Do not touch the test lead during a withstand voltage withstand voltage
test or insulation resistance test.
A hazardous voltage is applied to the measurement terminals during the test. Doing

Do not touch the metal area to which a voltage is applied until the
DANGER lamp turns off.
After the test ends, the test voltage may still remain in the test target. Touching the
metal areas with the voltage applied may cause electric shock accidents.
