Continuing with two-
point calibration
7. Wait for the measurement with stability control to be completed or ter-
minate the stability control and take over the calibration value with
8. Set the nominal buffer value for the measured temperature with
<><>.
9. Accept the calibration value with
10. If necessary, finish the calibration procedure as a single-point calibra-
tion with .
The calibration record 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 IDS
pH sensor.
