5-90V Digital LED Circuit Tester

The KEHIPI 5-90V Digital LED Circuit Tester is an electrical system tool for automotive diagnostics. It provides voltage readouts on a clear digital display with 0.1V resolution and ±0.2V accuracy. The tool includes an extended spring wire reaching 110 inches and a large alligator clip for flexible one-hand operation. A bidirectional LED indicates polarity with red for positive and green for negative.

Automotive technicians and DIY owners

This tester suits users who need a portable voltage display and polarity indication for fuse checking and circuit tracing on vehicles. The spring wire extends the reach for measurements across the engine bay or chassis. Buyers who require data logging, waveform capture or continuity beeper functions should look at dedicated multimeters or oscilloscopes instead. The tool does not offer those capabilities.

110 inch spring wire reach

The single specification that decides fit is the maximum extended length of the spring wire at 110 inches. This determines whether the probe can reach test points from the chosen ground location on a specific vehicle. If the working distance exceeds this length, the tool cannot make the connection. Verify the required reach against this figure before purchase.

Questions about this item

What comes in the box with the KEHIPI tester and what must I supply myself?

The unit includes the digital LED circuit tester with an integrated 110 inch spring wire, an alligator clip and a protective insulation cover. No separate accessories are mentioned.

How do I decide between the available versions or capacities of this tester?

The product is offered as a single 5‑90 V model with 0.1 V resolution and ±0.2 V accuracy; no alternative voltage ranges or capacities are listed.

What does the 0.1 V resolution and ±0.2 V accuracy mean when I use the tester on a vehicle circuit?

The display will show voltage in 0.1 V steps and the reading will be within ±0.2 V of the true value, while the bidirectional LED indicates polarity with red for positive and green for negative.
