Nickname: Megohm Meter; insulation resistance test equipment
Features
1. The insulation resistance tester has multiple voltage output options of 500V, 1000V, 2500V, and 5000V. The measurement range of resistance can reach 0-1T Ω, and the resistance range can be automatically converted with corresponding indications.
2. Two methods of synchronously displaying insulation resistance values. The mechanical pointer adopts an ultra-thin tension wire structure with strong seismic resistance. The use of mechanical pointers can easily observe the range of insulation resistance changes, and the use of dot matrix LCD screens can guide users in operating instruments and accurately obtain measurement results.
3. The mechanical meter head is integrated with the LCD screen. Dual scale display, automatic range conversion. The color scale is easy to read and has LED display of corresponding colors.
4. Adopting embedded industrial microcontrollers and real-time operating software systems. High degree of automation and strong anti-interference ability, the instrument can automatically calculate absorption ratio and polarization index without manual intervention.
5. The operation interface is friendly, and various measurement results have anti power off function, which can continuously store 20 measurement results.
6. When the instrument generates high voltage, there is a prompt sound output.
7. Built in residual high-voltage discharge circuit, which can automatically discharge the residual high-voltage on the tested equipment after the test.
8. AC/DC dual-use, equipped with rechargeable battery and AC adapter.
9. The insulation resistance tester adopts a portable design, which is easy to operate in the field.
10. High voltage short circuit current≥ 3mA 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.
