><>.
14
Start the measurement with <MENU/ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parame-
ter flashes.
15
Wait for the measurement with stability control to be completed
or terminate the stability control and take over the calibration
value with <MENU/ENTER>.
The pH value of the buffer solution is displayed.
16
Set the nominal buffer value for the measured temperature with
<
><>.
17
Accept the calibration value with <MENU/ENTER>.
The calibration display for the next buffer appears (voltage dis-
