How to use the electric measuring pen accurately
① Before checking whether the electrical appliances and lines are live, you should try it in a place with electricity to see if the test pen is intact, so as to prevent electric shock due to misalignment.
②When holding the pen, press and hold the tail of the test pen with your fingers, and hold the body of the pen with your other fingers.
③ When measuring electricity, the tip of the pen touches the test object, and the hand touches the tail of the test pen. If the test object is charged, the neon tube of the test pen will emit light; if the neon tube does not glow, it means that the test object is not charged.
④ The insulation resistance of the electric measuring pen is less than 1 megohm and cannot be used.
