• Checking procedure for the ISPM
Rectification 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
described
• Do not use a digital tester.
