5.2.1 Tube tests
MACHEREY-NAGEL tube tests can be selected in different ways with the
spectrophotometer. All test tubes are labeled with a barcode. When the start
screen is active or the device is in measuring mode, the barcode of the inserted
test tube will be scanned automatically. The instrument detects the tube test and the
measuring process is initiated automatically (
Please note: tube tests which need to be
measured against a zero solution cannot be measured automatically using the barcode ).
After the measurement has been completed, the measurement result will be displayed in the
result window (figure 20).

Via and the icons below the result window, different sample information can be added.
Via the “Properties” command, new sample information can be added below the
measurement menu. For this purpose, the desired icon in the opened dialogue must be held
down and then dragged into the blue flashing sample information bar with a wiping motion.
(Please note: If the icon is already present in the sample information bar, this option is not
available. ) To remove the icon from the sample information bar, the procedure is similar. This
time the icon must be removed from the blue flashing sample information bar with a wiping
motion after holding it down. The following sample information can be added to the sample:

Sample number: Sample numbers are assigned automatically and consecutively by
the instrument. By pressing the sample number icon, you can assign a sample
number manually. Thereafter, the instrument will count forward based on the
manually assigned sample number.

automatically.
