you do not plan to use WETView or a WET Labs data logger, consult the Data
Processing
section of this manual for a detailed description of the binary data format.
RS-232:
Operating across an RS-232 cable, you can obtain binary data from the
instrument. If you are using WETView, read the operational instructions contained in the
software manual.
2.4 Care and Maintenance
Built for field deployment, the ac-s requires minimal maintenance. However, following
these simple recommendations will assure optimum data integrity as well as longer
instrument life.
After a field deployment of the ac-s you should clean the instrument prior to storage.
Refer to
Section 1.4 for detailed cleaning procedures. The following steps will help
prolong the life of the instrument:
1.
Rinse the pressure housing.
If a dummy plug for the connector is available, install it
on the main bulkhead connector before flushing the instrument. Begin with a
thorough rinsing of the unit and its flow tubes with fresh water. After rinsing, towel-
dry the pressure housing and remove the flow tubes.
WARNING!
Do not use acetone on the windows. It will damage the window holders.
2.
Wash the windows.
The windows should be cleaned with dilute soapy water,
followed by ethyl alcohol, and should receive a final rinse with distilled or reverse
osmosis-filtered water. This will remove any fingerprint oil, grease or other
contaminants from the windows. Use lint free lens cleaning paper to avoid scratching
the windows or detectors.
3.
Wash the flow tubes.
To clean the absorption path’s reflective tube, carefully plunge
an alcohol-soaked tissue through the tube and rinse thoroughly with distilled water.
Whenever plunging a tissue through the tube, use a wooden or plastic dowel to
prevent scratching the sides of the tube. After rinsing, dry the tube either by blowing
dry nitrogen through it or by plunging a soft tissue. The attenuation path flow tube is
virtually maintenance free, except for occasional cleaning. Follow the same basic
procedures supplied for cleaning the absorption path tube. Remove the flow tube
sleeves when drying the flow tubes.
4.
Store the meter.
Store and transport the ac-s in a shock-protected environment.
Typically, units are shipped in a sturdy wooden crate. Using the crate will assure that
you can safely transport the instrument, providing it is handled in a reasonably careful
fashion.
