SYSTEM DIAGNOSTICS AND MAINTENANCE
SYSTEM MESSAGE TABLES AND OTHER TROUBLESHOOTING TOOLS
2) The log entry includes the date and time of the event, the name of the Operator
logged in, and the name of the error message posted.
3) The Alarms and Errors log saves entries for up to one year.
4) Prior entries to the log are deleted on a “first in, first out” basis as the capacity
is exceeded.
b. To add comments to an entry, click on the entry and then on the
Add Comments
button.
3. Help the trainee locate the error message tables under
Heading 11.14 SYSTEM ERRORS in
the Online Help System or the Instructions for Use manual.
a. The message table is an alphabetized list of the error and system messages generated
by the instrument.
b. The table includes the probable cause of each message and the action to take.
Troubleshooting Using Special Procedures
1. The reproducibility check shows how close several results (from the same specimen) are
to each other; in other words, this check measures repeatability or precision.
a. Reproducibility does not measure accuracy, but true accuracy is not possible unless
the instrument is precise.
b. Doing a reproducibility check before doing a calibration procedure might catch
imprecision problems that could affect the calibration process.
2. Carryover is the interaction of the previous sample with the current sample.
3. If either reproducibility or carryover are out of specification limits, it could adversely
affect the data.
a. These procedures are discussed under Heading 4.6, REPRODUCIBILITY AND
CARRYOVER CHECKS, in this Training Guide.
b. The procedures for checking reproducibility in either the Manual mode or the
Autoloader mode, are covered under H
eading 11.8 REPRODUCIBILITY CHECK, in the
Online Help System or the Instructions for Use manual.
Troubleshooting Using Instrument Diagnostics
1. The instrument has several diagnostic functions that allow you to check the Analyzer’s
hardware.
2. From the Main Menu screen, click tt tt to access the (Users
Diagnostics) Hardware Systems screen.
a. This screen has five tabs.
1)
Hardware Reset
2) Motors
3) Valves
4) Sensors
5) Autoloader Test
b. The options accessed by these five tabs allow you to check the instrument hardware.
