How does a stylus work?
1, the first thing to do before using the power tester pen is to calibrate the power tester pen to make sure that the power tester pen is functioning properly. We can test on a known power supply to check whether the neon bubble is luminous. We also need to check whether the power test pen is damp or water, to ensure our own safety.
2, before using the electric tester pen into the electric field test, test the place where the voltage is applicable. Do not try to use the electric detection pen to test the voltage higher than the applicable range, in order to avoid danger.
3, with the power test pen, do not use your hand to touch the front end of the power test pen metal probe to avoid electric shock accidents; Use the power test pen must use your hand to touch the end of the power test pen metal sheet or metal hook. If you do not do so, although the neon bulb of the pen does not glow, but because the charged body, the pen, the human body and the earth does not form a circuit, can not correctly determine whether the charged body is electrified, once the misjudgment will be very dangerous.
4, in the bright light of the use of the test pen should pay particular attention to judge the neon bubble test pen is really bright, many accidents are caused by careless and misjudgment, we must be avoided.
5, the use of the power test pen is best to wear insulating shoes, to prevent the problem before it occurs.
6, judge the same-phase electricity or different-phase electricity, must remember that both feet and the ground must be insulated. Both hands of each pen test, whether both pens are bright or only one bright, are the same. Not bright is the same-phase electricity, as long as the light is different phase electricity.
7, the high-voltage equipment with a power test pen for power test, first of all, must strictly implement the operation of the monitoring system, someone to operate at the same time, a person on the side of the monitoring. The operator should be in front, the guardian in the back. The use of electric test pens, must pay attention to the rated voltage and the voltage level of the electrical equipment being measured fit.
8, check the electricity, the operator must put on insulated gloves, wear insulated shoes, in order to prevent contact voltage injury to the human body. The operator should first in the electric equipment on the inspection of the power test pen. When carrying out electric inspection on multi-layer lines, it is necessary to test the low voltage first, and then test the high voltage, and it is necessary to test the upper layer and then the lower layer.
