3.7.2 DIAGNOSTIC AID ACTIONS

Diagnostic Aid Actions enable the operator to visually monitor or verify suspected
problem areas. All of the Diagnostic Aids, except Command Code 0, are used only
in bench calibrations and tests.
A. Display Errors - Command Code 0
The red status indicator on the front panel is ON when an out-of-tolerance
(error) condition occurs, and turns OFF when the error condition ends. Refer
to Error Code Table 3-3 for possible error causes and solutions.
The amber status indicator on the front panel is ON to indicate that the error
condition has been entered into the computer error memory, even if the error
no longer exists. The amber indicator remains ON until the operator clears
the memory list. The computer will acknowledge this command even if the
"Enable/Disable" switch is in the "Disable" position.
Command Code 0 displays the list of errors in memory in numerical
sequence. Press CLR to acknowledge and clear an error from the memory
list. The computer automatically advances the display to the next error
number.
When the error conditions no longer exist, and when all of the error codes
in the memory list have been acknowledged, the amber status light turns
OFF.
