Large-screen LCD screen full display function display voltage, current, active power, power. Display voltage, current, power, energy parameters from the large-screen LCD screen simultaneously. By short press the button to turn on or off the backlight, the backlight status automatic storage. Press the power button 5 seconds until the digital display window flashes, then release the button;. If you press the button again, the consumption data is cleared and cleared quit flashing;.

If you press the button again 5 seconds long until no flashing, the charge data is not cleared and exit cleared. After setting, press the button more than five seconds to automatically save and exit, the scope of active power threshold set for the 0. The wiring order can not be wrong. Shenzhen Focalvalue Technology Co. I wired it inside a 2X4 grounded electrical box as I have posted an image below.

These work quite well and I have them mounted in a plastic panel as a portable meter set for three phase measurements. I put switches in the volage circuit to measure voltage between phases to ground or phase to phase.

Glad to report that this little power meter is working as advertised. Too bad they do not make it the same size to fit in an outlet electrical box, that will be super! Works great for what I needed, which was to measure the energy consumption of a hardwired V pool pump.

Simple installation which is shown clearly on a sticker directly on the back of the device. The core and wires can be easily replaced if they are damaged. Very short wires to the core 10 inches and the device power 20 inches: I knew this so I mounted inside of a watertight electrical box.

The stranded wires to the core seemed quite fragile: I twisted the ends of the stranded wire then used a soldering iron and some solder to "tin" the ends so they would be much less likely to fray and break over time. I still give this product 5 stars for the price, but there are 2 things the manufacturer could do to make this a truly outstanding product: Design the housing of the device to fit into a standard "Decora" switch plate. One end terminates inside the converter where the voltage and CT sense points are located and the other is connected to the Bayite panel mounted in a 2-gang duplex box.

Looks great, works great! I purchased two of these to monitor the power usage within my home while running on my watt generator during a power outage.

These things work great! You can easily monitor the power usage and get more efficiency out of your generator without worrying about miscalculating load.

I installed 2 of these in a v 70 amp distribution panel. I connected the top monitor to the line 1 v and the bottom monitor to line 2 v. Now I can see the actual power load of the appliances in my home which allows me to use things like my toaster oven and microwave that I never thought was possible while on generator.

I buy expensive things because in most cases 1 I know they will work and 2 I know I will get great directions. In most cases where I have sent something back to Amazon it has been because of lousy directions.

I wish Amazon would fact check and require sellers to show more diligence. We all lose money - Amazon, consumers, manufacturers, and sellers - when the consumer has no clue about the precise nature of a product they thought I bought a laser sighting device that i sent back because there were no directions. It showed up in a plastic bag with parts that made no sense.

I sent it back. It had great directions and worked fantastically just as Amazon customers had predicted. The second purchase led to perfect understanding what each of the strange screws and plastic "thingys" did. In many cases i have found products to be outstanding, only to read that the same product got 1 star. Their lousy reviews reflected that they did not understand how the product worked.

By Teck on September 21, Now I can finally see how much power my desktop is finally pulling. I have been trying to get an idea of my power usage and amp draw while in game.

One note I have to make mention of there is really no mounting hard ware for this meter. That being said you need to figure out your own enclosure and mounting style.
