User manual for the ETCR 017AD clamp sensor that measures DC/AC leak currents up to 60 A.
The ETCR 017AD clamp leak current sensor is designed for non‑contact measurement of DC and AC leak currents up to 600 V. Its slim jaws (φ16 mm × 18 mm) make it suitable for crowded wiring environments such as power metering, high‑speed rail, and automotive circuit testing.
The device is powered by a 9 V alkaline battery (6LR61) and offers two selectable output ranges (10 mV/A or 100 mV/A). It includes a ZERO adjustment knob to compensate for external magnetic and electric field interference, and provides a 2 m signal lead with optional BNC termination. This manual is written in Chinese.
