Note
At this point, the AutoCal TEC calibration can be terminated with
<M>. This corresponds to a two-point calibration.
TP
l Immerse the pH electrode in the second buffer solution to continue the
two-point calibration.
l When measuring without a temperature sensor:
Enter the temperature of the third buffer solution with < > < >.
l Press <RUN/ENTER>. The AutoRead measurement begins. The elec-
trode voltage (mV) or the buffer nominal value appears on the display.
l If the measured value is stable, the instrument displays the value of the
slope and the evaluation of the three-point calibration.
l Press <RUN/ENTER>. The instrument displays the value of the asymme-
try.
l Switch to the measuring mode with <M>.
