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:
Measurement failed
The following error message is shown during the calibration procedure;
Figure 18: Check Measuring line 1 Failed
To determine this:

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.
If there is a bad connection in the setup. For example: between the PTC04 main board and the
calibration board.
When using a Keithley 2000 multimeter for the calibration, the failure can also be caused by a
wrong measurement of the Keithley. For example: communication error.
When you are using the manual calibration procedure. The software will perform a check on the
data you enter. If there is a large deviation from the expected data. The check will fail and the
calibration check is ended.
Press OK on both messages to cancel the calibration check.
Remove the calibration board, place it back and check the connections with the voltmeter. The
connection of the calibration board and the voltmeter are very imported. A bad connection or any
additional load will corrupt the calibration parameters.
After checking the setup, restart the calibration check. If the same channel fails again it is possible
that there is hardware damaged on the PTC04.
