14000-count True RMS

True RMS from 40 Hz to 1 kHz reads AC voltage to ±(1.2% + 5) and DC to ±(1.0% + 5). Resistance spans 400 Ω to 40 MΩ.

2NCV with sound, screen and LED alerts

It senses AC voltage without contact to find live wires, warning by beep, display and LED at once. The safety rating is CAT II 600 V.

3Backlight, torch and auto-off

Data hold, a backlit LCD and a built-in torch make dark, tight spots easy to read. There’s a low-battery indicator and 15-minute auto power-off too.
