Patent ID: 8692569

Claim:
A circuit tester for testing for testing circuit boards comprising: a housing having first and second parts hinged together; a first board mounting plate affixed to the first part of said housing; a probe plate attached to the second part of said housing, said plate having at least one probe at least one of said plates being slideably attached to said housing to permit lateral shifting thereof within a predetermined range of lateral movement by at least one shoulder bolt received within at least one hole in one of the plates, said hole having a diameter larger than said shoulder bolt to loosely secure the plate while allowing lateral shifting thereof in an amount generally equal to a differential between a shoulder bolt diameter and the hole diameter, thereby defining a predetermined range of lateral movement; at least one aligner between said board mounting plate and said probe plate for bringing said probe plate into desired alignment with said board when said first and second parts are hingedly brought together, so that the plates may move relative to each other.
