7 MAINTENANCE
The calibration gas bottle is designed to provide
approximately 80 sampling operations (45 for
B-Lac). The following message will alert the
operator that the gas bottle needs to be changed
(Fig. 7-21).
To change the gas bottle:
1. Press
<New Gas Bottle> .
2. Unscrew the gas bottle by turning the knob on
the bottom counterclockwise.
3. Take a new gas bottle and remove its cap.
4. When prompted (Fig. 7-22), scan the new gas
bottle bar code on the insert sheet by holding it
2-3 inches (5-8 cm) from the bar code scanner
on the bottom right-hand corner of the analyzer.
• The red line from the barcode scanner
should cover the entire barcode.
• The analyzer will beep when the barcode is
accepted.
• Record the date of installation on the gas
bottle for later reference.
NOTE: If the insert sheet is misplaced, you can
enter the lot number on the gas bottle label
manually. Press <Manual> (Fig. 7-22) and
enter the number using the numeric keypad.
NOTE: The bar code contains expiration
information. The OPTI CCA-TS2 will alert
the operator four weeks before the gas bottle
expires.
NOTE: The gas bottle should always be stored with
the cap on.
5. When prompted (Fig. 7-23), install the new gas
bottle.
6. Insert the bottle into its housing and turn it
clockwise until finger-tight (Fig. 7-24).
