5.2 100% adjustment of the photometer
Recalibration of the photometer can change the readings slightly from the
previous ones, because the instrument is reset to a reference standard (e.g.
distilled water)!
Before the 100% adjustment is started, the photometer must have reached the
operating temperature (UV > 2h/LED > 10 min)!

appears in the display. If that occurs,
check the following points:

Ensure the device is properly mounted

The measuring cell may be too dirty
 Ensure the correct zero medium is used

In the UV range (254nm, 313nm) distilled water is used as zero medium; in
the visible range (365..700nm) either clear, colorless water or any colorless
sample else is normally adequate enough.
