4.6 Tests.
4.6.1 Examination. The transmitter shall be examined to determine compliance with
materials, identification, weight, and those interface and performance requirements
indicated in table III.
4.6.2 Scale error. The transmitter shall be tested for scale error at the test points specified
in the acquisition document for both upscale and downscale readings. The test points on the
upscale reading shall be measured by bringing the input reading up to, but not exceeding,
the specified test point. The transmitter shall then be vibrated at a frequency of 3,600Hz
with an amplitude of 0.002 inch. The difference in the scale error after vibration from the
true input value shall not exceed the scale error tolerance specified in the acquisition
document. The downscale error shall be measured in the same manner, except that the
input reading value shall be brought down to, but not below, the specified test point.
4.6.3 Friction error. The difference in readings prior to application of the vibration
specified in
4.6.2 and after application of vibration is friction error. The friction error shall not exceed
the friction error tolerance specified in the acquisition document.
4.6.4 Aircraft attitude. The transmitter shall be energized to obtain a reading of one half
scale on the indicating standard. The change in indication produced by rotating the
transmitter from the normal operating position to a position 90° clockwise and
counterclockwise (longitudinal axis vertical) shall not exceed the tolerance specified for
position error in the acquisition document. The position error test may be conducted in
conjunction with the scale error test.
4.6.5 Dielectric strength. An electric potential shall be applied between each pin of the
electrical connector and the case for 5 seconds. There shall be no breakdown of the
insulation. The potential shall be 500Vac if the case is not hermetically sealed, and 250Vac
if the case is hermetically sealed.
4.6.6 Sealing (applicable to hermetically sealed transmitters only). The case shall be tested
for leaks with a mass spectrometer helium detector. Where a nitrogen-helium mixture is
