2. Press the measurement items to be calibrated on the CALIBRATION screen.
The CALIBRATION screen for each measurement item is displayed.
Calibration item
[UV/VIS]
Example when the calibration item is UV/VIS:
3. Perform calibration by following the calibration procedure for each measurement item.

Calibration of UV/VIS
There are three kinds of calibration method for UV/VIS: common zero calibration, common span
calibration, and individual span calibration.
Refer to “5.1 Calibration Pattern and its Cycle”
5.4.1
How to Prepare Calibration Solution
Use distilled water for the zero calibration solution, and exclusive calibration solution for the
common span calibration solution.
The calibration solution ampoule (H calibration solution (blue label)) for 1 Abs
(100 m
-1
) is attached to this unit. An attached calibration solution ampoule covers the
measurement range up to 1 Abs. Full scale can be covered from 0.1 Abs to 5.0 Abs (10 m
-1
to
500 m
-1
) by using the 2 or 4 calibration solution ampoules.
Select the measurement full scale you use from the following, and compound the calibration
solution.

Also, our calibration solution ampoule (H II calibration solution (green label)) for 2 Abs (200 m
-1
)
is also available. If using in the measurement full scale of 1.1 Abs (110 m
-1
) or over, it is more
economical to buy H II calibration solution ampoules as the number of ampoules used is fewer.
