Specification:1. Testing range: 70-250V2. AC voltage contacts test range: 70-250V3. AC voltage without contact test Range: 70-600V4. DC voltage highest tested: 2500V5. Polarity test: 3V-36V6. Voltage test: 50-500Hz7. Overall length: 140mm8. Tip width: 3.5mm9. Handle diameter: 16mmFeatures:1. Waterproof function. Completely invade the water, can be use after dry.2. Usage: when using self-testing sign in one hand and take the tip in one hand touches the touch electrode3. Line on / off detection1）Usage: first-hand contact pin zero line, the other hand on the electric pen touch pole, written contact pin firewirePhenomenon:1）On: indicates that the loop line is normal, there is no line breakage.2）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 outage, clutch 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 judgment1）Usage: 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.2）Phenomenon: FireWire: Light-emitting diodes light illuminates3）Zero line: Light-emitting diodes does not light or a little shimmer6. Sensing function，Clutch electric pen tip and tail hand touch very close to or in contact with the sample, we can observe the internal light emitting electric pen7. 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.Package included:1x electrical tester penSpecification: Package Weight One Package Weight 0.11kgs / 0.25lb One Package Size 20cm * 5cm * 5cm / 7.87inch * 1.97inch * 1.97inch Qty per Carton 262 Carton Weight 30.00kgs / 66.14lb Carton Size 50cm * 50cm * 60cm / 19.69inch * 19.69inch * 23.62inch Loading Container 20GP: 177 cartons * 262 pcs = 46374 pcs 40HQ: 412 cartons * 262 pcs = 107944 pcs
