Automotive DC Circuit Test Pen, Voltage-Range Options

Check a suitable vehicle DC test point with a handheld voltage indicator. This circuit-test pen suits users selecting the correct range before investigating a compatible electrical circuit.

• ✅ Read a local voltage indication — The digital display provides a reference at the test point.
• ✅ Distinguish polarity — Red and green indicators identify the described positive/negative states.
• ✅ Choose the required range — Separate 6–24 V and 5–90 V versions serve different tasks.
• ✅ Reach around a test area — A spring lead extends within its intended working distance.

Choose the Range for the Circuit Being Tested

Use the correct range and follow the vehicle's service procedure. A test light or pen can load a circuit, so do not assume suitability for sensitive electronic, airbag or communication lines.

The selected model is a DC test tool, not a mains tester or complete diagnostic scanner. Accuracy, input impedance and protection ratings are not confirmed; use it only where its actual specification is appropriate.
