1)
Connect motor as usual for a HiPot test.
2)
Move Function Knob to 100 μA/div position.
3)
Press start button and ramp voltage up to 5000 volts.
4)
Move Function Knob to the best μA/div range for the observed leakage current.
5)
At one minute, note resistance reading.
6)
Move Function Knob to the 100 μA/div setting and increase voltage to 10,000 volts.
7)
Change μA/div range to best match the observed leakage current.
8)
At the end of the next minute (2 min after start of test), note the resistance reading.
9)
Again, move Function Knob to the 100uA/div setting and then increase voltage to
15,000 volts.
10)
Change μA/div knob to best match the observed leakage current.
11)
At the end of the minute (three minutes after test start) note the resistance reading.
12)
Again, move Function Knob to the 100uA/div setting and then increase voltage to
20,000 volts.
13)
Change μA/div knob to best match the observed leakage current.
14)
At the end of the minute (four minutes after test start) note the resistance reading.
15)
Again, move Function Knob to the 100uA/div setting and then increase voltage to
25,000 volts.
16)
Change μA/div knob to best match the observed leakage current.
17)
At the end of the minute (five minutes after test start) note the resistance reading.
18)
Again, move Function Knob to the 100uA/div setting and then increase voltage to
30,000 volts.
19)
Change μA/div knob to best match the observed leakage current.
20)
At the end of the minute (six minutes after test start) note the resistance reading.
Note:
At each step ramp voltage on the tester in single motions to get the most accurate rise
from one test voltage to the next.
