8. The calibration was successful if a value displays in the transducer live display area
and the transducer icon in System Details is no longer grayed.
9. Close the Transducer Settings dialog.
10. Close System Details.
The calibration is saved with the transducer configuration and is restored whenever the
transducer configuration is selected.
The transducer is now calibrated and ready for testing. The transducer must be
associated with a measurement in a method. Verify that the method used for testing
includes a measurement that is linked to the transducer configuration for this
transducer.
Manual calibration
During a manual calibration, you apply a measured physical force to the transducer and
the system calibrates on the signal that is output as a result of that force. For force
calibration, you can hang a measured weight from the load cell. For strain calibration,
you can install the extensometer on a specially designed calibration jig to apply a
precise deflection to the extensometer.
The system only saves the values entered for a manual calibration after there is a
successful calibration. If you select a different transducer configuration or close the
dialog before calibrating a transducer configuration, the calibration fields revert to the
default values for that configuration.
Manual calibration of a rationalized force or strain transducer
1. Select in the console area to open System Details.
2. In the System Settings area, select the icon for the transducer to open the Transducer
Settings dialog.
3. Under Settings, select the transducer configuration in the Transducer configuration
field.
4. Set Calibration type to Manual.
5. Enter a value for the calibration point. This value is the force (for a load cell) or deflec-
tion (for an extensometer) that you apply to the transducer during calibration.
For example, to calibrate a 100 kN load cell using a 50 kN weight, the full scale value
is 100 kN and the calibration point is 50 kN.
The range for a valid calibration point value is between:
