The following table shows the proper conditioner output for each clip-
on gage displacement of the preceding example.

How to Use a Calibration Block
MTS recommends using a calibration block to establish the initial gain
setting of the conditioner. The calibration block is a metal block with
knife edges mounted to it or machined in it. Using multiple knife edges
allows you to adjust the gain for a variety of specific displacements.
Use this procedure as a guideline to calibrate other clip-on gages.
1. Set up the controller.
Your test controller must be configured to use the clip-on gage
signal.
A. Connect the clip-on gage to your controller.
B. Monitor the excitation voltage.
C. Monitor the clip-on gage signal.
D. Prepare to use the calibration controls on your controller.
E. Adjust the excitation control to set the excitation to +6 V DC
or the voltage specified in the clip-on gage documentation.
2. Zero the conditioner output.
