Back Plane Tester
|
|
| This machine is used to
test back planes used in telecommunications central stations. An operator
loads a completed point to point wired back plane onto a retractable
shelf on the front of the tester. The shelf is pushed back into the
machine where it is held in place by pneumatic operated clamps. Then
a series of pneumatic cylinders sequentially insert a test card into
each location in the back plane. A remote instrument performs a complete
point to point continuity, short and hi pot test on all connections
in the back plane.
