After installing an new cuvette the dehumidification system becomes active to remove all
moisture from the ultrasonic transducer. The drying process may last up to 30 minutes, during
this time "DRY" appears in the lower row of the screen and the ultrasonic cleaning cannot run.
Also be aware of the following items:
• The drying process is not an alarm condition and therefore no alarm is active.
• The duration of the process depends on the amount of moisture detected by the
dehumidification system and thus it may vary.
• If you remove the ultrasonic cuvette assembly during the drying process, the message "CLN"
does not appear in the lower row of the display; in the normal case the message indicates
that the spring connection has no contact, but the drying process deactivates this function.
• All seals and the desiccant pack have to be in a good condition (i.e. that the message "DESC"
does not appear in the display); otherwise the dehumidification system cannot function
properly.
• If the drying process is unsuccessful (e.g. because of to much moisture or water on the
cuvette), the message "DESC" appears on the display.
6.2.2 Replacing desiccant pouch and humidity indicator
The device monitors the replaceable desiccant pouch condition continuously. The lower line of
the display shows the message "DESC" in the event that you have to replace a saturated
desiccant pouch that may cause problems. The desiccant has a long lifetime, however its
replacement is necessary from time to time. In this case refer to
Replacing desiccant pouch and
humidity indicator on page 51 and use a new desiccant pouch and humidity indicator.
6.2.3 Replacing the source lamp
The source lamps in the device have a long lifetime. The manufacturer has rated the infrared
lamp for ten years and the white light lamp for seven years.
INFORMATION!
Contact the manufacturer or your local sales office if you need a new, shrinkpacked desiccant
pouch, a new humidity indicator or a new seal.
CAUTION!
To prevent the device from damages, do not try to replace the lamp on your own! If you need to
replace a lamp, contact the manufacturer or your local sales office.
