5.2.5 Calibration points
Calibration can be performed using one to five buffer solutions in any order
(single-point to five-point calibration). The meter determines the following
values and calculates the calibration line as follows:
22. Set the nominal buffer value for the measured temperature with
<
><
>
.
23. Accept the calibration value with
<MENU/ENTER>
.
The calibration display for the next buffer appears (voltage display).
24. If necessary, use
<M>
to finish the calibration.
The calibration record is displayed.
or
Continue calibrating using the next buffer with
<MENU/ENTER>
.
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.
