Instrument Usage Precautions
1. Do not touch the high-voltage connection line or the cable under test during testing to avoid injury from high voltage;
2. Do not turn on the instrument while connecting the cable, and turn off the power immediately after the test;
3. The instrument cannot be started when the voltage adjustment is not at zero;
4. At least two people should be present during use. One person connects the wires, and the other checks them. The test can begin only after everything is accurate;
5. The instrument's grounding terminal must be reliably grounded. Use a dedicated grounding wire, preferably clamped to grounding posts in the test field, grounding bars in electrical cabinets, or the feet of mechanical equipment.
