Before You Order And Use

BT280 is an active electrical circuit tester. Confirm the system voltage, selected mode, connection method, and tested component before applying output or activation functions.

Use Only On 9-30V Systems

BT280 is dedicated to 9-30V vehicle electrical systems. Do not use it outside the supported working voltage range.

Confirm Before Activation

Before using component activation, confirm the load, circuit, polarity, and connection method to avoid incorrect operation.

Use 0-5V Output Carefully

Use the 0-5V power supply function only for suitable component wiring verification and follow the voltage setting alarm prompts.

Select The Correct Mode

Choose the correct mode before smart test, multimeter, oscilloscope, relay, injector, polarity, or active component testing.

Check Accessories First

Use the proper probe, test clamp, auxiliary ground lead, relay test port, USB cable, or extension lead according to the test task.

Read The Manual

Download and review the BT280 manual before advanced relay, injector, component activation, 0-5V output, or oscilloscope testing.
