1. The load characteristics are good. The instrument has a stable DC 500V/1000V/2500V/5000V high voltage generator inside.
2. Do not need to zero when measuring. Easy to use and convenient.
3. The timing is accurate. The instrument starts timing while generating high pressure and measuring, so read 15S and 60S,
10m insulation resistance is accurate.
4. Large capacity (large short-circuit current). The absorption current and the charging current are rapidly reduced, and a reliable insulation resistance value is measured.
5. Strong anti-interference ability. Because the instrument uses the single-chip microcomputer as the core, the error caused by the magnetic coupling is eliminated; a filter circuit is further adopted inside the instrument to eliminate the capacitive coupling between the charged device and the device under test. Therefore, the measurement is more accurate.
6. Perfect security measures. After the measurement is completed, the high-voltage output is automatically stopped and a long-time buzzer alerts attention.
