Product usage precautions:
1. This instrument can only be used on de-energized equipment; other equipment may remain energized.
2. The instrument comes with a built-in voltage boosting device. Pay attention to the insulation of the high-voltage lead and personnel safety.
3. The instrument should be reliably grounded.
4. Before using this instrument to test equipment, perform an insulation test on the equipment first.
5. Determine the voltage withstand level of the equipment and correctly select the instrument's voltage boosting gear to prevent breakdown of the equipment and damage to the instrument.
6. Although the dedicated high-voltage cable supplied with the instrument has passed inspection at the factory, it should still be kept away from the human body during measurement.
7. The input voltage is AC220V±10%. Exceeding this range may affect the test accuracy. The maximum input voltage is AC264V. Exceeding this value will cause permanent damage, and the manufacturer will not provide warranty for such damage.
8. The printer may experience paper jams during transportation due to loose paper roll. In such case, simply remove the paper roll, tighten it, and reinstall it.
9. The instrument should be protected from moisture and severe vibration.
10. When powered by a generator, the output neutral line should be grounded; otherwise, a grounding error will be indicated.
