HiLetgo Digital Multimeter AC 80-260V 100A PZEM-061 LCD Display Digital Current Voltage Power Energy Multimeter Ammeter Voltmeter with Current Transformer CT

The media could not be loaded. I like it. Clear display. Simple to connect (just 4 wires). Shows V, A, W, and Wh (i.e., energy delivered).Note that A, W, and Wh are measured only in one direction. In the other direction, they show A=0, W=0, and Wh does not change.Sometimes when initially connected, the backlight and the voltage value flash. I'm not sure why.

The item came fast and well packaged, and it's bigger that I thought it would be (which is good as most of it is a display). The input and output is clearly marked on the back of the unit, as well as in the manual. There is a single button which is used to turn the backlight (it's blue by the way) on and off, as well as to reset the unit (as it keeps the energy counter even if turned off).I have tested in with voltages from 5 to 20 V and with currents from 0 to about 2A. Both the voltmeter and the ampermeter are quite precise, compared to other measurement tools I have and trust: the voltage is within 0.05V, and the current is within 0.001A as far as I can see. Measurements change every second or so, which is less frequent than your average multimeter.The screen is well readable from left, right, and down sides, but less so from the up side that is usually the case with liquid crystal displays, so take that into accounting when you mount it.One other remark is, the description says the lowest voltage is 6.5V, which is true except the backlight only comes in from about 7V, so I would say if you're going to need a backlight, consider the lowest voltage at say 7.5V to be on the safe side. Now, the upper limits are 100V and 20A as per description and documentation, unfortunately I don't have equipment to push the device to its limits.Finally, I have tested the alarm function and it works fine. You can set the two voltage thresholds (upper and lower), and if the voltage is not within the range specifies, both display and backlight flashes rapidly. This might come handy if say you need to prevent your lithium battery from discharging too much (i.e. undervoltage).I am giving it five stars overall, but especially for its precision.

I wanted something to accurately measure the amount of amps I was pulling from my inverter to run the lights in my greenhouse. I found this little meter to be very helpful and quite accurate. It at a great price. I bought my 1st one more than a year ago and it's still works perfectly on my other inverter. I found these meters to be a good item at a great price.

Works well in my homemade power station and tester. Plan on using your experience or intelligence to know how to work its features, as mine had no instructions how to set the backlight or anything. Just 1 button on the face to hold or push for settings, and I really don't know what the settings all are or how to navigate them by just 1 button and no instructions. Easy to wire up, the diagram is on back of the case, and a small screwdriver is only needed

Shows volts, amps, and watts, and accumulated watts (easily resettable), with a backlight if you turn it on. Easy to wire up. It measures about a volt more or less than other low-cost meters that I have, but I don't know which one (if any) is correct. The accuracy is good enough for my hobby project.

Excellent meter.It is also accurate (compared with an expensive meter)It almost fits in a plastic socket box with a standard faceplate.A little bit of filing lets the meter fit in a stainless steel faceplate

Hooked 2 of these up on roof heat tape circuits after one heat tape cable died last year and there was no way to tell. It could have resulted in ice dams which let water into the house. So now I can just look at these every day in the winter and insure they're drawing about the amount of electricity you see in the lower left of each unit. Pretty accurate too, as the left circuit has a single 500w heat tape cable on it. Close enough and this is the cable that failed last year. The right circuit has more cables attached to it but if it falls by more than 100w (20 foot cable), then I know something is wrong.
