Function switch positions and respective GO/NO-GO
TABLE III.
frequency tolerances and nominal currents
3.6.1.2.5 Proportional functions, FUNCTION switch positions 6 and 7, PUSH
TEST switch position A.
he test set shall decode two proportional deviation
multiplex channels and provide a GO, NO-GO indication of deviation and
The frequencies associated with the proportional channels and the
polarity.
frequencies and current magnitudes required to give a GO indication are shown
in table IV. The test set shall give a GO indication throughout the tolerance
range in the FREQUENCY column.
3.6.1.2.6 Internal power supply self-test, FUNCTION switch positions 8
through 11, PUSH TEST switch position A.
he test set shall provide a GO,
NO-GO indication of the internal (test set) power supply voltages in
accordance with the data provided in table V.
3.6.1.2.7 Channel select functions, FUNCTION switch positions 1 through
4, PUSH TEST switch position B.
he two channel select inputs (pins J1-25 and
J1-26) are either +28 VDC or o VDC . The test set shall decode any combination
of these inputs and give indications as shown in table VI.
3.6.1.2.8 Pod status indication
(PSI) function, FUNCTION switch position
5, PUSH TEST switch position B. The
PSI input (J1-11) is either +28 VDC or O
VDC. The test set shall indicate in
the
area for +28 VDC at J1-11 and
indicate in the
area for O VDC at
J1-11.
3.6.1.2.9 Audio function, FUNCTION switch position 6, PUSH TEST switch
position B. The test set shall detect the presence of a 2V p-p audio input
and give a meter indication to the right.
