Review on 🔌 DROK Digital Multimeter DC Power Monitor, 6.5-100V 20A Voltage Amperage Power Energy Meter with Built-in Shunt, LCD Digital Display Volt Amp Tester Gauge by David Ramirez

I have a 3 digit voltmeter that I use to monitor the 12 volt battery in my car. This is useful, but it could be 12.69 or 12.61, still accurate to three digits. In addition, this is not entirely correct. So I was looking for four digit accuracy in a voltmeter. The DROK counter is the solution I chose. This is a nice backlit display with an internal 20 amp shunt. Currently I'm only using the voltmeter function, so I can't comment on other functions. The voltmeter is accurate to within 0.05 volts at the 12 volt end of the scale. I haven't used it at higher voltages. It seems to be constantly low, 05 volts, so if I see a voltage of 12.66, for example, I know it's actually 12.71. I've tested this multiple times with my Fluke.
