4.7.6 Carrying out an automatic calibration (AutoCal)
Make sure that in the sensor menu, Buffer menu, the buffer set is cor-
rectly selected (see section 4.7.3).
Use any one to five buffer solutions of the selected buffer set in ascend-
ing or descending order.
Below, calibration with Technical buffers ( TEC ) is described. When
other buffer sets are used, other nominal buffer values are displayed.
Apart from that, the procedure is identical.
Note
If single-point calibration was set in the menu, the calibration procedure
is automatically finished with the measurement of buffer solution 1 and
the calibration record is displayed.
1 In the measured value display, select the measured parameter
pH or mV with
<M> .
2 Start the calibration with <CAL> .
The calibration display for the first buffer appears (voltage dis-
play).
3 Thoroughly rinse the IDS sensor with deionized water.
4 Immerse the IDS pH sensor in buffer solution 1.
5 For measurements without temperature sensor
(e.g. when using an IDS adapter
)
:
Measure the temperature of the buffer manually and enter it with
<

><

> .
6 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.
