- (*) Values are shown for referential purpose. While actual values may vary depending on the type of the
tester; any tester can be used to determine any short-circuit or breakage based on ∞ or several Ω/several
kΩ or 0Ω or ∞.

• Checking procedure for the ISPM
Rectication parts of internal circuit of ISPM (Common)
Remove all the terminals of the ISPM before check. If items (a)
to (h) are performed and the results are satisfactory, ISPM is
normal. Measure it under 1 kΩ range of a tester.
C A U T I O N
• Perform the high voltage discharge procedure as de-
scribed
• Do not use a digital tester.
