9.3. Calibration solution
Displays types of calibration solutions applied for the last calibration:
- calibration with manually entered buffers‘ values;
- calibration with automatic correction of the standards‘ values.
Calibration in buffers and standards is described in detail in the chapter 10.
The types of calibration solutions are stored for each of the three
electrodes separately and may be changed only in the calibration mode
(point 10.2).
9.4. Calibration points and date
After pressing the
button the following parameters are displayed
(Pic. 4C): the electrode condition, calibration points, validity time and date of
the last calibration. Markers next to the calibration points windows inform that
the last calibration was performed in these particular solutions. All the
parameters‘ values are stored separately for each of the three electrodes.
The calibration points may be changed only after entering the
calibration mode (point 10.2).
9.5. Calibration validity date
The meter stores the calibration validity time for each of the three electrodes
separately. Expiry of this date is signalised with yellow electrode number. To
set the calibration validity expiry date, press the
VALIDITY
window, the
numerical keyboard will appear to enter the number of days and confirm with
the
button.
