Missing beaker
(SAC error) Beaker not detected. Solve the problem and restart the sequence
from the beaker it stopped (key 1 Resume analysis).
Warning!
Do not change the turntable before restarting the sequence from the
beaker it stopped (key 1) or before restarting the sequence from the
next beaker (key 2). The sample changer identifies a turntable only
when a new sequence is initialized (equivalent to a keystroke on 3
End of sequence followed by 1 Run sequence).
Causes:
1. There is no beaker at the dedicated position and/or there is not
enough liquid in the beaker and the beaker cannot be detected.
Refer to "Beaker detection minimum height", page 51 .
Add solution in the beaker or desactivate the beaker automatic
detection by clearing the option "Beaker detection" in
TitraMaster 85 (refer to TitraMaster 85 on-line help, topics "Edit-
ing an application - Configuration").
2. Using a level, check that the sample changer is installed on a flat
and horizontal bench surface.
3. If points 1 and 2 have failed, adjust the beaker detector position
(refer to the User’s Guide of the sample changer, chapter 6
"Maintenance").
Missing EP This message shows that the end point has not been reached for the
titration before the Maximum volume.
Missing IP This message appears at the end of an inflection point titration when,
the number of IP’s detected is less than the number of IP’s entered in
the Method parameter menu.
Refer to "Number of IP", page 126 .
Mode This is the type of method used.
