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 large current and micro-resistance measurement.
Performance Features
1. High Current: Using the latest power supply technology, it can continuously output large current for a long time, overcoming the drawbacks of instantaneous current in pulse power supplies, effectively breaking through the oxide film on switch contacts, and obtaining good test results.
2. Strong Anti-interference Capability: Under severe interference conditions, the last digit of the LCD screen can remain stable within ±1 digit, with 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, and the use of military-grade connectors enhances vibration resistance.
4. Easy to Carry: Small size and light weight.
