last used is automatically displayed here.
With <> <> you can quickly switch between the ten programs last

To select a program, you can also read in the program number of an
analysis specification with a barcode reader (see section 8.2). The fol-
lowing step 3 is then skipped. You can directly start measurement.
The program number of the test is given in the analysis specification,
on the list of available programs and on the packing of some tests (un-
der the barcode).

enter the required program number with the number keys and
confirm with <START/ENTER>.
