Note
For
single-point calibration
, the instrument uses the Nernst slope
(-59.2 mV/pH at 25 °C) and determines the zero point of the electrode.

.
9
Accept the calibration value with
<ENTER>
.
The calibration display for the next buffer appears (voltage dis-
play).

If necessary, finish the calibration procedure as a single-point
calibration with

.
The calibration record is displayed.

Buffer
11
Thoroughly rinse the electrode with deionized water.
12
Immerse the electrode 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 parame-
ter flashes.
15
Wait for the measurement with stability control to be completed
or terminate the stability control and take over the calibration
value with
<ENTER>
.
The calibration display for the next buffer appears.
