Note
At this point, the AutoCal TEC calibration can be terminated with
<M>
.
This corresponds to a
single-point calibration
. To do this, the instru-
ment uses the Nernst slope (-59.2 mV/pH at 25 °C) and determines the
asymmetry of the electrode.
5
When the measured value is stable,
Ct2
appears.
6
Thoroughly rinse the electrode with distilled water.
7
If required, enter the temperature of the second buffer solution
with

while keeping the
<RUN/ENTER>
key de-
pressed.
8
Immerse the pH electrode into the second buffer solution.
9
Press the
<RUN/ENTER>
key.
The
AR
display indicator flashes.
