Features: - Compact Size: Portable to carry and easy to use in one hand. - 36mm Jaw Opening: 36mm large jaw opening allows measurement without touching or interrupting the circuit. - Automatic Range: Enables intelligent and efficient operation for accurate results. - 400A AC Current Measurement: Measures 40A to 400A (2.5%+3), suitable for various wires, providing convenient and accurate readings. - NCV Non-contact Voltage Detection: Detects presence of AC voltage or electromagnetic field. When the clamp head is near a live source, a beep sounds and the NCV indicator flashes. - Data Hold Function: Locks the measured value for easy viewing and recording. - Backlight Function: LCD screen with backlight for clear data visibility in low-light conditions. - Low Voltage Prompt: Displays a low power symbol when battery replacement is needed. Low power may affect measurement accuracy. - Automatic Shutdown: Powers off automatically after 15 minutes of inactivity. - Included Accessories: Comes with 2 pairs of test probes for versatile measurements. Includes a zippered black pouch for storage and portability. - Multifunctional Measurement: Measures AC/DC voltage, AC current, resistance, capacitance, frequency, temperature, NCV, diode, and continuity.
