MTS Clip-On Gages - Manual (Page 29)

Installation 29
Installation
This section describes how to install a clip-on gage onto a prepared
specimen.
Handling the clip-on gage while it is selected as the active control
mode can cause the actuator to move unpredictably.
Unpredictable actuator movement can cause personnel injury or
damage to the test equipment.
Ensure that the clip-on gage is not active when handling it.
The shield of the Extensometer (pin E for PT style connector and pin A
for Amphenol style connector) must be connected to the controllers
chassis ground. This is typically accomplished by using a metal or
metalized plastic connector and a braided shielded cable from the
controller to the Extensometer cable, see MTS cable part numbers 50-
120-0xx PT style or 56-233-6xx Amphenol style for an example.
Post installation
After you have installed the clip-on gage you need to perform the
following:
• Connect the cable to your controller.
• Calibrate the clip-on gage.
How to Prepare a Specimen
The specimen must be prepared to accept the clip-on gage. The
following must be done to prepare the specimen for use with a clip-on
gage:
• The specimen size and shape must conform to standards.
• Holes must be drilled to accommodate the grips.
• A crack starter notch must be created according to standards.
