DC voltage highest tested: 2500VPolarity test: 3V-36V,Voltage test: 50-500HzOverall Length: 140mmTip Width: 3.5mmHandle diameter: 16mmFeatures:With indicator light, can measure breakpoints, move along the contact, when the indicator does not light was breakpoint, can measure the line whether is electrified, the non-contact sensor test, safe and reliable.2. The self-test function:Usage: When using self-testing sign in one hand and take the tip in one hand touches the touch electrode3. Line On / off detectionUsage: first-hand contact pin zero line, the other hand on the electric pen touch pole, written contact pin FireWire.phenomenon:On: indicates that the loop line is normal, there is no line breakage.Unlit: line marked off here somewhere, did not turn on. Line-off detection: electrician maintenance staff are widely used in rice cookers, computers, washing machines and other daily household electric plug line testing equipment.4. Test Power outageClutch electric pen tip and tail hand touch very close to or in contact with the wires, check the lights off along the wire instructions here breakpoint.5. Zero FireWire judgmentUsage: electric pen tip in direct contact with the measured object, such as a written test flapper need to touch the inside of the copper pieces.Phenomenon: FireWire: Light-emitting diodes light illuminatesZero line: Light-emitting diodes does not light or a little shimmer6. Sensing functionClutch electric pen tip and tail hand touch very close to or in contact with the sample, we can observe the internal light emitting electric penPackage included:1x Electrical Tester Pen
