Preparing a tester in the analog system is recommended.
A tester in the digital system with diode check function will
be usable.
Perform the following procedures prior to check.
(1) Power Off.
(2) Remove all the wiring connected to the PC board where power transistors are mounted on.
[Preparation]

Tester
[Point of Measurement and Judgment Criteria]
·
Measure the resistance value using a tester at each point of measurement below, 10 minutes later after power OFF.
To use analog tester:
Measurement in the resistance value mode in the range of
multiplying 1kΩ.
To use digital tester:
Measurement is executed in the diode check mode. ( )
