I am installing 3 meters to monitor solar panel output. I can use a clamp meter to check the amperage and during the tests it will read 1 to 6 amps. The meters read 0 to 2 amps. I have tried to calibrate them and I can get them to read correctly but as soon as I take the screwdriver away they return to the lower reading. How can I get them to read accurately. I have tried reversing the shunt wires and get the same result. Is there a better meter that will work, I am ready to return these.

I’ve just received my volt meter (DROK® Mini Digital Voltage Tester DC 3.0-30V Voltmeter Detector 0.40″ Blue LED Panel Display) and decided to test it out with a 9v battery and it did not work. Am I suppose to do anything special in order for the display to work.
Hello Robert Porter, did the LED lights up? then what’s your wiring? Could you please send send us some photos to let us check what is the problem detail?
