4.4.7 Carrying out automatic calibration (AutoCal)
Make sure that in the sensor menu, Buffer menu, the buffer set is cor-
rectly selected (see page 30).
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.
3 Confirm the setting with <ENTER>.
4 Quit the menu with <M>.
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 electrode with deionized water.
4 Immerse the electrode in buffer solution 1.
5 When measuring without temperature sensor:
Measure the temperature of the buffer manually and enter it
with <
><>.
