Checking the RPG (Front Panel Knob)
To check the RPG knob:
1.
Press the UTILITY
key.
2.
Rotate the knob and check for a fluid movement of numbers on the
analyzer display.
3.
If the movement of numbers is not smooth or no numbers appear at all,
suspect a faulty A1 front panel interface board. To replace the A1 front
panel interface board, refer to
“Removing and Replacing the A1–A3 and
Other Front Panel Subassemblies” on page 7-10
