- Display, body and power
- Display: 6000‑count LCD with backlight/light screen for low‑light visibility.
Display, Body and Power
- Display: 6000‑count LCD with backlight/light screen for low‑light visibility.
- Sampling rate: around 3 readings per second.
- Dimensions and weight: about 130 × 65 × 32 mm, around 110–120 g without batteries.
- Housing: ABS plastic enclosure with rotary range switch and standard 10 A / mA / COM / V‑Ω input jacks.
- Power: 2 × 1.5 V AAA batteries, with low‑battery indicator.
- Auto power‑off: meter powers down after a period of inactivity to save batteries.
Operating modes and extra functions
- Smart/auto mode: automatically identifies and measures common parameters like AC/DC voltage, resistance, and continuity without changing the dial in basic mode.
- Manual ranges: user can select specific ranges or measurement types as on a conventional DMM.
- True RMS: ensures accurate readings on non‑sinusoidal AC waveforms in AC voltage and current ranges.
- Data hold: freezes the displayed reading.
- Backlight control: separate button for screen lighting.
- Auto power‑off and low‑battery alert as noted above.
Safety, category rating and protection
- Safety category: CAT III 600 V, suitable for measurements on distribution‑level circuits up to that category, with appropriate safety practices.
- Input protection: AC 550 V anti‑burn protection, double fuse protection on current ranges (separate fuses for mA and A), and internal design intended to reduce damage from overload within specified limits.
- Overload indications: display warns or ranges block when outside rated range.
- Compliance: typical listings describe it as meeting general multimeter safety norms; specific standard numbers may not be clearly advertised in all product pages.
