Messages Explanations, causes and problem solutions
already
used !
Cause:
• The selected measuring head has already been started
for a measurement and can only be used for a new
measurement after the current measurement is finished
and the measurement data completely retrieved.
Problem solutions:
• Select new and free measuring head or
• Stop
start or
• Release measuring head (chapter “Maintenance -
Release/reset”)
Set system
clock !
Cause:
Data backup battery was changed!
Problem solution:
Set the clock (see the chapter “GLP/Tools - Settings -
Date/Time”).
defective ! Causes:
The selected measuring head is defective.
Please send it to WTW.
Problem solutions:
• Select new and free measuring head or
• Stop
start
No samples
available !
Cause:
There are no finished samples stored in the sample
management.
Problem solution:
• Transfer the unfinished samples of the sample
management to “finished” status.
To do this, the measurement data of all measuring heads
must be called up and evaluation and documentation of
the measurement data of the finished samples performed.
• If the measurement data of the measuring heads is not yet
finished, no instant remedy is possible!
The memory capacity limit of the instrument has been
reached.
Messages Explanations, causes and problem solutions
No active ! Causes:
• No measurement has been started.
• The measuring heads are placed at another location
(e.g. other levels in the incubator, other incubators,
further storage locations).
• The measuring heads have no optical contact with the
controller:
- Distance too great, angular position imprecise
- IR window of the measuring head averted from the
controller
- Shading by other objects.
• Controller defective
Problem solutions:
• Modification of the distances or angle
• Search other storage locations
• Check controller
• Test the measuring heads (see section
“Requirements/Problems“)
Cal test
due on 18.07.97!
(example date)
Causes
• GLP is switched on
• The test resource monitoring is due within the
measuring time of measurement for the selected
measuring head.
• Date/time is not correctly set in the controller.
Problem solutions
• Use another free measuring head that has been
checked
• Start the due measuring head with the Cal test (see
chapter “Check - Cal test”)
• Switch off GLP and start measuring head (if your
laboratory practice permits).
• Set the date/time in the controller.
