You can measure real samples without preceding routine measuring work:

 if measuring breaks last less than 2 hours.
Measuring real samples without preceding routine measuring work
Please observe the following instruction:
Caution Inserting multiple samples into the ball valve (only for
solid operation)
If there are samples in the carousel while you are changing the position of the
carousel via System > Sample Position, multiple samples may fall into the ball
valve at the same time. In this case, a service technician is required.
Before changing the position of the carousel, always remove all samples from the
carousel.
Proceed as follows:
 Move the empty carousel to zero position. To do so, open the "Set carousel position" dialog in
the operating software by selecting System > Sample Position.
 Select the radio button next to "Reference run" and click OK. The carousel moves to zero
position.
 Prepare the samples. Cf. Sample preparation instructions (on page 126).
 Insert the samples on the carousel.
 Enter the weight in [mg] in the sample view (text view) on the PC if it has not already been
transmitted online by the balance.
 Enter the sample name (max. 32 characters) in the sample view (text view).
 Select a suitable method. See Values for oxygen dosing (on page 137).
 Go through the measuring start checklist. See Checklist for real sample measurement (on
page 142).
 Start the analysis process in the operating software:
 Select System > Auto run to start a multiple-sample analysis.
 Select System > Single run to start a single-sample analysis.
 Once measurement is finished, evaluate the measurement.
 Save the data or print them out. See Data backup and printing (on page 158).
