Carrying out an automatic calibration (AutoCal)
Make sure that the correct buffer set is selected in the sensor menu,
Buffer
submenu (see page 32).
Of the selected buffer set, use one to five buffer solutions of your choice
in ascending or descending order.
Calibration with Technical buffers is described below (TEC). With other
buffer sets, other nominal buffer values are displayed. Apart from that,
the procedure is identical.
Note
If single-point calibration is set in the menu, the calibration is
automatically terminated after measurement of buffer solution 1 and
the calibration record displayed.
