5. If you want to set the time zone as well, press the Back button, press the Advanced button, and then
press the Advanced Setup button.
6. Press the Time Zone button, and specify the time zone via the two buttons on this screen. Note that the
time zone information you enter here does not modify the time to which you set the clock in Step 3.
• Time Zone — Allows you to set a text descriptor for the time zone. Usually this is a three-letter code,
such as “EST” for Eastern Standard Time or “GMT” for Greenwich Mean Time.
• GMT Difference — Allows you to enter the offset from Greenwich Mean Time. Use the number pad
and the +/- button to specify the offset. For example, for Eastern Standard Time you should enter
-
5.00

Reviewing Warnings and Errors
The Analyzer issues two levels of messages:
1. Warnings — Warnings do not stop TOC measurements, but may indicate that corrective action is
required to prevent eventual Analyzer shutdown or loss of data.
2. Errors — Errors are serious alerts and all errors stop TOC measurements to prevent the collection of
erroneous data or to protect the Analyzer from damage. Corrective action should be taken before the
Analyzer can resume normal operation.
Warnings and errors issued by the Analyzer collect in the Warnings/Errors list after their initial display. The W
icon displays in the Menu screen header when a warning has been issued and the E icon displays when an error
has been issued; if both a warning and an error have been issued, then the E icon will display, as errors are more
serious alerts than warnings. (See Chapter 8: Troubleshooting for additional information on warnings and
errors.)
To display the Warnings/Errors list, follow these steps:
1. Select the Maintenance tab.
2. Press the Warnings/Errors button.
3. Use the scroll buttons to browse through the warnings and errors. The Analyzer displays the date, error
number, error description, a brief suggestion for corrective action, time of last occurrence, and the
number of times this warning or error has occurred. A complete listing of warnings and errors, along
with corrective actions, is given in “Warnings and Error Messages” on page 154.
4. Press the Acknowledge button for each error and warning to clear the error/warning status of the
instrument and automatically reset the alarm(s).
Note:
The Analyzer clock does
not
automatically update for time changes, such as the
change to Daylight Savings Time in the USA.
