Calibration
evaluation
After calibration, the system automatically evaluates the current status of the
calibration. The evaluation appears also in the calibration record.
Note
The calibration history with the data of the last 20 calibration procedures can
be displayed at any time (see section 6.4 V

Note
The logger can store up to 20 logging jobs with the respective calibration
records and setting data. If, however, you calibrated several times for one
logging job and the logger would thus have to store more than 20 calibration
records with the 20th logging job, a message informs you of this.
This is to ensure that no calibration record for which there are measured
values can be lost. In this case the logger will prompt you to delete the
logger memory.
Make sure that you have read in all data you want to use before deleting the
logger memory. The logger memory can only be deleted completely.
