Yes. Section 4.7 describes the setup and operation of the DAS system in
detail.
Once per week or as needed. Table 6-1 contains a maintenance schedule
listing the most important, regular maintenance tasks. Highly polluted
sample air may require more frequent changes.
The sample pump should last one to two years and the pump head should
be replaced when necessary. Use the RCEL pressure indicator on the front
panel to see if the pump needs replacement.
If this value goes above 10 in-Hg-A, on average, the pump head needs to
be rebuilt.
There are several possible reasons:
• The wrong cable, please use the provided or a generic "straight-
through" cable (do not use a "null-modem" type cable),
• The DCE/DTE switch on the back of the analyzer is not set properly;
make sure that both green and red lights are on,
• The baud rate of the analyzer's COM port does not match that of the
serial port of your computer/data logger. See Section 7.5.12 more
trouble-shooting information.
