0.0164VDC/m).ARINC429 FPDP reading (seeing table 1) changes the most therewith.
(5) high accuracy inspection is surveyed
500ft delay line, regulation variable attenuator is selected to make transceiver just be in blocking and (i.e. simulate output
Between 1H and 1L, port voltage is more than 18V), reduce loop attenuation amount 8～10dB, measure " simulation output " (1H
And between 1L) port voltage, should be between 2.449～2.549VDC, ARINC429OUT port reading
(seeing table 1) should be between 149.35～155.45m.
(6) self-inspection inspection
Triggering and once " test " button, " test " lamp is glittering once, measures " simulation output " (between 6 and 7)
Port voltage, should be in the range of 0.492 ± 0.033VDC；Measure ARINC429OUT port reading (ginseng
It is shown in Table 1) should be in the range of 30 ± 2.0m.
(7) zero elevation calibration
Under the normal operating conditions of 0m height, zero elevation more than the calibration knob 10s in pressing component,
Measuring ARINC429OUT data readings should be in the range of 0 ± 0.6m.
