When you choose to calibrate (press
yes
), the new calibration parameters are written into the PTC04.
Afterwards the software verifies if the writing of the calibration data in the PTC04 was done correctly.
Figure 18: The Calibration check has been ended successfully.
Now the calibration check is completed.
The END status of the calibration check is shown in the status bar of the calibration window.
What if the Calibration check failed
When the calibration fails, it is usually caused by a bad connection, measurement or incorrect input of measured
data. If this occurs, check the setup and redo the calibration check.
Very important:
If the calibration check is done with a manual voltmeter, you have to take extra care that the
measurements are done correctly. These measurements are used to calibrate the first sensing line of
the PTC-04. This sensing line will be used as reference meter for the calibration check.
The accuracy of the calibration also depends on the precision of the voltmeter and the number of digits
you enter for each measurement.
The connection of the calibration board and the voltmeter are very imported. A bad connection or any
additional load will corrupt the calibration parameters.
The decimal separator of the software is “.” Not “,”. If one uses a “,” as decimal separator, the
calibration of the first sensing line will not be done correctly.
