.
A. Connect the extensometer to your controller.
B. Monitor the excitation voltage.
C. Monitor the extensometer signal.
D. Mount the extensometer onto the calibrator. Install it for the
zero position. Use the zero pin if it is available.
This figure shows a typical installation. Each extensometer
can use a variety of extensions, attachments, and other
mounting accessories.
E.
Prepare to use the calibration controls on your controller.
F.
Adjust the excitation control to set the excitation to +6 V DC
or the voltage specified in the extensometer documentation.
2. Zero the conditioner output.
The arms of the extensometer must be in the zero reference
position. Depending on the extensometer, this can be accomplished
using the zero pin, stop block, or a special fixture.
Adjust the zero control to set the extensometer signal to 0.00 V
DC.
Note
Several extensometers have asymmetrical outputs. This means
that the compression and tension outputs are not equal. Ensure
that you are aware of the maximum ratings of the extensometer
you are calibrating.
