Review on AstroAI TRMS Digital Multimeter: 4000 Counts Auto-Ranging Ohmmeter Voltmeter, Battery Voltage Tester for 1.5v/9v/12v, Measure Voltage Current Resistance Diodes Continuity Capacitance with NCV Function by Bill Sorenson

Revainrating 5 out of 5

Works as described, accurate and powerful.

I really can't fault this multimeter. It does everything I need at an affordable price. Aside from basic AC/DC voltage and current and resistance, the diode and continuity test works as described with a buzzer and LED indicator. Note that there is a delay in checking for continuity; Don't assume the two circuits aren't shorted after a very fast probe. Another minor complaint I personally have is the limited exposed surface area of the probes themselves; This can be a plus or a minus depending on the use case. Compared to several popular meters and oscilloscopes, DC measurements are relatively accurate and suitable for every application I have (except for preamp measurements). The backlight, backlight, and LED display are nice touches that, while I haven't benefited much from them, are sure to come in handy in certain scenarios, especially in the dark.
