￭
￭
You can enter the sample data (identification, sample size, etc.) in a variety of ways:
￭
Directly in the main dialog.
Using the sample table. This is particularly useful with sample series.
The sample table is a table in which the sample data for up to 999
samples can be entered (see chapter 21, page 197) .
Automatic request immediately after the start of the determination (see chapter 20.2, page 195) .
You can also send the sample size and the unit from a connected balance in any case. With some balances, the sample identification and method
can be also sent (see chapter 32.5, page 495)
.
20.1 Entering sample data in the main dialog
For a sample, you can enter the sample data directly in the main dialog,
even while the determination is running (see chapter 23, page 208) .
Identification 1
Sample identification. The sample identification can be used in calculations as the variable CI1
. If you have defined a sample identification list (see chapter 15.1.1, page 148)
then the entries can be selected here.

The value will be entered in the corresponding line when the method is loaded. The existing entry will be overwritten.
20.2 Requesting sample data at the start of the determination
The sample data can be automatically requested immediately after the start of the determination in order to ensure that the sample data entry is not forgotten. This automatic inquiry is requisite for reweighing.
900 Touch Control ￭￭￭￭￭￭￭￭ 195
20.2 Requesting sample data at the start of the determination ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
To accomplish this, you must insert and configure the command
REQUEST
in the method (see chapter 29.18.3, page 480) .
If the Hold sequence parameter is activated, then the run will be paused and must be continued with [Continue] after the sample data has been entered. If the Hold sequence parameter is deactivated, then the determination will continue in the background until the measured data is required for further processing. This dialog will be displayed until the entering of the sample data is confirmed with [Continue] , even if the titration/measurement is already completed. This ensures that the sample data is available for calculations.
If a fixed sample size has been defined in the method (see chapter 16.5.3, page 176)
, then it will be displayed at the time of the entry but it will not be editable.

22 Determination run
This chapter provides a description of how to carry out a determination, i.e. how to process a single sample or a sample series. The current sample data is used for calculations.
22.1 Carrying out a single determination
When you carry out a determination, you can enter the sample data in
various ways (see chapter 20, page 194)
. The following instructions describe how to enter the sample data in the main dialog.
To carry out a single determination, proceed as follows:
1 Loading the method
￭
See Chapter "Loading a method", Page 169
.
2 Preparing the sample
NOTICE
Calculate the amount of the sample in such a way that a titrant consumption of 10…90% of the cylinder volume will result.
￭
￭
￭
￭
Weigh in or measure the sample in a sample vessel.
Add solvent.
Place the sample vessel on the stirrer.
Immerse the electrode and buret tip in the solution.
3 Entering the sample size
￭
￭
Tap on the input field Sample size in the dialog.
The number editor opens.
Enter the sample size and confirm with [OK] .
4 Starting a determination
￭
Tap on the fixed key [ ] .
900 Touch Control ￭￭￭￭￭￭￭￭ 205
22.2 Performing a sample series ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
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 common variables are still valid.
– if a sample assignment table is activated (see chapter 15.1.2, page 149)
: whether the entered sample identification is defined in the sample assignment table. If this is the case, then the assigned method will be loaded automatically and the actual determination will be started.
NOTICE
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
[Cancel command] button (NOT with the [ ] fixed key) or with the
[FILL] key on the Manual Dosing Controller. 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 172)
.
Sample table
You can enter the sample data for an entire sample series in the sample
table (see chapter 21, page 197) .

whether the entered sample identification appears in the sample assignment table. If this is the case, then the assigned method will be loaded automatically and the actual determination will be started. If a different method has been entered in the sample table, then it will be ignored.
At the end of the determination,
– the line in the sample table is deleted.
– the next determination is started (if you are working with the autostart function enabled
22.3 Canceling determinations manually
You can cancel a determination at any time with the fixed key [ ] . The command being carried out at that moment is canceled and only calculations and reports are executed or created.
If you are working with the autostart function activated
, the entire series will be canceled.
NOTICE
If you do not wish to cancel the entire determination, but only the current command, use the function [Cancel command] in the live display.
The subsequent method commands are carried out normally.
