Note
At this point, the AutoCal TEC calibration can be terminated with
<M>. This corresponds to a two-point calibration.
•
Immerse the pH electrode in the second buffer solution to continue the
two-point calibration.
• When measuring without a temperature sensor:
Enter the temperature of the third buffer solution with < A > < T > .
•
Press <RUN/ENTER>. The AutoRead measurement begins. The elec-
trode voltage (mV) or the buffer nominal value appears on the display.
