The Voltcraft VC‑522 and VC‑523 are compact, rugged CAT III 600 V clamp meters designed for everyday electrical diagnostics. Both models deliver true RMS accuracy with ±0.8 % precision and feature a 32 mm jaw opening for AC/DC currents up to 400 A. They measure voltage up to 600 V, resistance up to 40 MΩ, capacitance up to 4000 µF, frequency up to 10 kHz, and temperature from –20 °C to 760 °C using a K-type probe. Functions such as diode testing, continuity checks, auto-ranging, data hold, and non-contact voltage detection (NCV) are standard, along with LED illumination for low-light work. The VC‑523 adds refinements for professional use while maintaining the same measurement ranges and ergonomic design.
For higher demands, the VC‑532 and VC‑533 offer expanded capabilities with a 37 mm jaw opening and AC/DC current measurement up to 1000 A. Both models include a 6000-count backlit display with bar graph, resistance up to 60 MΩ, capacitance up to 6000 µF, and temperature up to 1000 °C. They feature REL reference mode, NCV detection, diode and continuity testing, and LED illumination for confined spaces. Encased in durable two-component housings with slip-resistant grips, these meters are ideal for industrial maintenance, switchgear work, and high-current diagnostics where precision and safety are critical.
