Before You Order And Use

BT260 is a low-voltage automotive electrical tester. Confirm the operating range, measuring range, current limit, power connection, and overload protection before testing vehicle circuits.

Vehicle Low-Voltage Use

Use BT260 on compatible 12V and 24V vehicle electrical systems within its 9-30V operating voltage range.

Measurement Range

The tester supports 0-65V DC voltage, 0-65V AC voltage, and 0-200kΩ resistance measurement.

Rated Current

The specification image lists a 1-10A rated current. Keep jump-wire and circuit checks within the proper rated range.

Overload Protection

Current overload protection can automatically disconnect the tester during overload or short-circuit conditions to help reduce circuit risk.

Power Connection

BT260 is powered through the vehicle battery clamps or the cigarette lighter adapter shown in the package image; no internal battery is required.

Stay Within Rating

Do not use this tool on circuits outside its rated range, and do not treat it as a high-voltage EV battery or household mains tester.

Safe Testing Reminder

Use the probe, auxiliary ground clamp, battery clips, and cigarette lighter adapter only as intended.
Correct a short circuit or overload condition before continuing the test.
For high-current motors or starter-related circuits, test the control circuit and stay within the BT260 rated current range.

Product Comparison

Compare BT260 with other AUTOOL automotive circuit testers before choosing the right operating voltage, measuring range, cable length, display, language support, and advanced functions.

BT1606-24V operation, basic circuit checks, 4m power cable, no screen, and no multi-language interface.

BT2509-30V operation, 0-65V DC / AC measurement, 0-200kΩ resistance measurement, TFT color display, 9 languages, and 1.5m cable.

BT260BT250-level voltage and resistance test coverage, plus a longer 12m power cable for front-to-rear vehicle electrical inspection.

BT280Higher-end option with 0.1-100V DC / AC measurement, 0-18A current range, larger 320×240dpi display, 14 languages, oscilloscope, multimeter, smart test, online update, relay test, and advanced component activation functions.

Decision CheckChoose BT260 if you need a 9-30V automotive circuit tester with 0-65V measurement, resistance and diode modes, TFT display, 9 languages, and a 12m cable instead of advanced BT280-only functions.

Key Features

BT260 combines multi-mode electrical testing, long-cable vehicle coverage, color display reading, LED lighting, overload protection, and multi-language operation for common automotive circuit diagnostics.

Multi-Mode Circuit Testing

Supports DC voltage, AC voltage, resistance, diode, continuity, polarity, grounding, and signal circuit checks for common vehicle electrical diagnostics.

DC Voltage Testing

Measures DC voltage with 0.1V resolution and ±0.2V accuracy, helping check voltage values at different circuit nodes.

AC Voltage Testing

Detects maximum and minimum voltage values, supply frequency, and duty cycle of the circuit under test.

Resistance And Diode Modes

Measures resistance from 0-200kΩ and helps check diode working status, continuity, and open-circuit conditions.

12m Front-To-Rear Cable

The 6m + 6m power cable setup helps cover the full length of larger vehicles for front-to-rear electrical circuit inspection.

Color Display And Lighting

A 1.7-inch TFT color screen and 2 LED flashlights on the probe head help improve reading and visibility in darker work areas.

9 Language Options

Supports English, Russian, German, French, Simplified Chinese, Polish, Italian, Spanish, and Portuguese.

Powered By The Vehicle

Connect through the vehicle battery or cigarette lighter adapter shown in the package image, without needing a separate internal battery.

Warranty And Support

AUTOOL provides 3-year support for eligible non-human damage cases, with assistance for setup, accessories, model selection, and troubleshooting.

Applications

Use BT260 to assist common low-voltage vehicle electrical troubleshooting, including circuit status checks, poor-ground detection, continuity checks, and long-distance inspections on larger vehicles.

Circuit Fault Checks

Helps identify open circuits, continuity issues, short circuits, poor grounding, and faulty circuit connections.

Lighting And Socket Checks

Useful for checking headlights, taillights, faulty sockets, fuses, wires, and related low-voltage circuits.

Relay And Switch Checks

Supports switch, relay, polarity, grounding, signal circuit, continuity, and jump-wire style checks under proper conditions.

Wide Vehicle Coverage

Suitable for compatible cars, motorcycles, trucks, excavators, boats, RVs, and other 12V / 24V vehicle electrical systems.
