Calibrating an Extensometer

Task 5 Gain/Linearization Calibration
If you are using Gain/Linearization for your calibration type,
complete the following procedure. If not, complete Task 4 Gain/Delta
K Calibration on page 178.
Important Using linearization data requires specific conditioner zeroing
practices. Ensure that Electrical Zero Lock on the Offset/
Zero menu is set to Locked. Adjusting electrical zero after
calibration may invalidate linearization data.
Initial extensometer
calibration
For initial calibration of an extensometer, complete the following
procedure:
1. Select Gain/Linearization for Cal Type.
Stand-Alone— Path: Setup > Strain > Calibration > Cal Type >
Gain/Linearization
Automated— Select Gain/Linearization for Cal Type on the
Calibration tab of the Inputs panel.
2. Exercise the extensometer.
Stand-Alone— Enable the front panel Dial, use Setpoint 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. Path: Status > Setpoint
Automated— Use the Manual Cmd slider on the Manual
Command window 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.
3. Apply a negative strain command that is 80% of the negative full
scale range.
Stand-Alone: Using the Dial, adjust the Setpoint for a negative
strain command that is 80% of the full scale range.
Automated: Adjust the Manual Cmd slider for a negative strain
command that is 80% of the full scale range.
Verify that your extensometer feedback signal is 80% of the full
scale range.
