What this tool does

A multifunction automotive circuit tester for 6 V, 12 V and 24 V DC systems. It combines a backlit LCD voltmeter, continuity beeper, polarity LEDs and a piercing probe so technicians can locate shorts, open circuits, bad grounds and voltage drops without repeated disassembly.

Who it suits and who it does not

Ideal for professional mechanics and serious DIYers who need live voltage read-outs, audible overload alerts and one-handed polarity indication in dark engine bays. Not suited for buyers who require AC mains testing, data-logging capability or a non-contact voltage detector.

The spec that decides fit

Measures DC voltage from 3.5 V to 36 V with a stated accuracy of ±0.2 V. If your diagnostic routine demands resolution tighter than that figure, this tester will not meet the requirement.

Questions about this item

How do I connect the power clips to the battery and which probe mode do I select for voltage testing?

Clamp the red clip to the battery positive and the black clip to the negative, then press Up to drive the probe with positive power or Down for negative; the LCD will show live voltage from 3.5 V to 36 V.

What part of the tester will need replacement after repeated wire piercing?

The long sharp probe tip can dull or bend after many piercings, so keep a spare probe or replacement tip on hand for continued accurate contact.

At what voltage does the overload buzzer activate during a sustained short-circuit test?

The buzzer sounds instantly when an overload is detected while probing, protecting both the battery and the tester during continuity checks.
