  • Exceptional Value
Color: Red Black
I wish I’d had this tester a long time ago. The instructions are easy to understand and the tester works exactly as the instructions indicate. I was pleasantly surprised when it was delivered and tester and equipment were all contained in a plastic carrying case. Great value for the price !

  • Prefer to standard multimeter
Color: Red Black
Love being able to diagnose things on my own thanks to the long cord. Saves me tons of time waiting for my husband to het home and works for so many things like being able to find a parasitic draw in our truck

  • Short wire even tho it's long if that makes sense.
Color: Orange Black
Works great as a mobile mechanic however the wires hardly reached from a trunk battery to just inside the engine bay. That I didn't like. Now I need a longer one. And that was a little car. YouTube @Murphys_Mobile_Mechanic_LLC I'll post a review one day.

  • Simple to Use - Bright LCD - Audible and Visual Notifications
Color: Red Black
This is the second circuit tester kit I have purchased. The first one I found very useful in tracking down pesky electrical problems, but usually didn't have it handy when I was traveling and visiting repair shops while at work. So, I bought this ANCEl PB100 Vehicle Circuit Probe Kit to carry with me while the other stays at home. Included in the circuit tester kit were all the items included in the description including: *1 PB100 Circuit Probe *1 Probe Tip *1 Extension Cable (20ft) *1 Set Battery Clips *1 12-Volt Adapter *1 Case *1 User's Manual The PB100 is powered from the battery voltage of the circuit you are testing so no internal batteries are needed. To use you just clip the alligator clips to the source battery or use 12-Volt Adapter and DC Voltage immediately shows on the backlit colored LCD screen. (To verify source voltage just touch the probe to the positive lead of the vehicle's battery or press the toggle switch forward.) Pressing the orange button on the tester toggles between the different functions of the tester. 1) DC Voltage (with a resolution of 0.1 volts) 2) AC Voltage (shows Max. Voltage, Min. Voltage, and frequency) 3) Resistance Mode (Ohm's, for reading resistance between the probe tip and auxiliary ground lead) 4) Diode Mode (for checking forward and reverse bias) There is also a toggle switch that is used to apply source voltage to a circuit (press forward) or provides a direct ground (press backward). I would caution anyone to use extreme caution when using this function as it would be easy to destroy electronic components if used incorrectly. A couple of thing I like about this tester is the two LED work lights on the front come on automatically when the probe is hooked up to a 12-volt power source. This tester also gives you an audible notification when testing circuits along with a visual notification. (explained below) *Red Light / Single Beeps: Near source Voltage is delectated or source Voltage (toggle) is being applied. *Green Light / Mutiple Beeps: Less than source Voltage is detected or a Ground (toggle) is being applied. Overall I like this ANCEl PB100 Vehicle Circuit Probe Kit very much, this type of tester should be part of any mechanic's or electronic tinkerer's arsenal. If I experience any issues I will update this review. ... show more
