Continuing with two-
point calibration
4. Thoroughly rinse the sensor with deionized water.
5. Immerse the sensor in the first buffer solution.
6. Start the measurement with
<OK>
.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
7. Wait for the end of the measurement with stability control or accept the
calibration value with
<OK>
.
The calibration display for the next buffer appears (voltage display).
8. If necessary, finish the calibration procedure as a single-point calibra-
tion with
<MODE>
.
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 IDP
pH sensor.
