Continuing with
three- to seven-point
calibration
Repeat the steps 12 to 17 in the same way with the third and further standard
solutions as necessary. The new calibration values are displayed after the last
calibration step was completed.
15. When calibrating without temperature sensor:
Measure the temperature of the standard solution using a thermom-
eter.
Use <F4>/[ ⇅ ] to select the setting of the temperature.
Use <><> to set the temperature.
Use <F4>/[ ⇅ ] to select the setting of the concentration.
16. Set the concentration of the standard solution with <><> and
press <ENTER>.
The standard solution is measured.
The measured value is checked for stability (AutoRead).
17. Wait for the end of the AutoRead measurement or accept the calibra-
tion value with <ENTER>.
The calibration display for the next standard solution appears.
18. Press <ENTER> to continue with three-point calibration.
or
Finish the calibration procedure as a two-point calibration with <M>.
The new calibration values are displayed.
Based on the calibration data, the calibration curve is determined
in sections, according to the Nernst equation modified by Nikolski.
