If the extensometer has been previously calibrated, use the following
procedure:
1. Locate the calibration data sheet for the appropriate conditioner.
2. Turn off system hydraulics.
3. Click Linearization Data to open the Linearization Data window.
4. Transfer Standard and Conditioner data from the conditioner’s
calibration data sheet to corresponding data entries on the
Linearization Data window.
5. Turn on system hydraulics.
6. Verify linearization data.
A. Adjust the Setpoint (Stand-Alone) or Manual Cmd slider
(Automated) for each strain command point on the
Linearization Data window.
B. At each command point, verify both the calibrator readout
value (Standard) and its corresponding conditioner feedback
value (Conditioner) by comparing them with the
corresponding values on the Calibration Data sheet
If the data is valid
: Stop this procedure.
If the data is not valid
: Proceed to the next step.
7. Reset Linearization Data window to default values.
Stand-Alone— Path: Setup > Strain > Calibration > Cal
Type > Gain/Linearization > <<Reset>>
Automated— Click Reset on the Linearization Data window
to return to default values.
8. Use the Setpoint (Stand-Alone) or Manual Cmd slider
(Automated) to adjust the calibrator between zero and 100% of the
extensometer’s full-scale range three times. This exercises the
extensometer to remove any hysteresis.
