Automotive DC circuit tester

The JASTIND 3-72V backlit digital LCD circuit tester is built for automotive technicians and DIY owners who need to verify low-voltage DC circuits on cars, trucks and similar vehicles. It covers a 3-72V range and shows voltage polarity with two colour LED indicators, so the alligator clamp can be connected to either ground or positive. The probe pierces insulation for access to tight or hidden wiring.

Computer-safe LCD readout

A blue backlit LCD gives readings to 0.1 V with an accuracy of ±0.2 V while drawing far less current than an incandescent test lamp, reducing the risk of damaging sensitive electronic modules. The stainless-steel probe is protected by an anti-lost rubber tip that prevents accidental punctures and keeps the tip from being misplaced. The body uses premium acetate fibre for toughness and the 140-inch lead provides generous reach around the vehicle.

Pre-purchase checks

Confirm the vehicle systems you intend to test operate within the 3-72V DC window, as higher-voltage circuits fall outside the tester's range. Ensure you have a suitable DC power source for the unit itself, since it is battery powered. Verify that the probe length and lead reach match the access points on your specific vehicle before ordering.
