19. Immediately empty and rinse the sample cell. Rinse the sample cell
and cap three times with deionized water (or distilled water).
Note: As an alternative, tap water can be used to rinse the sample cell if the
concentration of the parameter in the tap water is less than the samples
measured.
20. Push and hold for 3 seconds to go back to measurement mode.
8.2.2 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.
1. Push to set the instrument to the range to calibrate (e.g., LR or
HR).
2. Push and hold for 3 seconds to enter menu mode.
3. Push until "USEr" shows, then push .
4. Push until "Edit" shows, then push .
5. When "S0" shows on the display, push .
6. Enter the first data pair.
The first data pair is S0 (concentration value) and A0 (absorbance
value).
• Push or to change the number that flashes.
• Push to go to the next digit.
• Push to go to the previous digit.
7. Do steps 5 and 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 and 6 again to enter more data pairs.
9. Push and hold for 3 seconds to go back to measurement mode.
