring diagram
- When power on, the meter display the measure parameters.
- When power on, you can press the button of SAM CK last for 5 seconds,
- then the electric energy will to be zero and start to cumulate when release the button.
- And when power off, the meter can save the value of electric energy and go on cumulating data when the meter power-on next.

Was going to use for some 240 circuit use; but put it to use on a standard 120VAC circuit, followed by some extensive testing with known standards and against the industry standard "Kill-A-Watt". This thing ROCKS!!! It is vastly more accurate than the "Kill-A-Watt" (which is also an energy vampire, BTW). LOVE this item. May look abit cheap; but I am amazed with it's results. Only downside is the itty-bitty "RESET" button for the kWh data (use the tip of a retracted ballpoint to activate it -- with a 3+ second press). I will be buying more of these.

I purchased to replace my existing monitors that I installed 5 years ago. Looks at my photo if you are trying to run 2 monitors for a split phase 240v setup. This is the only way to accurately show split phase numbers. Overall, easy install and numbers/values are bright which was my biggest concern. All good so far.

Installed in my rv to check power usage as our park has pay for power and now I can compare usage. Advantage is now able to see instantly what voltage, current and wattage is at any time. Very pleased with this product.

There is an error in this product description relating to the load current measurement. In fact, it is said that we may use either the internal transformer (CT) or the external one. According to my painful experience of connecting this device, by passing the load-current wire inside the hole of the meter, the load current remains zero, thus indicating that there is no internal CT or it is not functional. On the other hand, using the external small CT around the same load-current wire, I got finally correct current readings.Where is the truth? No internal CT or non-functional internal CT.The description of the product must reflect its technical characteristics. It is crucial for both the buyer and the seller.The mounting box is just perfect.Service from the seller is quite inadequate.

I’m using this meter on my Single Phase 240 volt pool pump, the Energy Meter was wired to also run on 240vac. It reads accurate and agreed with my volt meter and amp probe.I changed the pool pump contactor to one that could handle more current, this contactor only had a 120vac coil. I also had 120vac in the box so I wired the Energy Meter to run on 120vac. Now it’s only indication half of the power even though the pump is running on 240vac and my amp probe is showing a 6 amp draw.I could rewire the Energy Meter back to run on 240vac. I just want to know why it isn’t reading correctly.The other Energy Meter I have is connected to my pool heater, it runs on 120vac and the meter is connected to 120vac, it reads accurately.UPDATE: July 16, 2024And for all of you that said I need 2 meters why does it read correctly when the meter is powered by 240 V single phase and not 120 V? The current that the pump draws is the same whether the meter runs on 120 or 240. I changed the meter to run on 240 and now it reads correctly. Whether it runs on 120 or 240 it’s still single phase, the neutral and ground legs aren’t drawing any current.

I purchase two of these to monitor my solar arrays. Once installed and turned on, Everything works as expected. My only complaint is I wish the display was brighter due to my application, the meters are located in a weatherproof box outdoors visible through a window. The sunlight makes the display hard to read.I will purchase two more when I complete my second array.

Followed the instructions to a T and it did not work. Got help from electrician buddy and the one thing I missed /did not do was not in the instruction steps. Instructions need to be more detailed.

Added this to a home built charging station for my EV because its self reporting of its State Of Charge is quite variable. With this I can see how many KWH were used for each charge, a better metric for my purposes. Two comments for your consideration:1) There is no hard plastic over the display; its designed to be within an enclosure. You can easily damage it.2) The reset button works but on mine is hard to press. I left an old toothbrush next to it so I can depress the tiny hard button with the end of it. I suspect in time this switch will break and I will add a better external button by soldering wires to the pads in there.
