The smart dual-display insulation resistance tester adopts an embedded industrial microcontroller real-time operating system, combining an ultra-thin tension wire meter head with a graphic dot-matrix LCD display. This series of meters has multiple voltage output levels (500V, 1000V, 2500V, 5000V), large capacity, strong anti-interference, simultaneous pointer and digital display, AC/DC dual use, simple operation, automatic calculation of various insulation indicators (absorption ratio, polarization index), and various measurement results with power-off protection. This series of smart dual-display insulation resistance testers is an ideal testing instrument for measuring the insulation resistance of large-capacity transformers, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
Features:
1. Multiple voltage output options (250V/500V/2500V/5000V), (5000V/10000V), with a resistance measurement range of up to 0～400GΩ.
2. Two methods synchronously display insulation resistance values. The analog pointer allows easy observation of the change range of insulation resistance, while the digital display provides measurement results.
3. Adopts embedded industrial microcontroller and real-time operating software system. High automation, strong anti-interference capability, the instrument can automatically calculate absorption ratio and polarization index without manual intervention.
4. User-friendly interface, various measurement results with power-off protection, can continuously store 19 measurement results.
5. When the meter generates high voltage, there is a prompt tone output and corresponding display.
6. Built-in residual high-voltage discharge circuit, after testing, it can automatically discharge the residual high voltage on the tested equipment.
7. AC/DC dual use, configured with rechargeable battery and AC adapter.
8. The meter adopts a portable design for easy field operation.
9. High-voltage short-circuit current ≥3mA, it is an ideal testing instrument for measuring the insulation resistance of large transformers, transformers, generators, high-voltage motors, power capacitors, power cables, lightning arresters, etc.
