required to perform the acceptance tests set forth in this specification.
4.3.1 A continuity checker, NOD NMD/Y or equivalent.
4.3.2 A high potential test set capable of producing ac voltage of
60 cps, continuously variable from O to 3000 volts, and containing a
sensing element to indicate insulation failure and a meter to indicate
terminal voltage.
4.3.3 A megohmmeter capable of mess-.uzing insulation resistance at
500 volts dc and including the range of 0-50 megohms with an accuracy
of 2 percent.
4.3.4 An ohmmeter, AN/USM-21 or equivaelent.
4.4 Acceptance inspections
4.4.1 Each rear cover delivered under contract shall be subjected to
the following tests and examinations. Failure to satisfactorily pass
