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.
9
Press the
<RUN/ENTER>
key.
The
AR
display indicator flashes.
The electrode voltage (mV) or the buffer nominal value ap-
pears on the display. Example:
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.
