Before You Order And Use

Before You Order And Use

BT210 is designed for vehicle DC circuit troubleshooting. Confirm voltage range, circuit type, working environment, and tool condition before testing.

9-30V DC Only

Use BT210 only on 9-30V direct current vehicle circuits. It is suitable for typical 12V car and 24V truck electrical systems within this range.

Do Not Use On AC

Do not use BT210 on alternating current circuits. It should not be used on DC circuits above 30V.

Overload Protection

When the measured voltage is greater than 30V or measured current is greater than 10A, the tool starts self-protection to help reduce losses.

Spark Risk

Sparks may appear on the probe during work. Do not use the tester around combustible gas, dust, or flammable and explosive environments.

Check Tool Condition

Stop using the tester if the instrument body or test lead is damaged. Check and tighten loose connected parts before operation.

Sharp Probe Tip

The probe tip is sharp. Handle carefully during use and storage, and keep the tool properly stored after testing.

Maintenance Notes

  • Do not overload the equipment or use it outside the rated range.
  • Avoid rubbing the product against rough surfaces, especially the sheet metal housing.
  • Regularly check parts that need to be tightened or connected.
  • Avoid contact with corrosive liquids.
  • Store the product in a dry place; do not store it in hot, humid, or non-ventilated areas.
Key Features

Key Features

BT210 provides four switchable detection modes, a built-in probe light, digital display, polarity indication, continuity indication, overload protection, and compact operation for vehicle electrical maintenance.

Voltage Test

Measure the voltage of the circuit under test directly within the supported 9-30V DC range.

Continuity Test

Detect open-circuit, closed-circuit, virtual circuit, and real circuit conditions. Indicator on means closed or real circuit; indicator off means open or virtual circuit.

Polarity Test

Identify circuit polarity quickly. The green light represents the positive pole, and the red light represents the negative pole.

Temperature Test

A temperature sensor at the probe tip detects the temperature of the designated contact point.

Probe Light Function

After power-on, the light turns on by default. Press the Lighting key to turn the light beside the probe on or off.

Portable Vehicle Use

Designed for convenient vehicle troubleshooting on compatible cars, trucks, motorcycles, and other DC vehicle electrical systems.
