Easy to hook up. Good instructions.

I bought this to monitor the output of a AC-DC power supply. The Voltage Reading is accurate as my Fluke Meter. The Amperage is close to my Fluke Meter Clamp reading. I'm guessing the Watt and Whr reading are close enough. The backlight is bright blue and easy to read indoors. The One-button setting is a bit difficult to figure out but it does function as intended, The high-low voltages can be set. It beeps when it powers on and displays the shunt setting. It stops working below 5V and there is no alternate power input if below 5V, not a problem for me as I intend to use it 100-150VDC. The shunt has a plastic shroud which is an advantage over other sellers.What I don't like about it is that it displays both Chinese characters and English Characters on the display. I could not find a setting to remove the redundant Chinese characters. That's a bit insulting to the USA market for this device.

I purchased the 50A model. This is one of the few brands that go up to 200VDC. It monitors the output of a 2KW solar array. I checked its accuracy with another meter and both the current and voltage were good. The measurements auto range so low values have increased resolution which decreases when displaying large values. It is easy to see the display from all angles and the back light is a nice touch. The shunt can dissipate over 3W when fully loaded so keep it open to the air. It retains the accumulated energy when power is removed but it can be manually reset.
