8 Thoroughly rinse the electrode with distilled water.
9 Immerse the electrode in buffer solution 2.
10 If the Set temperature menu item appears, measure and enter
the temperature of the buffer manually (measurement without
temperature sensor).
11 Using <> <>, select Continue and press TER>. The buffer is measured.
The measured value is checked for stability (AutoRead).
12 Wait for the end of the AutoRead measurement or Terminate
AutoRead with and take over the calibration
value.
The calibration display for the next buffer appears.
13 For two-point calibration, select Exit with 2 point calibration with
<> <> and confirm with .
The calibration is completed as a two-point calibration.
The new calibration values are displayed as an informative
message (
i ).
You have the following options:
 Accept the new calibration values with .
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 (short pressure) or
.
