The correct way to use the test pencil:
1. Before testing whether electrical appliances and lines are live, you should test them on a live place to see if the test pen is in good condition, in case of misjudgment and electric shock.
2. When holding the pen, press the tail of the test pen with your fingers, and the rest of your fingers can hold the pen body.
3. When measuring electricity, the tip of the pen touches the test body, and the hand touches the tail of the electricity measuring pen. If the test body is charged, the neon tube of the test pen will emit light; if the neon tube does not emit light, it means that the test body is not charged.
4. The insulation resistance of the electric test pen is less than 1 megohm and cannot be used.
