Versatile Electrical Tester

This AstroAI digital clamp meter measures AC and DC current, voltage, resistance, capacitance, frequency and duty cycle. It also performs diode, continuity and live-wire tests with audible and visual alarms. The 4000-count auto-ranging display suits electricians, technicians and serious DIY users diagnosing industrial or household circuits.

Compact Clamp Integration

The slim jaws open wide enough to clamp around conductors without breaking the circuit, while the 195 x 68 x 29 mm body fits into tight panels. A backlit 35 x 25 mm LCD and built-in flashlight illuminate dark enclosures. Auto power-off after 15 minutes preserves the two included 1.5 V AAA batteries, and a storage bag keeps leads organised.

Steady-State Measurement Behaviour

Sampling runs at three times per second, giving stable readings during extended monitoring of motor starts or load variations. The ZERO function cancels offset from the Earth’s magnetic field, improving accuracy on low-current DC signals. CAT III 600 V rating and pollution degree 2 compliance support continuous use on fixed installations up to 2000 m altitude.

Questions about this item

How long does the clamp meter run before the auto power-off activates?

The meter turns itself off after 15 minutes of inactivity to preserve the two 1.5 V AAA batteries.

What audible and visual signals does the non-contact voltage detector give?

A green light and slow beep indicate a weak AC signal; a red light and rapid beep indicate a strong AC signal.

Which test leads and power source are included so the meter works immediately?

The package supplies a pair of test leads and two 1.5 V AAA batteries.
