5. When "S0" shows on the display, push . Push to enter the
concentration value of the first data pair, then push .
Note: Push to go to the next digit.
6. When "A0" shows on the display, push . Push to enter the
absorbance value of the first data pair, then push . "S1" shows on
the display.
7. Do steps 5–6 again to enter the second data pair (S1 and A1).
8. The calibration is completed with two data pairs. If additional data
pairs are necessary for calibration:
a. When “Add” shows, push .
b. Do steps 5–6 again to enter more data pairs.
9. Push two times to go back to measurement mode.
Remove a calibration point
To remove a calibration point from a user-entered calibration curve:
1. Set the instrument to the range to calibrate. Refer to Configure the
instrument on page 11.
2. Push and hold until "USER" and then "CAL" shows.
Note: If "USER" and "CAL" do not show, the factory calibration cannot be
changed on the selected range.
3. Push until "EDIT" shows, then push .
Note: Calibration points can also be removed in calibration (CAL) mode.
4. Push until the calibration point to remove shows (i.e., S0 or S1),
then push .
5. Push until "dEL" shows, then push .
Note: The minimum number of data pairs is two. When only two data pairs
remain, no more data pairs can be removed.
6. Push two times to go back to measurement mode.
