Replacing the desiccant
Your camera includes a high-performance molecular sieve desiccant tablet
which is used to avoid condensation in the CCD chamber. Although this
desiccant will last a long time it may eventually need replacement or
recharging, in which case please follow the instructions below:
-
To replace the desiccant, open the desiccant port with the supplied
plastic interface and a screwdriver, take out the used tablet and replace
it with a fresh one. Replace the port cover and tighten (no need to over-
tighten). Wait 24 hours before connecting the camera again.
-
To recharge the desiccant, place the tablet in an electric oven at 200ºC
for a couple of hours. Take it from the oven, wait a few minutes for it to
cool down slightly, then put it back in the camera and wait 24 hours.
Some versions of the 383L+ have a filter inside the desiccant chamber. The
purpose of this is to avoid contamination of the chamber when the desiccant
is being replaced. The filter is very fragile and should not be touched.

Thermal Stabilization
Atik cameras are thermally stabilized in a way that your CCD will output the
best result that it can deliver. This information often appears with the
indication ΔT = -x where x is the cooling capacity. This means that the CCD’s
temperature will drop approximately xº C below outside temperature. This is a
thermoelectric process and therefore in order to obtain the best results you
should wait 2 to 5 minutes until thermal stabilization is achieved (depending
on model). This fact also depends on the outside temperature so, higher
environment temperatures will demand more time for the CCD to stabilize.
