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).
