主要特色
Four Probe Modes with an On-Tool Display
電壓測試
Measure the voltage of the circuit under test directly within the supported 9-30V DC range.
Circuit 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.
極性測試
Identify circuit polarity quickly. The green light represents the positive pole, and the red light represents the negative pole.
溫度測試
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.
Four Test Modes
BT210 combines voltage, continuity, polarity and contact temperature testing.
過載保護
Overvoltage and overcurrent protection help protect the tester during supported circuit checks.
Slim Handheld Probe
A 205 × 23 × 18mm body, 1.1m lead and integrated display keep circuit checks within a compact handheld tool.
3年保固支持
主機:三年保固。標準配件:一年保固。保固政策。
服務工作流程
Select the Mode Before Probing
Identify the Circuit
Use the vehicle wiring diagram to identify the conductor, reference point and expected state.
Choose the Mode
Begin with the supported passive voltage, polarity or continuity check and verify the tester range.
Connect the Probe
Make a secure connection without bridging adjacent terminals or damaging the connector.
Run the Selected Check
Do not use this tester to apply power, ground, or a signal output. Follow the component procedure and use only its documented voltage, continuity, polarity, and contact-temperature modes.
Confirm the Finding
Use the observed value to choose the next check; confirm a suspected open, short or component fault at the circuit.
安全使用
Stay Within the Supported DC Circuit
僅限 9-30V 直流
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.
過載保護
When the measured voltage is greater than 30V or measured current is greater than 10A, the tool starts self-protection to help reduce losses.
火花風險
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.
尖銳探針尖端
The probe tip is sharp. Handle carefully during use and storage, and keep the tool properly stored after testing.
利用結果規劃下次檢查
Within the 9–30V DC range, use the displayed voltage, polarity, continuity, or temperature with the circuit diagram and expected operating condition.

電路連接與測量問題
What Voltage Range Can AUTOOL BT210 Test?
BT210 is designed for 9-30V DC vehicle circuits. It is suitable for typical 12V cars, 24V trucks, motorcycles, and other compatible DC vehicle electrical systems within this range.
Can BT210 Be Used On AC Circuits?
No. BT210 should not be used on alternating current circuits, and it should not be used on DC circuits greater than 30V.
What Test Modes Does BT210 Support?
BT210 supports four switchable modes: voltage test, continuity test, polarity test, and temperature test. Press the M key to switch between the four modes.
How Does The Voltage Test Work?
Voltage test is used to measure the voltage of the circuit under test. Use it only within the BT210 rated 9-30V DC range.
How Should I Read The Continuity Test?
Continuity test can detect open-circuit, closed-circuit, virtual circuit, and real circuit conditions. If the indicator light is on, the circuit under test is closed or real. If the indicator light is off, the circuit under test is open or virtual.
How Should I Read The Polarity Test?
In polarity test, the green light represents the positive pole and the red light represents the negative pole.
What Does The Temperature Test Measure?
A temperature sensor is installed at the probe tip to detect the temperature of the designated contact point.
What Happens If The Voltage Or Current Is Too High?
When the measured voltage is greater than 30V or the measured current is greater than 10A, BT210 starts self-protection to help reduce losses. Stop testing and confirm the circuit before continuing.
Why Should I Avoid Flammable Environments?
Sparks may appear on the probe during operation. Do not use BT210 around combustible gas, dust, or flammable and explosive atmospheres.
What Vehicles Is BT210 Suitable For?
BT210 is suitable for cars, trucks, motorcycles, and other compatible vehicle electrical systems, as long as the circuit being tested is within the 9-30V DC range.
BT210 套裝包含哪些內容?
Package contents: BT210 main unit with attached probe and cable, earth clamp / ground connection, user manual, and retail box.
How Is BT210 Different From BT160, BT250, BT260, And BT280?
BT210 is a compact 9-30V DC tester with voltage, continuity, polarity, temperature test, LED light, and about 1.1m wire length. BT160 is more entry-level, BT250 and BT260 add larger display and more measurement ranges, and BT280 adds advanced functions such as relay test, injector test, component activation, oscilloscope mode, multimeter mode, smart test, and online update.
How Should I Maintain And Store BT210?
Do not overload the equipment. Regularly check and tighten connected parts, avoid corrosive liquids, and avoid rubbing the tester against rough surfaces, especially its sheet-metal housing. Store it in a dry, ventilated place away from hot or humid conditions.
