17.3.3
Slope calibration (free chlorine, pH/Temp.-compensated)
Step
Action
1
Start the slope calibration.
Device menu > Calibration > Select Universal Input > Slope Cali-
bration
2
Clean the sensor and immerse it in the test solution.
3
Check the displayed values for the pH value and
temperature. Automatic sensing can be configured in the calibra-
tion default settings for both measurands independently of one an-
other. With automatic acquisition, the particular influencing
variable is only displayed and can no longer be changed here.
Without automatic acquisition, the particular influencing variable
must be entered manually here.
Wait until the measured value displayed stabilizes and then check
the pH value displayed. Then confirm by pressing "OK".
