⚡️ DROK DC 4.5-100V LED Voltage Current Display - Digital Voltmeter Ammeter Multimeter Panel for Automotive Motor Battery - 0-50A Volt Tester Meter Amp Detector - Voltage Amperage Monitor Gauge Review

This easy to use meter is an excellent monitoring tool for DC solar systems. - Notice to designers; The meter shunt is installed on the negative terminal, so design it accordingly and do not use negative ground installations on the battery side where a negative ground could short out the shunt. Directly from solar panels or an isolated bridge rectifier of a wind turbine, this very clear quality meter is ideal for currents up to 50 amperes and 100 VDC.

I ordered two of these devices for my solar energy project. I have two 80 volt power supplies with a maximum current of about 10 amps. I built a special box and panel for two meters. The box is fairly tight and the wires feeding it are 8 gauge. I mounted it high up on the wall, two channels side by side. The first day worked great. The second day is not very good. The left display works half a year later. The right one didn't work except for the first day. I ordered old analog gauges to…

Make sure the meter wiring and jumpers are done exactly as shown in the diagram on the back of the meter. plus to your charge and the V+ screw on the meter. Negative from the load to the large screw on one side of the shunt. The small screw on the same side as the Ain screw on the gauge. On the opposite side of the shunt is a large screw to the negative of the power supply and a small screw to the COM screw on the meter. After properly connecting the wires, I adjusted the calibration…

Current readings are inaccurate, voltage readings are quite close. While it does have current (and voltage) adjustment, it's not enough to correct the amp's displayed readings. The current display only shows half of what it should (i.e. 14 amps only shows as 7 amps). Below about 1 amp it reads "00.0" it should read tenths of amps. I've tried two of these gauges and both have this problem. This has also been discussed in other reviews. Gave two stars instead of one because the voltage readings…

Does exactly what I wanted (measure battery current in my camper) but I had to 'interpret' the circuit a bit to get what I wanted. Now it's built into the camper and will display battery voltage and current 0.00 when the battery is discharged and when external AC power is applied it will display the charge voltage and current as I had hoped. Excellent! I don't know if the current reading for ma is accurate, but it suits my needs and shows 0.00 when the battery is fully charged. this is not what

This gauge is easy to read and the instructions printed on the back of the gauge are adequate. The initial voltage reading was accurate, but the current reading was about half what it should be. There were no printed instructions but I removed the lid and found the calibration pots. The voltage calibration was fine, but the current setting never reached the correct value, leaving an error of about 2% or 3%. It was worth one star. from the overall rating and 2 stars from the accuracy rating. Now

Please see my edit below :) I just received this today. First test I do: - I'm using a 9V power supply (green [-] and yellow [+] wires in the lower right corner of the picture) - all the wires are done (color coded for a better view). ) - all cables were checked for continuity - the motor turns - the multimeter shows that there is 9V, the article says to contact them, but I still don't understand how I feel. Perhaps the motor consumes almost no current, what shows nothing?there are no…
