The screen returns to the UV/VIS CAL. screen.
CAUTION
• The decimal place of the input range varies according to the setting in “6.5.2 Setting of
Decimal Place for each Component”.
• Refer to “5.4.1 How to Prepare Calibration Solution” for the concentration value of
compounded span calibration solution.
• If performing either one of the calibrations, set the span calibration value to “0” for the
component that is not being calibrated. By doing this, the span calibration for single
component becomes possible.
9. Press the button for [SPAN VALUE] for VIS on the UV/VIS CAL. screen.
10. Enter the concentration value of compounded span calibration solution with the numeric
keypads, and press [SET],
Input range: 0.000 Abs to 5.000 Abs or 0.0 m
-1
to 500.0 m
-1
The screen returns to the UV/VIS CAL. screen.
11. After waiting for 3 minutes and confirming that the measurement value is stabilized, press
[SPAN].
The “Start span cal.?” screen is displayed.
12. Press [YES] to start the span calibration.
The “Calibrating” screen is displayed.
After calibration, the “Calibration finished” screen is displayed.
13. Press [YES].
The span calibration value for UV/VIS is updated.
14. The common span calibration is finished.
If performing another span calibration subsequently, start the span calibration with the
detector still in the calibration tank.
If finishing the calibration, set the detector in the measuring tank.
CAUTION
Do not reuse the calibration solution used in the calibration tank. The accuracy of calibrated value
may be lost.
