ISE Cal This is the conventional two-point to nine-point calibration proce-
dure that uses 2 to 9 freely selectable standard solutions. The concen-
tration expected in the measurement determines the concentration of
the calibration standards.
Stability control During calibration, the stability control is automatically activated.
The current measurement with stability control can be terminated at
any time (accepting the current value).
Calibration record The new calibration values are displayed when a calibration procedure
is finished. Then you can decide whether you want to take over these
values of the new calibration or whether you want to continue measur-
ing with the old calibration data. After accepting the new calibration val-
ues the calibration record is displayed.
Display of calibration
data and download to
interface
You can display the data of the last calibration (see page 168). Subse-
quently, you can transmit the displayed calibration data to the interface,
e. g. to a printer or PC, with the
<PRINT> key.
Sample record:
Note
The calibration record is automatically transmitted to the interface
after calibrating.
