Ground Down Conductor Continuity Resistance Tester Power Facility Features
1. Power technology: Adopts the latest power technology, outputs 10A current, can work continuously for a long time, overcomes the drawbacks of instantaneous current in pulse power supplies, and obtains good test results.
2. Strong anti-interference capability: Under severe interference conditions, the last digit of the LCD screen can stabilize within ±1 digit, with stable readings and good repeatability.
3. Long service life: All high-precision resistors are used, effectively eliminating the influence of ambient temperature on measurement results, and the use of connectors enhances vibration resistance.
4. Simple operation: Just press the measurement key to get the measurement result. The measurement result is displayed with LCD backlight, with intuitive readings and good repeatability.
5. Easy to carry: Adopts portable design, small size and light weight. The panel and chassis are integrated, with good shock resistance.
