8)

Continue to press and hold Test button. In the screen’s center, the tester will acquire 

and display a Leakage Current Reading at 3 minutes. This is used for the DA calculation. 

The DA ratio will also appear.  

9)

After 10 minutes of continual testing, the tester will automatically acquire and display 

the leakage current. The PI ratio will be automatically calculated and displayed.  

10)

Continue to press and hold Test button, and turn Function knob to 100uA/div position. 

11)

Ramp test voltage to desired DC over voltage test value (HiPot test voltage). 

12)

Change μA/div setting as required to obtain best current readings (follow instructions on 

screen).  

13)

After time required to hold HiPot test voltage has elapsed (usually 60 seconds), release 

Test button. The leakage current readings upon button release are displayed in the 

center of screen.
