Each time the instrument is powered up, a series of diagnostic tests are performed automatically to ensure operation of major system components. This procedure, which takes approximately two minutes, checks the system, lamp, filter adjustment, wavelength calibration and voltage. Each test which functions correctly is confirmed with a check mark. If the instrument detects any deviation relative to the last calibration, a system check has to be carried out.

Remove the cuvette from the cell compartment and close the lid. Then press Start. Note: Further error messages during self check, see Section 8 on page The entire screen is touch-activated.
