II. M2 Input Check
This measurement is performed under energy.
The red probe of the multimeter should be in contact
with leg 1 shown in Figure-2 and the black probe
should be in contact with leg 9. 10V value is observed
here if the M2 is not active. This value decreases to 8V
when the M2 is active.
III. M3 Input Check
