MTS Clip-On Gages - Manual (Page 30)

Installation 30
• Knife edges must be added to the specimen.
– Depending on the model of the clip-on gage and the specimen
standard, knife edges are either machined into the specimen or
attached to the specimen.
– If the knife edges are attached to the specimen, use the
alignment fixture to establish the edge length and knife edge
alignment.
How to Connect the Cable
The clip-on gage cable connects to a controller via an extension cable.
The clip-on gage assembly includes a small cable and connector. An
extension cable is installed between the clip-on gage connector and the
system controller. Ensure that the clip-on gage is connected to the
appropriate controller connector. The controller connector must be
associated with a DC conditioning circuit. The following figure shows
the circuitry and connector pin assignments from the clip-on gage.
