AUTOOL BT270 Clamp On Amp Meter DC Clamp Meter

The AUTOOL BT270 is a compact clamp-on amp meter designed for automotive dark current, leakage current, power consumption current, motor startup current, and generator charging current checks. It supports non-contact AC/DC current measurement, automatic AC/DC recognition, one-button zeroing, data hold, and 99-set data storage for quick electrical fault diagnosis. Review the measurement range, high-voltage caution, zeroing rule, clamp cleanliness, storage environment, battery warning, and maintenance requirements before using the BT270 clamp meter. BT270 focuses on precise current and leakage-current checks with automatic AC/DC recognition, non-contact clamp measurement, one-touch zeroing, backlit display, data storage, and automatic power-off. Use BT270 when you need current-based electrical diagnosis rather than circuit activation or power-probe testing. Power on the meter, zero it correctly, clamp the correct wire, read or store the data, and use fuse-by-fuse checking when diagnosing abnormal quiescent current. BT270 uses non-contact clamp-on measurement with automatic AC/DC shift, 1mA resolution, 99 data sets, CAT III 600V safety classification, and 9V dry battery power. Key features • Leakage Checks: The meter measures DC leakage, AC leakage, ground leakage, and main line current for broader electrical diagnosis. • Auto Identify: AC/DC automatic identification and one-touch zeroing reduce manual setup before measurement. • Non-Contact Clamp: The large clamp is designed for non-contact current measurement, which is more convenient around live wiring. • Product: AUTOOL BT270 Leakage Current Tester Clamp • Measurement Method: Non-contact clamp-on measurement • Range: 0mA-60A AC/DC
