Description:

The C.A 773 voltage tester is an essential tool for electricians to safely check the absence of voltage in circuits, devices, or installations.
Compliant with IEC standard 61243-3, Edition 2, it is approved for all installations up to 1000 V CAT IV, indoors and outdoors.

The C.A 773 combines LED indicators with a backlit digital display for precise measurement readings.
A redundant safety system includes a blinking ELV LED warning light that signals voltages above 50 VAC / 120 VDC.
The integrated self-test ensures proper functioning of circuits, power supply, indicators, and test leads.
Phase rotation is determined via a microprocessor using only two leads.

Additional features of the C.A 773 include:

• RCD trip threshold testing with two-hand operation.
• Optical and acoustic continuity testing, extended to R < 0.5 Ω to 2.999 kΩ.
• Detachable test tips and leads for versatile applications.
