a. 10.000 plus or minus 0.010 volts DC to pin W (-) and to
pin C (+) of connector P3 for not less than 2 seconds.
b. Set-in voltages across pins C (+) and W (-) as specified in
Table 6 for 100 plus or minus 0.1 milliseconds. Rise time of the 100 milli-
second pulse shall not be greater than 150 microseconds and fall time not
greater than 250 microseconds. Pulse width shall be measured at the -25 volt
level with a -50 volt set-in. Switching time from presaturation to set-in
voltage shall not be greater than 1 millisecond.
c. 0.200 plus or minus 0.001 volts DC across pins C (+) and W (-).

3.3.11.3.2 Readout at 2.500 Volts. Elapsed time from the instant
a 2.500 voltage is applied in (c.) below until the voltage across pins D (+)
and W (-) of P3 reaches 4.0 plus or minus 0.5 volts DC shall be 2.00 plus or
minus 0.10 seconds after the application of voltages in the sequence specified
in steps (a.) through (c.) below. The variation of plus voltage between pins
D (+) and W (-) of P3 shall not exceed 0.500 volts peak after application of
the 100 millisecond pulse in step (c.) and prior to completion of the the
period of 2.00 plus or minus 0.10 seconds.
a. 10.000 plus or minus 0.010 volts DC! to pin W (-) and to pin
C (+) of connector P3 for not less than 2 seconds.
b. A set-in voltage of -50.000 plus or minus 0.020 volts DC across
pins C (+) and W (-) for 100 plus or minus 0.1 milliseconds. Rise time, fall
time, pulse width, and switching time requirements shall be as specified in
3.3.11.3.1 (b.).
c. 2.500 plus or minus 0.010 volts DC across pins C (+) and W (-).
3.4 Environmental Requirements
3.4.1 High Temperate. The Test Set shall withstand a temperature of
plus 160 plus 5 minus 0 degrees F for not less than 8 hours, and thereafter
meet all operational requirements specified herein while the Test Set is
stabilized at plus 120 plus 5 minus 0 degrees F.
