5. Touch [+] of the tester to [P] of DIP-IPM (soldered part), and
[-] to DIP-IPM U, V, W terminals to measure the resistance.
Normal if all three terminals have 1 kΩ or greater.
6. Contrary to [5], touch [-] of the tester to [P] of DIP-IPM
(soldered part), and [+] to DIP-IPM U, V, W terminals to
measure the resistance
. Normal if all three terminals have 30 kΩ or greater.
(Resistance gradually increases during measurement.)
7. Touch [-] of the tester to [N] of ISPM (soldered part), and [+]
to ISPM U, V, W terminals to measure the resistance.
Normal if all three terminals have 1 kΩ or greater.
8. Contrary to [7], touch [+] of the tester to [N] of DIP-IPM
(soldered part), and [-] to DIP-IPM U, V, W terminals to measure
the resistance.
Normal if all three terminals have 30 kΩ or greater.
(Resistance gradually increases during measurement.)
1. Tester.
2. Contact with specified terminals to measure.
Non-faulty if [9] – [13] are checked and satisfied.
(Measure with 1 kΩ range of a tester.)
