Continuing with
three- to five-point
calibration
18. If necessary, finish the calibration procedure as a two-point calibration
with
<MODE>
.
The calibration record is displayed.
19. Thoroughly rinse the sensor with deionized water.
20. Immerse the sensor in the next buffer solution.
21. When measuring without temperature sensor:
Enter the temperature of the buffer with
<

><

>
.
22. Start the measurement with
<OK>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
23. Wait for the measurement with stability control to be completed or ter-
minate the stability control and take over the calibration value with
<OK>
.
The pH value of the buffer solution is displayed.
24. Set the nominal buffer value for the measured temperature with
<

><

>
.
25. Accept the calibration value with
<OK>
.
The calibration display for the next buffer appears (voltage display).
26. If necessary, use
<MODE>
to finish the calibration.
The calibration record is displayed.
or
Continue calibrating using the next buffer with
<OK>
.
After the fifth buffer has been measured the calibration is automat-
ically finished. Then the calibration record is displayed.
The calibration line is determined by linear regression.
