Review: Technical Review - TL;DR - Accuracy is much greater than the spec. The display is bright. The documentation is in Chinese but has been translated below. good bang for the buck.

Accuracy I found it to be only 4.8mv off at 7.7000V which is 0.06234% error rate this exceeds its spec of +/- 0.3% the test was done with a 120000 count meter that is in calibration. current requirements.

Review: Slow update and not accurate and failed already. - Two major problems with this T-HOT voltmeter, it is slow to update and not accurate enough with no way to recalibrate it. And it has already failed. Was using it to monitor a 12v power supply with the meter powered from a separate source and now the meter is reading 34 volts even though the power supply output is actually 12.4 volts. Tried powering it on/off/on a few times but did not fix it. With the meter input grounded, it is reading a negative voltage. Confirmed the actual input V with one of my Fluke meters. Definitely has failed.

### ⭐⭐⭐⭐⭐ EXCELLENT, Hi-Res, panel Voltmeter
*by M***M on May 18, 2025*

I am very impressed. The readings are spot on when measuring 12V and 24V, at millivolt resolution, compared to my CALIBRATED DMM's. Run them off a 9V battery to isolate from DUT (device under test). Only downside is that two of these meters will kill a 9V battery in one day, if you leave them ON.
