주요 특징
Clamp-On Current with 1mA Display Resolution
Automatic AC/DC Recognition
The meter automatically recognizes AC or DC signals and switches modes without manual mode shifting for common current checks.
0mA-60A Non-Contact Measurement
Measure AC/DC current from 0mA to 60A with 1mA resolution using a clamp-on, non-contact testing method.
Leakage Current Diagnosis
Supports DC leakage current, AC leakage current, ground wire leakage current, and main line current checks.
백라이트 LCD 디스플레이
The 4-digit LCD screen with backlight helps make current readings easier to see in darker repair environments.
One-Button Zeroing
Press the Zero/Backlight button to reset data to zero before testing. No manual zero-adjustment knob is required.
Data Hold, Memory, And Review
Use the Hold/Mem/Mr button to hold readings and store up to 99 numbered data sets for later review.
자동 종료
After 5 minutes of inactivity, the LCD flashes for 30 seconds before automatic shutdown unless the Power button is pressed to retain the test status.
9V 배터리 전원
The BT270 runs on a 9V dry battery for portable use around vehicle electrical systems and workshop environments.
컴팩트한 클램프 디자인
The integrated clamp, trigger, power button, Zero/Light button, Hold/Mem/Mr button, and LCD are arranged in a compact handheld body.
CAT III 600V Line Rating
The BT270 is marked CAT III 600V for line testing. This safety category is separate from its 0mA–60A clamp-current measurement range; stay within the meter, leads, environment, and procedure ratings.
LCD 크기
The LCD measures 35 × 21.5 mm.

Zero, Clamp and Record Current Changes
단계별 진행 상황1 / 5
01
전원 켜짐
Install a 9V dry battery if needed, then press the Power button to turn the meter on or off.
02
테스트 전 0
The meter starts in DC current mode. Press the Zero/Backlight button to zero first, then clamp the wire. For AC current, the meter can auto-zero; for AC current below 25mA, long press the Power button to switch manually.
03
Clamp The Correct Wire
Clamp the positive and negative DC wires together for DC leakage-current checks, or the live and neutral AC wires together for AC leakage-current checks. Clamp the ground wire alone for ground leakage current, or the main wire alone for the corresponding current measurement.
04
Read, Hold, Or Store Data
Read the current value on the LCD. Press Hold/Mem/Mr to hold and store data automatically; long press Hold/Mem/Mr to review stored data.
05
Diagnose Quiescent Current
Turn off all appliances and set the key to the off position. If quiescent current is too high, pull fuses one by one. A clear current drop after one fuse is removed indicates the corresponding circuit should be checked.
안전한 사용
Respect Conductor, Range and Sleep-State Limits
범위 내에서 유지
Do not exceed the specified measurement range of the instrument. The BT270 is designed for 0mA-60A AC/DC current measurement.
Use Caution Above 60V DC / 30V AC
Operate carefully when the line voltage is greater than 60V DC or 30V AC. Use proper electrical safety procedures.
Zero Before Measurement
Before measuring, press the Zero/Backlight button to perform automatic zero adjustment, especially for DC current testing.
Stop If Safety Is Uncertain
If continued use may create a safety hazard, stop using the meter, isolate it, and contact support or an authorized service provider.
Keep The Jaws Clean
Keep the jaw contact surface clean. Serious contamination can affect measurement accuracy even though the meter has strong anti-interference ability.
Avoid Heat, Humidity, And Sunlight
Do not store the clamp meter for a long time in high temperature, high humidity, condensation, non-ventilated areas, or direct sunlight.
Avoid Impact On The Clamp
Avoid impact on the instrument, especially on the jaw joint and contact surface, because damage may affect testing accuracy.
Replace Low Battery Promptly
Low battery can affect test accuracy. Replace the 9V battery when the battery symbol appears, and remove the battery if the meter will not be used for a long time.
Qualified Maintenance Only
Disassembly, calibration, and maintenance should be performed only by qualified professionals or authorized service personnel.
결과를 활용하여 다음 점검 계획을 세우세요
For current-draw checks, clamp one battery conductor, zero the meter for DC measurement, record the vehicle sleep state, and evaluate the 1 mA resolution with the documented accuracy.

구매자 질문
회로 연결 및 측정 관련 질문
무엇인가 AUTOOL BT270 Used For?
BT270 is used for automotive dark current, leakage current, power consumption current, motor startup current, generator charging current, ground wire leakage current, and main line current checks. It is a clamp-on current draw tester, not a power-probe circuit activation tool.
Does BT270 Automatically Recognize AC And DC?
Yes. BT270 can automatically recognize AC or DC current and switch modes without manual mode shifting for common testing. For AC current below 25mA, long press the Power button to switch manually.
What Is The Measuring Range And Resolution?
The BT270 measuring range is 0mA-60A AC/DC with 1mA AC/DC resolution. If the LCD shows OL, the measured current is over the maximum test range.
Should I Zero The Meter Before Measurement?
Yes. Press the Zero/Backlight button before measurement to perform automatic zero adjustment. The meter starts in DC current mode after power-on. For AC measurement, the meter can auto-zero, but zeroing before general testing is still a safe operating habit.
Can BT270 Measure Automotive Quiescent Current?
Yes. Turn off all vehicle appliances, turn the key off, allow the vehicle to reach the sleep state specified by its diagnostic procedure, and make sure the clamp is fully closed during testing. Typical quiescent current may be about 30-40mA, while some European vehicles may be about 80-90mA depending on vehicle class and installed equipment. Use the vehicle’s specified limits when judging the reading.
What Should I Do If Quiescent Current Is Too High?
If tested quiescent current is 100mA or above after the vehicle reaches the sleep state specified by its diagnostic procedure, electrical leakage may exist. Open the fuse box and pull fuses one by one. If the current drops clearly after one fuse is removed, check the corresponding circuit or appliance, repair the issue, and test again.
Can BT270 Replace A Power Probe Circuit Tester?
No. BT270 is mainly for clamp-on current measurement and leakage-current diagnosis. If you need polarity testing, continuity testing, jumper lead operation, component activation, relay testing, diode testing, or power-probe functions, compare BT160, BT210, BT250, BT260, and BT280 before ordering.
What Power Supply Does BT270 Use?
BT270 uses a 9V dry battery. Replace the battery promptly when the low-battery symbol appears, because low battery can affect measurement accuracy. Remove the battery if the meter will not be used for a long time.
