Images are for illustration purposes only. E&OE Overview The CT8002 is a computer safe, all solid state electronics circuit tester. Unlike regular test lights, this high-impedance circuit tester is safe to use around automotive computers, electronics, ecm’s, sensors and air bags.Rugged, built to last and simple to use, it requires no wire or clip connector to ground. The CT8002's LED, sound and vibration indicators, allow users to check for power in less time that it takes to set-up a regular test light and find a suitable ground, and is designed for use in automobiles, trucks, tractors, trailers, RV’s, motorcycles, boats and any DC powered circuit from 3 to 28 volts. Features No Ground or clip requiredNo ground wire means no wire tangles nor time lost searching for grounding pointsHigh Impedance Electronic circuitrySafety V-groove needle accessory for piercing and carryingNegligible current draw ( 20 micro-amps) is 10,000 times less than regular lamp type testers. This gives complete safety when working around sensitive electronic control modules and sensorsOperating range between 3 and 28 Volt DC in battery powered systems.Buzzer & LED Indicator gives audible and visual signal when positive voltage is detected, making it ideal for reaching congested places.Buzzer vibration indicates even when used in noisy out-of-sight locationsProfessional rugged stainless steel metal construction is damage resistantInsulator body molded in chemical resistant plasticSolid State lamp for lifetime lasting performanceLong-life alkaline batteries installedAvailable in Red, Blue, Yellow and Black Specifications Input impedance : 1Mohm Minimum input impedance (approx. 20 micro-amps @ 24 Volt).Input Voltage : 3 to 28 Volts.
