this stage keep the sensor in the relevant measuring water or buffer
solution (see chapter “5 Measuring values inputs” on page 18).
Enter the requested reference value for the water / solution: The first
digit of the set value is highlighted in grey and can be adjusted.
Use the arrow keys to set up the value:

Confirm the measuring water extraction with the “OK” key.
When calibrating free chlorine and the pH-value the sensor s pulse rate
is shown at the connection to the calibration.
Special feature for the calibration of the pH value
The actual voltage of the single-rod measuring cell AND the design volt-
age of the pH buffer solution are indicated on the display during calibra-
tion of the pH value. These two values allow the operator to monitor the
accuracy of the measuring electrode.
The deviation between the measurement of the pH value with the pho-
tometer and the electrometric measurement can be compensated with
the "offset compensation" option.

The actual trend of the measurements is represented by coloured
curves. These can be constructed at different time intervals. A time
range of 60 minutes, 4 hours or 24 hours can be displayed. To change
the desired time to a respectively bigger or smaller interval use the
„Zoom +“ and „Zoom -“.
