Insulation resistance tester BC2010

BC2010 insulation resistance tester is a portable, dual-display pointer-type megohmmeter for on-site insulation testing of cables, motors, generators, transformers, high-voltage switches, arresters and similar electrical equipment. It provides synchronous mechanical-pointer and dot-matrix LCD readout, embedded industrial microcontroller control and a real-time OS for high automation and strong anti-interference performance.

Features

• Selectable DC output voltages: 500 V, 1000 V, 2500 V, 5000 V, with automatic resistance-range conversion (measurement range up to 0–1 TΩ).
• Dual synchronous display: mechanical pointer (ultra-thin tension-wire structure for high vibration resistance) plus dot-matrix LCD for clear observation and operation.
• Integrated mechanical meter head and LCD: dual-scale display, automatic range conversion and color/LED indicators for easy reading.
• Embedded industrial microcontroller and real-time software enabling automated operation and strong anti-interference; automatic calculation of absorption ratio and polarization index.
• User-oriented interface with anti power-off data retention; continuous storage of up to 20 measurement results.
• Audible warning when the instrument generates high voltage and built-in residual HV discharge circuit to automatically discharge tested equipment after measurement.
• AC/DC operation with built-in rechargeable lithium battery and AC adapter for portable field use.
• High-voltage short-circuit current ≥ 3 mA, suitable for testing large transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
• Portable ergonomic design for field deployment.
