4. INSTALLATION / SETTING UP
Preliminary inspection
Unwrap the spectrophotometer, take off the involving plastic and take off the protec-
tion in which it comes fitted. Take off all the protective items and, without connecting the
spectrophotometer to the net, make sure that it does not present any damage because of
the shipment. In case the spectrophotometer presents any damage tell it immediately to
your transport agent or dealer so that they can make the claims in the correct time limit
Please keep the original wrapping; you will always need it for returns enclosed with all
the accessories supplied.
Please check that all the accessories are enclosed with the equipment:
- Schuko cable
- 4 glass cells
- Cable USB
- Software MWave Basic
- User’s manual
- Warranty

Put the sample of unknown concentration into the light path and its concentration
value will be automatically displayed.
3. Concentration calculation by coefficient adjustment mode (Fig. 3) .
This mode allows the calculation of concentration of different samples using the equa-
tion of a known concentration curve according to the following formula:
By pressing Mode
(1.1)
select the coefficient adjustment mode (F)
Input the value of the coefficient K by pressing ▼ ▲ (1.3) (1.4 ); the selection range goes
from -1999 to 1999.
Press Enter (1.2) to save the selected value.
Input the value of the coefficient b by pressing ▼ ▲ (1.3) (1.4) ; the selection range goes
from -1999 to 1999.
