Extensometer Calibration: Detailed Procedure
Task 1 Get things ready
1. Review “Pre-Calibration Considerations” on page 123.
2. Locate all relevant documentation including information about the
extensometer such as the serial number, model number, etc.
3. For Automated Controllers, open a station configuration file.
You need a station configuration file that has a defined input signal, such as
an auxiliary input.
On the File menu, click Open Station to open the appropriate configuration
file.
4. Select Calibration for Access Level.
Select Config > Access Level > Calibration
5. Set up to monitor strain feedback.
You will be monitoring strain feedback when making adjustments
throughout this procedure. You should monitor strain feedback in the same
units that you are using for the calibration.
Alternatively, you can use an external DVM to monitor strain feedback from
a BNC connector located on the FlexTest SE Controller front panel
(FlexTest SE Controllers) or Analog Out panel (all other controllers).
You can also use the Meters window to monitor strain feedback.
For Automated Controllers, you can also use the Station Signals panel to
monitor strain feedback. On the Station Manager Display menu, select
Station Setup. In the navigation pane, select Station Signals to display the
Station Signals panel to monitor current values for user-defined signals.
For more information on using the Station Signals panel, refer to “About
the Station Signals Panel” in the MTS Series 793 Control Software manual.
6. Mount the extensometer to the calibrator.
A. Review the extensometer product manual for mounting information
and calibrator requirements.
B. Ensure that the extensometer is cabled to an appropriate conditioner.
