Digital Multimeter, 4000-Count TRMS, 1000V AC/DC

TRMS digital multimeter delivers accurate AC/DC voltage readings up to 1000V, plus resistance and continuity checks for faster troubleshooting. The 4000-count backlit LCD and switchable auto/manual ranging make it easy to capture stable measurements in panels, outlets, appliances, and field wiring. Built-in insulation resistance testing supports common test voltages, while safety ratings and a rugged housing help you work with confidence.

• Measures AC/DC voltage (up to 1000V), resistance, and continuity for everyday electrical diagnostics.


• Tests insulation resistance at 100/250/500/1000 VDC with ranges up to 10 GΩ for cable and motor checks.


• Delivers TRMS accuracy on non-sinusoidal waveforms for more reliable real-world readings.


• Improves visibility with a 4000-count backlit LCD, bar graph, and data hold for quick-scan results.


• Protects work with CAT IV 600V / CAT III 1000V ratings, IP40 housing, and 15-minute auto power off.

Designed for technicians and serious DIYers, this compact voltage tester and ohmmeter helps you confirm power, verify continuity, and evaluate insulation condition without juggling multiple tools. The RANGE key lets you switch between auto ranging and manual control when you need consistent readings. Clear status indicators (low battery, over-range, polarity) reduce guesswork during time-sensitive jobs. Keep it in the included bag with the supplied leads and clips, and grab yours today for cleaner, faster electrical checks.
