Continuing with two-
point calibration
8 Set the nominal buffer value for the measured temperature with
<><>.
9 Accept the calibration value with <ENTER>.
The calibration display for the next buffer appears (voltage display).
10 If necessary, finish the calibration procedure as a single-point calibra-
tion with <M>.
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.

11 Thoroughly rinse the IDS sensor with deionized water.
12 Immerse the IDS sensor in buffer solution 2.
13 When measuring without temperature sensor:
Measure the temperature of the buffer manually and enter it with
<><>.
14 Start the measurement with <ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
15 Wait for the measurement with stability control to be completed or ter-
minate the stability control and take over the calibration value with
<ENTER>.
The pH value of the buffer solution is displayed.
