Operating Precautions
Background The GPT-9000/9000A is a high voltage
instrument that outputs dangerous voltages.
The following section describes precautions and
procedures that must be followed to ensure that
the tester is operated in a safe manner.
WARNING
The GPT-9000/9000A generates voltages of up to
5kVAC or 6kVDC. Follow all safety precautions,
warnings and directions given in the following
section when using the instrument.
1. Never touch the safety tester, lead wires,
terminals, probes and other connected
equipment when the tester is testing.
2. Do not turn the safety tester on and off quickly
or repeatedly. When turning the power off,
please allow a few moments before turning the
power back on. This will allow the protection
circuits to properly initialize.
Do not turn the power off when a test is
running, unless in an emergency.
3. Only use those test leads supplied with the
instrument. Leads with inappropriate gauges
can be dangerous to both the operator and the
instrument.
For GB testing, never use the Sense leads on the
SOURCE terminals.
4. Do not short the HIGH VOLTAGE terminal
with ground. Doing so could charge the chassis
to dangerously high voltages.
