Description in English:

The C.A 771 two-pole voltage tester is an essential tool for electricians to safely and reliably check voltage absence in circuits, devices, or installations. With its CAT IV 1000 V protection class, IP65 rating, and extended climate class S, it is suitable for demanding indoor and extreme outdoor conditions.

Key Features and Functions:

• Maximum Safety:
- CAT IV 1000 V protection for maximum security.
- IP65 rating for rugged environments.
- ELV warning LED signals voltages > 50 VAC / 120 VDC.

• Advanced Functions:
- Voltage detection up to 1000 V AC / 1400 V DC.
- Single-pole phase detection for quick tests.
- Phantom voltage recognition.
- RCD trip testing up to 30 mA with two-hand operation.
- Microprocessor-controlled phase rotation detection with only two leads.
- Continuity testing with acoustic and optical indication, including extended testing for R < 2 kΩ, 60 kΩ, and 300 kΩ.

• High Flexibility:
- Detachable test tips and leads.
- Two clip positions for test tip spacing of 16 mm or 19 mm.

• Enhanced Climate Resistance: Operates under temperatures from -30 °C to +60 °C (Class S).

Technical Data:
