Setting the Analyzer Clock and Time Zone
You can set the Analyzer clock by following these steps:
1. Select the Maintenance tab.
2. Press the Clock button.
3. Press each date component button, enter the appropriate value, and press the Enter
button. Select the Maintenance tab.
4. Press the Clock button.
5. Press each date component button, enter the appropriate value, and press the Enter
button.
6. Press the Menu button, press the Advanced button, and then press the Advanced Setup
button.
7. 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 some 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.
Note:
The Analyzer clock does
not
automatically update for time changes, such as the
change to Daylight Savings Time in the USA.
