Review on ⚡️ Mini Digital DC Voltmeter: Waterproof, Dustproof, Drop Resistant Tester - 3 Colours (Red, Green, Yellow) by Michael Moulton
Affordable and small, draws about 10mA, set and forget.
Everything worked fine, most were blocked with my DMM, two were clipped at 0.03V. The DMM, which is a current clamp meter in the mA range and is much more accurate than whatever I have, gave me 00A. I double checked the spec and its resolution is 1mA so that should have worked. If I find time I'll check with a third DMM so I can give you a good average power consumption. The power consumption is so important to me and maybe few of you because I connect it to a battery with a small solar panel that has to run for a long time and only 10mA is a lot in my situation.
- detection voltage: 3.0V DC current 30V; Working current: 200ms/time; Measurement accuracy: 3%; Maximum working voltage: 30V; Operating Temperature: -10 +65℃
