Multimeter wire piercing probes are made of high-quality material, resistant to cold and high temperatures, and more flexible to use. The spring loaded double "V" clamp fixes the wire at the center of the piercing needle. Voltage: 30VAC/60VDC, current: 5A. Therefore, it ensures safe use in various environments, including manufacturing, commercial, electrical, and engineering applications. Firstly, turn the thread to unscrew the probe, adjust the spring clip to clamp the probe onto the wire to be measured, then insert the multimeter probe or 4mm banana head into the tail socket, and finally measure the voltage with a voltmeter. Suitable for equipment maintenance, electrical maintenance, and automotive maintenance. This can help you easily and efficiently complete wire testing voltage testing.
