5. Enter the full scale value of the transducer.
6. For strain transducers, enter the gauge length of the extensometer.
The system must know the gauge length of the installed extensometer in order to
calculate strain values for display and for further calculations.
7. 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, enter 100 kN as
the full scale value and 50 kN as the calibration point.
The range for a valid calibration point value is between:
8. Select Calibrate.
9. Follow the instructions provided in the Transducer Settings dialog and select OK to
proceed with the calibration:
a Set the transducer to its zero point or gauge length point.
b Deflect the transducer to its calibration point using a weight (load cell) or a cali-
bration jig (extensometer).
For force, if you have a load cell with an associated electrical calibration circuit,
you can use this to apply an electrical signal instead of applying a physical force
to the load cell.
c Return the transducer to its zero point or gauge length point.
Calibrating... displays in the transducer live display area during calibration.
10. 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.
11. Close the Transducer Settings dialog.
12. 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.

If you change the units for a field, the software converts the corresponding value to its
equivalent value in the new units. Verify that the value is correct for the specified units.
