Basic Safety Checks

Background

The GPT-9000/9000A 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).

WARNING

Do not use high voltages/currents when the HIGH
VOLTAGE and RETURN terminals are shorted. It
may result in damage to the instrument.
