Check Calibration Setup
Before the measurements for the calibration check are started, the software will perform a hardware check on the on
the calibration setup. This test will verify: if the PTC04 is well connected and in good health, if the PTC04-DB-
Calibration is plugged in on the main board, the resistors on the PTC04-DB-Calibration, if the PTC04-DB-Calibration is
connected to the reference voltmeter and if the reference voltmeter is connected to the PC (this is not the case for
the manual calibration). If the check fails the calibration check will be discontinued. The following message is
displayed if a failure is detected on the calibration setup.
Figure 19: Check calibration setup failed.
Measurement failed
The following error message is shown during the calibration procedure;
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.
Figure 20: Check Measuring line 1 Failed
Figure 21: The calibration check has been cancelled.
To determine this:
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. Please contact your local sales representative in this case.
