MENU CALIBRATION PROCESS
14. Preliminary Instructions
a. The procedures in paragraphs 15 through 22 should be performed only if an out-of-
tolerance condition exists in paragraphs 8 through 12 or if an error message on the bottom
line of the crt display is:
TEST 04 XX
where XX is 01, 02, 10, or 11 when POWER pushbutton is pressed to ON.
b. When performing paragraphs 19 through 22, touch only specific control or controls
called out in the procedure. Movement of any other control may cause erroneous
calibration results.
c. Within the automatic calibration procedure, the calibration constants for timing,
vertical gain, and trigger level are generated by the system microprocessor and stored in
nonvolatile memory. The adjustments in CAL 01, 02, 03 should be done in numerical sequence.
d. When performing automatic CAL steps, initial setting of front-panel controls is not
required.
15. Equipment Setup
WARNING
HIGH VOLTAGE is used or exposed during the performance of
this calibration.
DEATH ON CONTACT may result if
personnel fail to observe safety precautions.
REDUCE
OUTPUT(S) to minimum after each step within the
performance check where applicable.
