43. Hydraulic Pressure Measurement System
a. Performance Check (T53/T55/T63/T64/714A Mode)
Ensure that the FEDS is in the T53/T55/T63/T64/714A test mode (Reference FEDS operator's manual).
Calibrate AEDATS concurrently with the vertical scale indicators.
(1) MT3:
0-50 PSIG (T53/T55/T63/64/714A)
Using the pressure calibrator, apply the following pressures to MT3 and record the results
