Using the Model 2450 in a custom test fixture or system
You can use the Model 2450 safely with a properly designed custom test fixture or with a
semiconductor device prober or handler.
Connect the enclosure of all metal test fixtures to protective earth (safety ground).
Nonconductive test fixtures must be rated to double the maximum capability of the test
equipment in the system. Failure to attach the ground wires to a known protective earth may
result in electric shock.
