Test Light Automotive Voltage Tester With 12V 5W Bulb Circuit Tester 5V-30V Fuse Tester Led Digital Test Light With Dual Probes,45"Test Wire Polarity Tester For Cars,Motorcycles,Trucks,Trailers Etc.

DUOYI #ad - Voltage polarity display&load device measurementin the measurement, the positive/negative polarity of the power supply can be measured by using red/green light-emitting diodesred light positive, green light negative. Polarity tester has two probes, combined with the main probe, you can use the auxiliary probe, for the load plug, to directly perform load simulation measurement. It can also check whether the power cord is energized or whether the negative power cord in the plug is properly grounded.

With a bright led digital voltage display, test plugs, which can be used to pierce wires and reach narrow areas, can quickly detect the short/open circuit of the circuit, the voltage can be read clearly and accurately whether it is day or night. Test bulb has high visibility, sensors, can be detached and replaced, and can be directly replaced with a car bulb select 12V5W. Three working modes can be switchedtest light automotive has a switch and a 12v 5w test bulb, battery fault/fuse circuit diagnosis, to complete voltage test, and judge the voltage intensity by testing the brightness of the bulb higher voltage:max 30V, or either the LED digital display and the bulb work Computer safe mode/bulb mode, you can select the LED digital display and the bulb to work at the same time quick test mode through the switch, brighter bulb:max 5W.

Bulb load measurement&voltage measurementuse the 5w test bulb on the top of the voltage tester as the load to quickly determine the power failure of the line. Compared with the diode, and the brightness and darkness of the electric pen bulb, can realize more accurate measurement, it can also find some invisible poor contact and virtual voltage failures. In addition, using the voltmeter function of the electric pen, it can perform pure voltage measurement, thus improving the level of fault diagnosis. Stainless steel probe&led digital display&detachable test bulbthe test pen has two probes made of pure steel, relay sockets etc.
