The 681 is a compact rechargeable digital multimeter built for quick troubleshooting in electrical work, maintenance and electronics. It features a 6000-count LCD with an analog bar display for smoother trend viewing, and it uses auto-ranging with automatic signal recognition, meaning the meter can identify common inputs like voltage, resistance and continuity without constant mode switching. The bright backlit screen and integrated flashlight help when working in dark panels and tight spaces.
This multimeter measures AC/DC voltage, AC/DC current up to 10A, resistance up to 60MΩ, capacitance up to 100mF, frequency up to 999.9kHz, and temperature using the included temperature lead. It also supports NCV non-contact voltage induction, diode testing, continuity beep, data hold, low power prompts and auto shut-down. The body uses ABS with silicone elements for grip and protection, and the set includes a charging cable so you can power the built-in battery without replacing cells.
Technical correction: the description calls it “true effective value” which usually means True RMS. Because the feature list doesn’t explicitly repeat “True RMS”, the safest listing wording is True RMS as described (true effective value) rather than claiming advanced True RMS performance beyond the supplied spec.
