4.5.4 Operating life span. After satisfactory completion of the reliability test, and if specified
in the acquisition document (see 6.2) an operating life span of 3,000 hours shall be
demonstrated by continuing the reliability test. The transmitter shall be repaired when failures
occur and testing continued until the transmitter has operated 3,000 hours.
4.5.5 Compatibility. The transmitter shall be connected to and tested with indicators specified
in MIL-I-25437, MIL-I-25438, MIL-I-27189, and MIL-I-38133. The transmitter and indicators
shall be connected as shown in figure 1. The scale error test in MIL-PRF-25435 shall be
performed at ambient temperature. The tolerance at each test point shall be the sum of the
tolerances in table I of this document and table I of MIL-I-25438 at ambient temperature.
