Features

Comprehensive Measurement Functions: The clamp meter can measure DC voltage, AC voltage, AC current, and resistance, making it versatile for various electrical testing needs.
Auto-ranging Capability: Automatically selects the appropriate measurement range, ensuring accuracy and ease of use without manual adjustments.
Non-Contact Voltage (NCV) Testing: Provides a safe way to detect the presence of voltage without direct contact, reducing the risk of electrical shock.
Overload Protection: Equipped with full-scale overload protection to prevent damage to the meter and ensure user safety during high-load measurements.
Durable and Ergonomic Design: Features a wear-resistant silicone outer shell that offers anti-slip and anti-drop protection, enhancing durability and user comfort.
Backlit LCD Display: The meter comes with a clear, backlit LCD display, making it easy to read measurements even in low-light conditions.
Data Hold Function: Allows users to lock the current measurement reading on the display, making it convenient for recording and analyzing data.

Structure

Tips: Why is the NCV (Non-Contact Voltage) function not detecting voltage?

If the NCV function isn’t detecting voltage, it could be due to the NCV mode not being activated or the sensor being faulty. Ensure that the meter is set to the NCV mode and that the sensor is placed close enough to the wire or electrical source you are testing. If the meter still doesn’t detect voltage, try testing it on a known live circuit to confirm functionality. If the NCV feature fails to work on a live circuit, the sensor might be defective and may require repair or replacement.
