Operation
19
During buffer recognition CAL 1 is flashing. The
right display reads the measured temperature.
When you use manual temperature compensation,
the entered temperature is displayed. This is indi-
cated by a flashing decimal point.
The nominal value of the identified buffer solution is
displayed for approx. 5 sec. Electrode and temper-
ature probe still remain in the first buffer solution.
Stability of the electrode is checked. The left-hand
display reads the measured mV value. The right-
hand display shows a running clock measuring the
electrode response time. For each revolution
(4 sec), a mark is added to the tally beside the
clock. Stability check can be stopped by pressing
. However, this reduces calibration accuracy.
Calibration with the first buffer is terminated. Take
the electrode and temperature probe out of the
solution and rinse them thoroughly.
• If you only want to perform a one-point calibra-
tion, press
to stop calibration, or select
CAL2 NO using
and press
to exit the
Calibration level. The meter will display the new,
calculated zero point and the old slope and return
to measuring mode.
• If you want to perform a two-point calibration,
immerse the electrode and temperature probe in
the second buffer solution. Press
or
to restart calibration. The calibration process
runs again as for the first buffer.
