The “unstable” condition may last up to 10 minutes after turning on the machine,
and up to 5 minutes between measurements. If this time is exceeded signifi-
cantly, or if the “stable” condition is no longer reached at all, select the 5HVHW op-
tion from the PDLQWHQDQFH menu.
Check in addition the functionality of the cooler (make sure hot air is coming out
of the outlet). If the “Stable” status is not reached within an additional 30 minutes,
turn the machine off. If the problem persists after the unit has been turned back
on again, please contact your Technical Service Department.

The total number of all measurements that the C 5000 can manage during a run
sequence is limited to about 240. This limitation is reached as early as after 50
hours of continuous operation (25 hours with the duo-control), and the message
above appears. Afterwards, a defined exit must be carried out (menu item (;,7 ).
When you switch on again, normal operation can be continued.
This number has nothing to do with the storage capacity of the library.

Check the O

supply to the unit (30 bar). Check the way the ventilation hose is
installed and laid out. There must be no kinks or obstructions in the degassing
hose. Check the settings in the &RQILJ 6HWWLQJV menu. The 'HFRPSRVLWLRQ item
must not be set, since this turns off O
2
ventilation.
