Product Applications
This instrument is suitable for high-precision measurement of contact resistance (loop resistance) in high-voltage switches, and is also applicable to other situations requiring high current and micro-resistance measurement.
Performance Features
1. High Current: Utilizes the latest power supply technology to continuously output high current for extended periods, overcoming the drawbacks of instantaneous current from pulse power supplies, effectively breaking through the oxide film on switch contacts to obtain reliable test results.
2. Strong Anti-Interference Capability: Under severe interference conditions, the last digit of the LCD display remains stable within ±1 digit, ensuring stable readings and good repeatability.
3. Long Service Life: All high-precision resistors are used to effectively eliminate the influence of ambient temperature on measurement results, while the use of military-grade connectors enhances vibration resistance.
4. Portability: Compact size and light weight for easy carrying.
