4.4.3.1 Group C failures. Actions required relative to Group C failures shall be specified
in the contract (see 6.2.d).
4.4.3.2 Disposition of Group C samples. Group C samples shall be accepted on contract
subsequent to the tests of Table III.
4.5 Test methods of inspection.
4.5.1 Channel-to-channel tracking. First, measure voltage gain (4.5.3) adjusted to a gain
greater than 7,000 v/v. The postamplifier shall meet the requirements of 3.5.1 without
adjustment of channel gain controls over the specified range. Channel-to-channel tracking shall
be tested using the postamplifier with an auxiliary control module (see 6.2 i) with both modules
placed together in a temperature chamber. This test may be performed in conjunction with the
temperature tests of 4.6.1, 4.6.2 and 4.6.3.
Voltage gain of each channel is defined by the following equation:
_
(k1) · AT · [(AI,T = 25°C)/(AT=25°C)] ≤ AI,T ≤ (k2) · AT · [(AI,T=25°C/(AT=25°C)]
I=20
