LI-COR LI-870, Инструкция по использованию

The axes auto-scale, so pay close attention to the axis labels to assess stability. In the
example graph above, the bench temperature, for example, is stabilized within
roughly ± 0.1 °C from the median value/middle of the graph. Once the values have
stabilized like this, you can begin taking measurements following the instructions
in the Smart Chamber or LI-8250 manual.
Storing the LI-870
The post-purge function of the Smart Chamber is designed to allow for ambient air
to flush CO

- and water vapor-rich air from the cable assembly tubing and analyzer
after each measurement. When you are performing your last measurement(s) of
the season, or when you return to the lab or desk after taking your last meas-
urements, you should perform a measurement or two with the Smart Chamber to
allow dry ambient air to flow through your chamber. This will help to remove
humidity before storage.
Note: For more information on post-purge, consult the Smart Chamber manual
or find resources online at licor.com/env/support.
The LI-870 should be stored in non-condensing conditions. If the instrument is
stored in high humidity or moderate humidity for a long time while powered off,
some optical components may temporarily become saturated with humidity. If this
occurs, the instrument may need to run for several days before readings return to
normal. If possible, store the instrument in an air conditioned environment.
