Note
To ensure the high measuring accuracy of the measuring system, cal-
ibrate after the calibration interval has expired.
Setting the calibration
interval
The calibration interval is set to 7 days (d7) in the factory.
You can change the interval (1 ... 999 days):
4.6.6 Carrying out an automatic calibration (AutoCal)
Make sure that in the sensor menu, Buffer menu, the buffer set is cor-
rectly selected (see section 4.6.3).
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.
