Continuing with two-
point calibration
9. Set the nominal buffer value for the measured temperature with
<S
SS
S><T
TT
T>.
10. Accept the calibration value with <ENTER>.
The calibration display for the next buffer appears (voltage display).
11. 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.

12. Thoroughly rinse the sensor with deionized water.
13. Immerse the pH sensor in buffer solution 2.
14. When measuring without temperature sensor:
Measure the temperature of the buffer manually and enter it with
<S
SS
S><T
TT
T>.
15. Start the measurement with <ENTER>.
The measured value is checked for stability (stability control).
The [AR] status indicator is displayed. The measured parameter
flashes.
16. 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.
