4.5.2.2.1 Pressure tester. Special test equipment (STE) in
accordance with Drawing F8565556, or equivalent, shall be provided
to check the sealing of the unit.
4.6 Test methods and procedures
4.6.1 Test conditions. Unless otherwise specified, the test
conditions shall be in accordance with the test facilities provisions
of MIL-F-13926.
4.6.1.1 Initial conditions. Unless otherwise specified,
connect the loads and power to the unit as specified in table I.
4.6.2 Safety interlock test. With no power applied, measure
the resistance between J3-D and J4-X to determine compliance with
3.3.1.1. Remove the unit top cover and again measure the resistance
between J3-D and J4-X to determine compliance with 3.3.1.1. Install
the unit top cover, then remove the PFN and again measure the resis-
tance between J3-D and J4-X to determine compliance with 3.3.1.1.
4.6.3 Primary power test. Apply the logical zero type-A
signal of table I to J1-q, then apply the primary power as listed in
table I. Measure the outputs at the pins listed in table II to determine
compliance with 3.3.1.2.
4.6.4 Rnage readout test. Remove the Circuit Card Assembly:
10559305 (Counters) from the unit and substitute the range data output
generation circuit (item 4.2 of table I). Separately close each switch
on the range data output generation circuit (figure 3) and observe the
range readout on the Circuit Card Assembly: 11737350 (Readout) to
determine compliance with 3.3.1.3.
