4.15 Diagnostics
4.15.1 Moduleware Run-Time Diagnostics
The PDA-100 Moduleware periodically checks the status of certain
system parameters. Minor problems that do not justify stopping operation
are reported to the host computer and recorded in the Audit Trail. The
Audit Trail includes the date, time, and error code for each problem the
PDA-100 reports. There are two ways to review this information:
•
Check the Audit Trail displayed in the PDA-100 control panel,
or
•
Retrieve the Audit Trail from a sequence by selecting the Audit Trail
folder and the file for that date.
4.15.2 Software Diagnostics and Calibration
PeakNet 6 and Chromeleon contain comprehensive diagnostics for the
PDA-100. This section briefly describes some of these diagnostics; for a
full description, refer to the software Help or user’s manual.
