The CZD VC60B+ is a professional-grade digital insulation resistance tester designed for electrical maintenance, industrial equipment testing, and cable integrity verification. With a robust red protective casing and a clear LCD display, this device offers high-precision measurements up to 1000V, making it an essential tool for electricians and engineers working with motors, transformers, and power distribution systems.
I. Product Overview
The VC60B+ serves as a modern replacement for traditional hand-cranked megohmmeters ("shakers"). It utilizes advanced digital circuitry to provide stable high-voltage outputs and accurate resistance readings. The device features a 45° tilting stand for convenient desktop viewing, overload protection for safety, and a user-friendly rotary dial interface.
II. Key Features & Highlights
-
High Voltage Output & Wide Range
- Selectable Output: Offers four voltage settings (100V, 250V, 500V, 1000V) to test various insulation levels.
- Measurement Range: Capable of measuring insulation resistance from 0.1MΩ up to 2000MΩ (2GΩ), ensuring compatibility with both low-voltage and high-voltage equipment.
-
Safety & Protection
- Overload Protection: Equipped with intelligent anti-burn circuitry to prevent damage from accidental connection to live circuits or excessive voltage.
- Robust Design: Features a durable rubber holster that provides shock absorption and protection against wear and tear.
-
User-Centric Design
- 45° Tilt Stand: The built-in rear stand allows the device to be propped up on a table at an ergonomic angle for easy reading during long tests.
- Clear LCD Display: A large digital screen with a maximum reading of 1999 ensures data is legible even in dim environments.
- Data Hold: Freezes the measurement on the screen for easy recording.
