10. Thoroughly rinse the pH electrode with deionized water.
11. Immerse the pH electrode in the second buffer solution.
12. When measuring without temperature sensor: Enter the temperature of
the buffer with

.
13. Start the measurement with
<ENTER>
.
The measured value is checked for stability (stability control).
The
[AR]
status display flashes.
The electrode voltage (mV) or the nominal value of the buffer is displayed
(setting: see section 7.1.1 C
14. Wait for the measurement with stability control to be completed or termi-
nate the stability control and take over the calibration value with
<ENTER>
.
The calibration display for the next buffer appears.
Ct3
or
Cd3
is displayed.
For single-point calibration, the instrument uses the Nernst
slope (-59.2 mV/pH at 25 °C) and determines the zero point
of the pH electrode.
