Function
A Voltage Absence Tester (VAT) compliant with IEC 61243-3. It is a safety device used primarily to verify that an electrical circuit is de-energized ("dead") before work begins, as well as to check voltage levels, phase sequence, and continuity.
specific applications:
safety Verification (VAT): The CAT IV 600V rating allows logisticians to safely verify "dead" circuits even at the main service entrance or generator output, which is the primary safety procedure before any electrical intervention.
motor Installation: The phase rotation test (Right/Left field) is essential for correctly wiring 3-phase pumps and HVAC motors to ensure they spin in the correct direction.
troubleshooting: The continuity test and single-pole phase detection allow for rapid fault finding in distribution boards and fuses without needing a full multimeter.
