AC/DC clamp meter for electrical testing

The TENMARS TM-1015 measures AC and DC current up to 400 A with a 3¾-digit LCD showing 4000 counts. It also covers AC and DC voltage to 600 V, resistance to 40 MΩ and continuity with a buzzer below 40 Ω. Auto-ranging, data hold, max/min capture and a backlit display support daily fault-finding work.

Electricians and technicians needing non-contact

Suited for professionals who must measure live conductors up to 30 mm diameter without breaking the circuit. The clamp jaw and double-injection case are built for regular site use. Buyers who require true-RMS response, inrush current capture or temperature measurement should consider other instruments.

400 A AC/DC current range with ±(2.0%+10) accuracy

This single specification defines the measurement ceiling and tolerance for both alternating and direct current. If the application demands higher current or tighter accuracy, this model will not meet the requirement.

Questions about this item

Which measurement range should I select for typical household wiring?

The TM-1015 covers 10 mA to 400 A on both AC and DC current, so a single range handles everything from low-current circuits up to main feeders.

What does the 4000-count display mean for reading resolution?

The 3¾-digit LCD shows up to 4000 counts, giving 0.1 mV resolution on voltage and 0.1 Ω on resistance for fine detail.

How does the clamp opening limit what I can measure?

The jaws accept conductors up to 30 mm in diameter, suitable for most single cables and small busbars in electrical panels.
