  • Fantastiv
Was exactly wht i ordered

  • All in one
The Autel PS100 replaces my old test light, AVOmeter, and flashlight—one tool does it all! The 20ft cable reaches tight spots under my truck’s dash, and the tone mode lets me check circuits without staring at the screen. Super handy for parasitic drain checks, too.

  • Perfect Tool
Works great and would buy again

  • Easy to use
Love how simple the 4 modes are: DC voltage checks my battery, AC mode tests the alternator, and the tone feature is very useful in dark areas. It’s durable too—handled hot garage temps no problem. The included clamps and adapter make setup a breeze.

  • Not a good design of tone generator
I don’t usually review things but I thought I should do this time about this power circuit probe #ps100. Every things works correctly but the audio, I mean it’s not a good design just imagine you trying to find a true ignition wire in the car and unfortunately the location isn’t a easy one so you are not able to look at the display you just able to listen to the tune generator of the power probe so you start tapping to the wire which is resting on ground and when you turn a switch to ignition position, you will get the 12 V but if the tune generator gives you a same tune you can not specified the circuit that is change of polarity because a tone stay same until you untap it from the wire and re-tap it then the tone changed which is annoying and it is not supposed to be that way. ... show more
