Continuing for three-
point calibration
(Cal. type TEC)
14 Thoroughly rinse the electrode with distilled water.
15 Immerse the electrode in buffer solution 3.
16 If necessary, measure the temperature of buffer 3 manually,
then enter and confirm it with <> <> and <START/EN-
TER> in the Set temperature setting.
17 Using <> <>, select Continue and press <START/EN-
TER>. The buffer is measured.
The measured value is checked for stability (AutoRead).
18 Wait for the end of the AutoRead measurement or Terminate
AutoRead with <START/ENTER> and take over the calibration
value.
The new calibration values are displayed as an informative
message (
i ).
You have the following options:
 Accept the new calibration values with <START/ENTER>.
Subsequently, the calibration record is displayed and output
to the interface at the same time.
 To switch to the measured value display without accepting
the new calibration values, press <M> (short pressure) or
<ESC>.
