説明
Electricity Does Not Announce Itself. A shorted harness, a corroded ground, a relay that only fails once it is warm. Faults like these consume hours with a multimeter, because a meter reports a value without telling you where the circuit went wrong. The PowerScan PS100 answers the real question. It identifies positive, negative and open circuit instantly, and it traces a short to the physical place it occurs.
Built around the diagnostic workflow. Read voltage, current and resistance at the fingertip, check continuity across switches, relays and diodes without dismantling anything, and confirm a bad ground contact in seconds instead of after a lap of the vehicle. Relay component testing happens in circuit, and the unit runs from the vehicle battery at 12 or 24 volts, so there is no internal cell to charge before a job.
Protection included. A circuit-breaker-protected input means an accidental probe across a live circuit ends with a reset rather than a repair bill. The TFT colour display at 160 x 128 dpi keeps a numeric readout legible in workshop light, and the analogue display behaviour turns a fluctuating signal into visible movement rather than a blur of changing digits.
A tool for the diagnostic bay rather than a component for the toolbox. The kit arrives with the carrying case, clamps and probes needed on the first day, so it is a complete instrument rather than something you then have to accessorise before it can be used.
Any meter can measure a circuit. This one tells you where it broke.

Where the Circuit Cartographer Works
It lives in the diagnostic bay of a workshop, the toolbox of a mobile auto electrician, and the van of anyone who installs aftermarket wiring. Marine and agricultural mechanics use it on 24 volt systems where a misdiagnosed ground turns into a return visit. Fleet operators run it as a pre-delivery check, because tracing a parasitic drain with this tool takes minutes rather than an afternoon.
Frequently Asked Questions
Q: Does it need batteries?
A: No. It draws power from the vehicle battery at 12 or 24 volts, so there is nothing to charge before a job begins.
Q: What faults can it diagnose?
A: Open circuits, positive and negative identification, short circuits, bad grounds, and continuity across switches, relays and diodes. Relay testing is performed in circuit.
Q: What is included in the box?
A: The tester itself, a carrying case, clamps, probes and a user guide.
Q: Is it protected against my own mistakes?
A: The input is circuit-breaker protected. An accidental probe across a live circuit trips the breaker instead of destroying the unit.
Q: Will it work on a 24 volt truck?
A: Yes. The unit operates on 12.0 or 24.0 volts supplied by the vehicle battery.
Q: Is this the genuine Autel tool?
A: Yes, it is the Autel PowerScan PS100, current 2025 hardware revision, supplied with the standard accessory kit.
Q: Is it worth buying alongside a multimeter?
A: A multimeter tells you a value. This tells you where the circuit failed, which is the part of the diagnosis that consumes the time.
Q: Can it be used on a hybrid or electric vehicle?
A: It works on the 12 volt and 24 volt systems these vehicles still use for lighting, body control and ancillaries. Do not probe the high voltage traction system.
Q: Does it come with a manual?
A: Yes. A user guide is included in the carrying case alongside the clamps and probes, and it documents the measurement modes plus the breaker reset procedure.
Q: What warranty applies?
A: Tell us your market before ordering and we will confirm the warranty terms that apply, along with the correct plug and accessory configuration for your region.
Q: Will the clamps damage insulation?
A: The supplied clamps and probes are the standard accessory set for this tool. For delicate harness work, back-probe at the connector rather than piercing the insulation.
