Press ENTER to store information selected.
Press ESCAPE to return to RECT DEF and select G02 for
rectifier two.
Configure rectifier number two the same as above and
continue for all rectifiers.
Press ESCAPE to return screen back to main display.
After all rectifiers are configured, proceed to Step 4.
4. On the front of the Galaxy, follow the path:

ENTER and all configured rectifiers will display
their currents, i.e., G01 = 5, G02 = 7, etc.
5. Press ENTER to store and save the information.
Note: Pressing ESCAPE returns the screen one level.
6. With only rectifier #1 on line and carrying a load of
approximately 70 amperes, measure the voltage at test
points E101 and E102 of the 329B fuse board. Calculate
the actual load on rectifier as follows:
The rectifier test points (shunt) will read 50 millivolts at
175 amperes. Each millivolt read on the meter is equal to
3.5 amperes of load. Calculate the load current from this
reading. For example:
20mV x 3.5 amperes per millivolt = 70 amperes
Compare the calculated load current with the current
reading at Galaxy. The shunt reading should agree with the
Galaxy reading. If not, proceed to Step 7. If the two
readings agree, skip to Step 8.
7. Adjust R435 on CM2 of the rectifier to bring the reading
on the Galaxy within tolerance.
8. Repeat procedure for all rectifiers.
