pH 330i/340i Operation

Note
At this point, the AutoCal TEC calibration can be terminated with <M>.
This corresponds to a two-point calibration.
The instrument uses the slope and asymmetry of the calibration
range I.
10 When the measured value is stable, AR disappears. The in-
strument displays the value of the slope (mV/pH) and the eval-
uation of the calibration in calibration range I.
11 Press the <RUN/ENTER> key. The instrument displays the
value of the asymmetry in calibration range I.
