Continuing for two-point

calibration

(Cal. type TEC)

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 <START/EN-

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 <START/ENTER> 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 <START/ENTER>.

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 <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>.
