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.

Hi Robert Porter,

Did it work when you received it? and did the LED lights up? what’s your wiring? Could you please send send us some photos to let us check what is the problem detail?

Then please tell me your order number? Maybe you can contact us from your order then we can deal with it directly.

Looking forward to hearing from you.
Best regards,
DROK

I ordered from amazon on 11 may 16 and received on 13 may 16 one ” 0.96″ portable OLED multimeter DC 33V 3A” panel meter. when I apply voltage between the small red wire and either the large or small black wire, the unit stablizes a current draw of 5 mA at about 5 volts supply, which seems normal for these units. However, the display does nothing at all.
I tried holding the reset button while powered up, and during power up with no effect. The display remains totally dark.

suggestions ??
