pH 315i Operation

4.3.1 AutoCal TEC
For this procedure, use any two or three WTW technical buffer solu-
tions 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
solution TEP 10 Trace or TPL 10 Trace. Other buffer solutions can lead
to an erroneous 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 in-
strument. Depending on the instrument setting (see section
4.4 C
ONFIGURATION
), the instrument displays the relevant buffer nomi-
nal value or the current electrode voltage in mV.
1 Press the <CAL> key repeatedly until the Ct1 display indicator
and the function display AutoCal TEC appears. The sensor
symbol displays the evaluation of the last calibration (or no
sensor symbol in the delivery state or after the measurement
parameter has been reset).
2 Immerse the pH electrode in the first buffer solution.
3 Press the <RUN/ENTER> key. The AR display indicator flash-
es.
The electrode voltage (mV) or the buffer nominal value ap-
pears on the display. Example:
