Service and Diagnostics Menus
Service Key Descriptions
Alignments
The Alignments Menu allows accessing Diagnostic capabilities of Alignment,
and invoking alignments for individual subsystems.
Diagnostics
The Diagnostics menu contains items for controlling the operating behavior
of Alignment and the Alignment reporting capabilities.
Visible Align
Controls the state of Visible Align. Visible Align replaces the “Aligning
1 or X” messages with descriptive messages describing the
alignment piece begin executed.
Align Log…
(This is not implemented in A.15.xx software)
Invokes Notepad with the Alignment Log loaded. The log can be
viewed or saved to an external media or drive. Notepad can be closed
without a mouse or external keyboard by pressing ALT front-panel
key, then arrow down to highlight Exit, then press Enter.
This file can also be accessed directly on the instrument hard drive
as:
E:\AlignDataStorage\AlignmentHistory.txt
Align Log Mode
(This is not implemented in A.15.xx software)
The Alignment System places information about the last alignment
performed into a log. The log can be configured to operate in clear or
append mode. In clear mode the log only contains information on the
last alignment performed; the log is cleared with each alignment
performed. In append mode each new alignment appends to the log.
In append mode, care must be taken by the operator to not allow the
log to grow to a size so large as to inhibit system operation.
Immediate Actions
The Immediate Actions menu allows invoking individual components of the
internal alignments.
ADC
Immediately executes an alignment of the ADC subsystem. The
instrument will stop any measurement currently underway, perform
the alignment, then restart the measurement from the beginning.
A failure of ADC will set the Error Condition “Align ADC failed”. A
failure will not employ new ADC alignment data.
Successful completion of ADC will clear the Error Condition “Align
ADC failed”.
