VOLTCRAFT VC-522 (ISO) Digital Clamp Meter, True RMS, CAT III 600V, 4000 Counts, ISO Calibrated, Measures AC/DC Voltage, AC Current, Resistance, Capacitance, Frequency, Temperature VC-9499265

The VOLTCRAFT VC-522 (ISO) stands apart from typical clamp meters by combining ISO calibration with true RMS accuracy and a broad measurement range in a compact, rugged design. It is the go-to tool for electricians and technicians who require reliable readings on distorted waveforms and need documented calibration for quality assurance.

Highlights

• ISO calibrated for traceable measurement accuracy
• True RMS sensing for precise AC measurements on non-sinusoidal signals
• CAT III 600 V safety rating for industrial environments
• 4000-count digital LCD with backlight for clear readings in any light
• Jaw opening of 30 mm accommodates conductors up to 400 A AC
• Measures AC/DC voltage, AC current, resistance, capacitance, frequency, temperature, diode, and continuity
• Auto-ranging with data hold and low battery indicator
• Powered by 2x AAA batteries (included)

In daily use

On the job, the VC-522 (ISO) simplifies troubleshooting. Clamp around a single conductor to measure AC current up to 400 A without breaking the circuit. Use the test leads for voltage, resistance, capacitance, frequency, and temperature. The backlit display and data hold function allow you to work in tight or dimly lit panels. The acoustic continuity tester speeds up wire tracing, while the diode test checks semiconductor junctions. With auto-ranging, you can focus on the measurement, not the dial.
