900 Touch Control
Sequence of the determination
￭ After a determination is started, a check is made as to
– whether all of the devices required are connected and ready for
operation.
– whether all titrants and sensors are present.
– whether the monitoring intervals for titrants, sensors and com-
mon variables are still valid.
– if a sample assignment table is activated (see Chapter 15.1.2,
page 147):
whether the entered sample identification is defined in the sam-
ple assignment table. If this is the case, then the assigned
method will be loaded automatically and the actual determina-
tion will be started.
NOTE
Manual titrations (MAT command):
Start of titration: Because of the technical implementation involved, a
few microliters are already dosed at the start of a manual titration. The
possibility of deviation from the actual endpoint volume is excluded,
however, because the already dosed volume is taken into account.
End of titration: A manual titration must always be ended with the
button [Cancel command] (NOT with the fixed key [
]). This is the
only way to ensure that subsequent method commands will be carried
out.
22.2 Performing a sample series
You can use the following functions with sample series:
￭ Statistics for multiple determinations
The statistics calculations are enabled in the method options (see
Chapter 16.5, page 170).
￭ Sample table
You can enter the sample data for an entire sample series in the sam-
ple table (see Chapter 21, page 195).
