3
calibration gas for
several hours prior to calibration.
12. Perform a NO
X
span calibration (refer to section 5.4)

2.4 Transporting/Storage
Transporting the Serinus should be done with great care. It is recommended that the packaging the
Serinus was delivered in should be used when transporting or storing the instrument.
When transporting or storing the instrument the following points should be followed:
1. Turn off the instrument and allow it to cool down.
2. Remove all pneumatic, power and communication connections.
3. If storing over a long period (six months) turn the battery off by switching the DIP switch (S1) on
the main controller PCA (refer to Figure 9).
4. Remove the instrument from the rack.
5. Replace the red plugs into the pneumatic connections.
6. Remove the USB memory stick and pack with instrument (refer to Figure 8).
7. Place the instrument back into a plastic bag with desiccant packs and seal the bag (ideally the bag
supplied upon delivery).
8. Place the instrument back into the original foam and box it was delivered in. If this is no longer
available find some equivalent packaging that provides protection from damage.
9. The instrument is now ready for long term storage or transportation.
Note: After transport or storage, the instrument must be set-up and calibrated
(Refer to Section 2.3.4).
