True RMS Clamp Meter for Automotive & Home Use

This aFe Power clamp multimeter measures up to 1000V AC/DC voltage and 20A AC/DC current with 6000-count True RMS accuracy. It handles resistance, capacitance, frequency, duty cycle, diode, continuity, transistor hFE and temperature in one handheld tool. Auto-ranging removes the need to select manual ranges for faster diagnostics.

Compact Clamp Design with NCV Safety Alert

The clamp jaw lets you measure current without breaking a circuit, while the non-contact voltage detector gives audible and visual warnings on live conductors. At 189 mm long and 1.32 lb it fits a tool bag easily and runs on standard batteries. CAT II and CAT III ratings cover household and light industrial panels.

Replaces Separate Voltage.

Technicians who now carry a voltmeter, ammeter and thermometer can consolidate to this single device. The jump is worth it when you need True RMS on noisy waveforms and want clamp convenience plus NCV safety in one calibrated instrument. Buyers who require higher current ranges or bench-grade resolution should look elsewhere.

Questions about this item

What does the 1000 V CAT II / CAT III rating limit in practice?

The meter is rated for 1000 V AC/DC under CAT II and CAT III, so it can safely measure mains and fixed-installation circuits up to that voltage.

Will the 189 mm jaw opening fit around a standard 20 A automotive fuse block?

The clamp jaw spans 189 mm, wide enough for most single conductors and small cable bundles found in automotive fuse blocks.

How do I switch to the 20 A current range without blowing the internal fuse?

Select the A function, clamp the single conductor inside the jaw, and keep the test leads unplugged; the auto-ranging chip selects the 20 A scale automatically.
