Voltcraft VC-351 Digital Clamp Meter CAT III 600 V AC/DC 60 A True RMS 6000 Counts

Electricians and HVAC technicians working on live panels need a clamp meter that delivers precise True RMS readings without breaking the circuit. The Voltcraft VC-351 digital clamp meter meets that demand with CAT III 600 V safety, AC/DC current up to 60 A, and a 6000-count backlit display. Its 17 mm jaw opens wide enough for common conductors, while auto-ranging and data hold simplify fast measurements in tight spaces.

Key specifications

• AC/DC current: 0.01 A – 60 A
• AC/DC voltage: 0.1 V – 600 V
• Resistance: 0.1 Ω – 60 MΩ
• Capacitance: 1 nF – 60 mF
• Frequency: 10 Hz – 10 kHz
• True RMS for accurate non-sinusoidal waveforms
• CAT III 600 V safety rating
• 6000-count digital LCD with backlight

Why choose it

True RMS technology ensures reliable readings even on distorted waveforms from variable frequency drives or switching power supplies. The CAT III 600 V rating allows safe use on distribution panels and fixed installations. The compact design and backlit display make it practical for fieldwork in dim environments, while the included functions cover most daily electrical diagnostics.

Ideal use cases

• Measuring current on branch circuits without disconnecting wires
• Verifying voltage and continuity in residential and commercial panels
• Troubleshooting motor controls and HVAC systems
• Testing capacitors and diodes on electronic boards
• Field service where a lightweight, battery-powered meter is essential

Good to know

The VC-351 uses two AAA batteries, which are easy to source. The 17 mm jaw accommodates conductors up to roughly 500 MCM, covering most standard building wires. Auto-ranging reduces setup time, and the data hold function lets you record readings in awkward positions. The meter is built to withstand daily job-site use with a robust housing and clear, responsive controls.
