Introduction Testo 750-3 – Digital Voltage Tester
The Testo 750-3 can perform GFCI Circuit tests on AC outlets. When performing a GFCI circuit test, a 35 mA load is applied to the circuit. The testo 750 vibrates ensuring that the GFCI circuit test is active.
In addition to the above features, the Testo 750-3 includes a 3-digit LCD showing the actual voltage measurements. Also, it includes an RCD trip function for safely and easily testing residual-current devices.
The Testo 750-3 Digital Voltage Tester are the first instruments to include an all-around viewable LED voltage indication, ensuring visibility from any angle and making it easy to read measurements in various lighting conditions.
Designed for durability and reliability, the Testo 750-3 meets CAT III 1000 V CAT IV 600 V safety standards and can withstand tough working environments. Audible and visual alerts enhance safety and usability, making this voltage tester a versatile and reliable tool for professionals. It features vibration feedback when voltage is detected, adding an extra layer of safety and confirmation for the user.
The device is capable of three-phase sequence testing, essential for verifying proper connection and functionality in industrial applications.
