10. When "A1" shows on the display, measure the absorbance of the
reacted standard solution.
a. Insert the reacted standard sample cell in the cell holder.
b. Install the instrument cap over the cell holder.
c. Push
d. Remove the sample cell from the cell holder.
11. The calibration is completed with two calibration points. If additional
standards are necessary for calibration:
a. Push
b. Do steps
12. Push two times to go back to measurement mode.
Enter a calibration curve with the keypad
At least two data pairs are necessary to enter a user-prepared
calibration curve. A concentration value and the absorbance value for
the given concentration is necessary for each data pair. A maximum of
10 data pairs can be entered.
Note: This procedure can also be used to change the data pairs in a user-
entered calibration curve.
1. Set the instrument to the range to calibrate. Refer to
instrument on page 11.
