Check the condition of your car battery by measuring its internal resistance, without discharging it. Also track shorts and measure with high accuracy all kinds of low resistances: shunts, PCB tracks, contact resistances, relays, chokes and various windings, RTD sensors, etc.

This instrument is based on an AC low current very low frequency 4-wire resistance+ inductance measurement technique, which solves the issues of DC measurement errors. And it has the ability to measure the internal resistance (+ voltage) of DC current sources, with optional DC bias.
There are 4 measuring ranges from 1 up to 1000 ohms (best resolution of 10 microohms) with manual or automatic selection.
Powered by a standard 9V alcaline battery.
