Press ENTER; the display will now show
RECT 01
TYPE: UNCONFIGURED (flashing)
SHUNT mV: 50.00
MAN SW: NONE
Press or - to scroll through menu until
J87132B-2 appears in TYPE.
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.

Press
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. Remove insulator from battery of BJH3 circuit pack.
7. With only rectifier #1 on line and carrying a load of at least
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
