8. Wait for the measurement with stability control to be completed or termi-
nate the stability control with <ENTER>.
The calibration display for the next buffer appears.
Ct2 or Cd2 is displayed.
9. If necessary, finish the calibration procedure as a single-point calibration
with <M>.
The calibration record is displayed.
or
Continue calibration using the next buffer with <ENTER>.
Continuing with two-point calibration
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

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.
