Basic Safety Checks
The GPT-9000 is a high voltage device and as
such, daily safety checks should be made to
ensure safe operation.
1. Ensure all test leads are not broken and are free
from defects such as cracks or splitting.
2. Ensure the safety tester is always connected to
an earth ground.
3. Test the safety tester operation with a low
voltage/current output:
Ensure the safety tester generates a FAIL
judgment when the HIGH VOLTAGE and
RETURN terminals are shorted (using the
lowest voltage/current as the testing
parameters).
Do not use high voltages/currents when the HIGH
VOLTAGE and RETURN terminals are shorted. It
may result in damage to the instrument.
