Chauvin Arnoux CA773 Voltage Absence Tester
The Chauvin Arnoux CA773 Voltage Absence Tester offers electricians a highly reliable and safe method to verify the absence of voltage before working on installations. It is suitable for indoor and outdoor use, and built to withstand tough environments. Designed to meet IEC 61243-3 requirements, it supports testing on 1,000 V CAT IV circuits with confidence.
Clear Display and Efficient Operation
The Chauvin Arnoux CA773 features both LED indicators and a backlit digital screen, allowing for easy reading of voltage measurements in low-light conditions. It supports voltage detection between 12 VAC and 1,000 VAC, as well as 12 VDC to 1,400 VDC. With automatic recognition and a full Autotest system, users benefit from a self-check that covers circuit functionality, power supply, lead condition, and display status.
Enhanced Safety and Additional Functions
Safety is a core strength of the Chauvin Arnoux CA773. The tester includes a flashing ELV LED if voltage exceeds 50 VAC or 120 VDC, offering an additional layer of protection. Phase rotation testing uses a quick and practical 2-wire method, while RCD trip testing features a dual-button operation to ensure hands-on control and user safety.
Designed with convenience in mind, the CA773 also provides continuity testing with both audible and visual indicators. The tester detects stray voltages and includes unipolar phase identification. Optional accessories, including the C.A 753, allow for easier testing of power sockets. This unit is IP65 rated and comes ready to use straight out of the box.
