Autel PS100 12-24V Circuit Tester

The Autel PowerScan PS100 is a handheld circuit tester built for 12-24V vehicle electrical systems. It suits technicians and DIYers who need to diagnose voltage, polarity, continuity and signal circuits on or off the vehicle. The tool also activates components in hand and checks trailer wiring connections. Overload protection is handled by an integrated circuit breaker.

Sustained diagnostic sessions

The integrated circuit breaker prevents overload during extended testing of shorts, open circuits and bad grounds. This allows continuous operation without thermal shutdown when tracing faults across a 40ft combined cable reach. Red and green polarity LEDs give immediate visual feedback during prolonged voltage drop checks. The probe remains operational throughout the full 6-30V supported range.

6-30V DC system limits and 40ft cable reach

The tester is designed for DC vehicle systems between 6V and 30V and does not support AC mains or high-voltage EV architectures. Its 40ft total cable length sets the physical boundary for trailer light testing and remote component activation. Extended data display covers AC/DC voltage, resistance and diode checks within that voltage window. No wireless or network interfaces are included.

Questions about this item

Does the PS100 generate noticeable heat or noise when used continuously on a 24 V system?

The PS100 is a handheld probe with no fan or moving parts, so it runs silently and produces no measurable heat during extended 12-24 V testing sessions.

What power source must I already have to operate the Autel PowerScan PS100?

The tool draws power directly from the vehicle battery or circuit under test — no separate battery pack or mains adapter is required.

Will the 40 ft cable reach around a classic car chassis while I keep using my existing multimeter for reference readings?

Yes, the 20 ft + 20 ft lead set gives 40 ft total reach, letting you probe the full length of a vintage chassis while your multimeter stays connected for comparison.
