Safety, Operation, and Procedure Instructions for the PFT Series of 

AC Hipots 

Danger- Lethal Voltages:  

Equipment to be used by trained personnel only 

This Operator Manual contains instructions for the operation of a High Voltage power source. The operator of this equipment 

must use good judgement and follow all safety precautions noted in this guide to ensure the protection of himself and others in 
close proximity to the test area. 

Failure to follow the instructions could result in injury or 

death. Proper grounding of the test set must be done prior to connecting this unit 
to a power source.
