Usage Notes
1. Only use on de-energized equipment;
2. Built-in booster: ensure HV lead insulation and personnel safety.
3. Must be properly grounded;
4. Check equipment insulation before testing.
5. Confirm withstand voltage, select correct boost range to prevent damage.
6. Keep HV cables away from personnel and LV test leads during testing.
7. Input voltage: AC220V±10%. Operation outside this range may affect test accuracy. Max input: AC264V. Exceeding this causes permanent damage not covered by warranty.
8. If printer jams due to loose paper during transport, remove paper roll, rewind tightly, reinstall.
9. Protect from moisture and vibration;
10. Ground output neutral when using generator power, otherwise a grounding error will be indicated;
