5. Align the filter tape and take up the slack by turning the left (supply) reel counterclockwise.
6. Hold the toggle switch up for about 2 seconds until the Transport LED turns on, then release
the toggle switch to initiate a tape move. Verify that the tape spools correctly. Repeat this
tape advance sequence until the take up spool rotates at least one full turn.
3.8 Starting and Stopping Sample Operation
When 12 VDC power is applied to the unit, the C-12 will boot up and get ready to immediately
begin sampling.
3.8.1 Starting Initial Sample Operations
After powering up and starting sampling, the C-12 takes 1
– 3 hours to warm up and equilibrate
before optimal measurement stability is achieved.
The C-12 carbon monitor is factory configured with an array of default settings that are appropriate
for most sampling requirements. The operator may consider changing some of these settings
depending on specific requirements. See Section 4 for details about the remote user interface and
the instrument settings.
To start a sample when the unit is stopped, hold the toggle switch up for at least 5 seconds until
the green Sampling LED turns on. The transport LED will briefly turn on after 2 seconds. Continue
to hold the toggle switch up until Sampling LED turns on.
3.8.2 Stopping and Resuming Sample Operations
To stop a sample, hold the toggle switch up for at least 5 seconds until the Sampling LED turns off.
After 30 minutes of inactivity, the unit will automatically resume sampling.
