IMPORTANCE
- When measuring insulation resistance, ensure that the two test probes are placed separately and not twisted together.
- Do not short-circuit the two test probes and the high-voltage output before measuring insulation resistance.
- Do not perform measurements if the battery cover is opened.
ATTENTION
- Before testing, ensure that the circuit to be tested is de-energized; do not measure the insulation of energized equipment or lines.
- After testing, do not touch the circuit as stored capacitance can cause electric shock.
- Do not touch the test leads connected to the circuit until the test voltage is fully discharged.
