Product Usage Precautions:
1. This instrument can only be used on de-energized equipment; other equipment can remain energized.
2. The instrument comes with a built-in voltage boosting device; pay attention to the insulation of high-voltage leads and personnel safety.
3. The instrument must be reliably grounded.
4. Before testing equipment with this instrument, perform an insulation test on the equipment first.
5. Determine the voltage withstand level of the equipment and correctly select the voltage boost level of the instrument 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 measurement 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 rolls. In such cases, 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 wire should be grounded; otherwise, a grounding error will be indicated.
