Basic Safety Checks 
 
The GPT-10000 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 analyzer is always connected 
to an earth ground. 
3.  Test the safety analyzer operation with a low 
voltage/current output:  
Ensure the safety analyzer 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.
