Operating Instructions
Warning:
•
To avoid electric shock, always de-energize power before entering an electrical enclosure.
•
Always follow safety and lockout/tagout procedures when working on or near electrical systems and equipment.
•
Use proper
personal protective equipment (PPE) when working around sources of hazardous electrical energy.
•
Absence of voltage is indicated by illumination of the green Absence of Voltage Indicator. Absence of voltage is not
guaranteed when the red Voltage Presence Indicators are not illuminated.
The AVT should only be operated by individuals who have been trained on the operation of the tester and can demonstrate
knowledge of the following criteria:
•
Familiar with requirements and information in the Instruction Manual and understand the function of the AVT,
meaning of the indicators and markings, and limitations of the Voltage Presence Indicators
•
Aware of where the AVT is installed in the electrical system and any additional electrical hazards that may be
present in the system that are not detectable by the AVT
•
Able to recognize electrical hazards and familiar with lockout/tagout procedures
Voltage Presence Indicators
A.
When voltage is detected in one or more phases, the appropriate
Voltage Presence Indicators will illuminate.
B.
Absence of voltage is not guaranteed when the Voltage
Presence Indicators are not illuminated
. To test for absence of
voltage, push the Test Button.
A.
B.
Absence of Voltage Test
Each time the Test Button is engaged, the absence of voltage test sequence will be activated. The test
sequence includes running a self-check, using a known voltage source to test the tester to verify that
the AVT is functioning, testing for AC and DC voltage phase-to-phase and phase-to-ground, and
verifying the sensor leads are in contact with the circuit conductors.
1.
De-energize the circuit according to company safety procedures.
2.
Verify that lockout/tagout devices have been applied to all applicable energy sources and the
Voltage Presence indicators are not illuminated.
3.
Press the Test Button to initiate the absence of voltage test.
4.
The Caution Indicator will begin to flash. This indicates that the test is in progress.
5.
When the absence of voltage is verified, the Absence of Voltage Indicator will illuminate.
6.
If the absence of voltage is not verified, the Caution Indicator will illuminate for about five
seconds followed by a series of flashes. The number of flashes will help diagnose why the test
failed. Refer to the Troubleshooting section for additional information.
