BT270 Leakage Current Test Clamp

The AUTOOL BT270 is a digital clamp leakage current meter specifically designed for measuring automotive dark current and leakage current. It automatically recognizes AC and DC signals without the need for manual gear switching. It can efficiently measure automotive leakage current, power consumption current, motor starting current, and alternator charging current. This allows you to quickly identify issues such as wiring harness breaks and leakage, electrical component power drain, and ground faults. It is a highly efficient and advanced AC/DC clamp meter.

Working Principle

The AUTOOL BT270 digital clamp leakage current meter utilizes the latest digital integration technology and employs electromagnetic induction to detect AC and DC signals. Its built-in microprocessor processes the signals and converts them into corresponding current values, which are accurately displayed on the HD screen.

Features

Multifunctional AC/DC Clamp Meter: Automatically recognizes AC and DC signals without manual gear switching. It features a clamp-type non-contact measurement method, offering strong anti-interference capability, high precision, compact size, and the ability to accurately measure automotive leakage current, power consumption current, motor starting current, and engine starting current.

Data Storage Function: Supports reviewing historical data with automatic coding for storage, capable of storing up to 99 sets of data.

HD Digital Display: Equipped with a backlight for clear readings in both bright and dim environments.

Easy Operation: Press the Hold/Store/View button during measurement to quickly clear or lock data with one click.

Auto Sleep Function: Automatically powers off after 5 minutes of inactivity, saving energy and extending the clamp meter’s lifespan.

Premium Materials: The clamp meter features a high-insulation shell, ensuring safety and shock resistance.

Wide Application: Widely used in automotive repair, electrical maintenance, industrial equipment servicing, appliance development and more.

Operating Instructions

Note: When measuring AC current, the clamp meter automatically resets to zero. If the “0L” symbol is displayed, it indicates the measured current exceeds the device’s range.

1. Press the power button to turn on the clamp meter.

2. Upon startup, the clamp meter enters DC current measurement mode.

3. Press the zeroing/backlight button to reset the data, then clamp the jaws around the wire to measure.
