Operating Precautions 
 
The GPT-10000 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.  
The GPT-10000 generates voltages of up to 5kVAC 
or 6kVDC -12kVDC. Follow all safety precautions, 
warnings and directions given in the following 
section when using the instrument. 
1.  Never touch the safety analyzer, lead wires, 
terminals, probes and other connected 
equipment when the tester is testing. 
2.  Do not turn the safety analyzer 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.
