4.3.1 AutoCal TEC
For this procedure, use any two or three WTW technical buffer solutions in
ascending or descending order
(pH values at 25 °C: 2.00 / 4.01 / 7.00 / 10.01).
Note
The calibration for pH 10.01 is optimized for the WTW technical buffer solu-
tion TEP 10 Trace or TPL 10 Trace. Other buffer solutions can lead to an er-
roneous calibration. The correct buffer solutions are given in the WTW
catalog or in the Internet.
Note
The buffer solutions are automatically recognized by the measuring instru-
ment. Depending on the instrument setting (see section 4.6 C
ONFIGURATION
),
the instrument displays the relevant buffer nominal value or the current elec-
trode voltage in mV.
Note
Skip the steps 2, 7 and 14 if you use a temperature sensor.
1 Press the <CAL> key repeatedly until the Ct1 display indicator and
the function display AutoCal TEC appears. The sensor symbol dis-
plays the evaluation of the last calibration (or no sensor symbol in the
delivery state or after the measurement parameter has been reset).
2 If necessary, enter the temperature of the first buffer solution with

3 Immerse the pH electrode in the first buffer solution.
4 Press the <RUN/ENTER> key.
The AR display indicator flashes.
The electrode voltage (mV) or the buffer nominal value appears on
the display. Example:
