4.3.11 Electrical.
4.3.11.1 Continuity. - The STG shall be inspected by standard
measuring equipment (SME) and visual examination for compliance with 3.5.1.
4.3.12 Performance. - Unless otherwise specified, the performance tests
as cited herein shall be satisfactorily met at standard ambient conditions
standard ambient conditions for the purpose of these tests shall be defined
as:
a. Temperature between 60F and 90F.
b. Barometric pressure between 28 and
32 inches of mecury.
c. Relative humidity (RH) up to 90%.
4.3.12.1 Test Set-up. - The input voltage shall be 28.0 0.1 VDC
and the initial test switch positions shall be as follows:
POSITIONS
SWITCH

4.3.12.1.1 Testing. - Subsequent to each power on/test cycle the
reset switch shall be depressed and the boresight indicator depressed
and released such that the indicator light is extinguished.
4.3.12.1.2 Digital output. - The "O" or false output level shall
be between 0.00 and 0.40 VDC. The "1" or true output level shall be
between +2.40 and 5.45.
4.3.12.1.3 Power requirements. - In order to determine compliance
with paragraph 3.6.1, there shall be continuity between pins J3= and J4A
and between J3m and J4A when no power is applied. When power is applied and
the on/off switch in the "off" position the red indicator shall glow. With With
