6.7.3 Optical checks
For each optical check, the measured results must be evaluated
against user-specific requirements. The check options do not
define tolerances.
1. Press Optical Checks in the System Checks menu.
The Optical Checks menu contains programs for checking the
wavelength accuracy, stray light and photometric accuracy.
An optional test filter set (Verification Kit) (Section 9 on page 119)
containing 6 precision glass filters, target values, tolerances and
instructions is available and is recommended as an aid for carrying
out comprehensive in-house instrument checks.
6.7.3.1 Wavelength check
The Wavelength Check test is used to check wavelength accuracy
at 807 nm.
1. Press Wavelength Check in the Optical Checks menu.
2. Insert the adapter (A) for 10-mm rectangular cells in the cell
compartment #2 and insert the sample cuvette/cell (Neodym or
BG20/2) in the adapter. Close the cell compartment.
Press Start.
3. The result is displayed and is to be compared with the
nominal/standard data (given in the quality control certificate) of
the sample cuvette/cell.
4. Press Cancel to return to Optical Checks.
