Continuing with two-
point calibration
8.
Set the nominal buffer value for the measured temperature with
<
><
>
.
9.
Accept the calibration value with
<MENU/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 pH 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
<MENU/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
<MENU/ENTER>
.
The pH value of the buffer solution is displayed.
