4. DC voltage highest tested: 2500V
5. Polarity test: 3V-36V
6. Voltage test: 50-500Hz
7. Overall length: 140mm
8. Tip width: 3.5mm
9. Handle diameter: 16mm

Features:
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 electrode
3. Line on / off detection
1）Usage: first-hand contact pin zero line the other hand on the electric pen touch pole written contact pin firewire
Phenomenon:
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 judgment
1）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 illuminates
3）Zero line: Light-emitting diodes does not light or a little shimmer
6. 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 pen
7. 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 pen
