7750I Air Data Test Set

The Fluke Calibration 7750i ADTS offers high precision and stability for calibrating altimeters, airspeed indicators, and air data computers in ATE systems.

Manufacturer part number (MPN)

3895155 Brand: Fluke Category: Tools Automatic Go to Ground: Upon selecting the go to ground command, the 7750i safely controls the pressure to the current, local barometric pressure. The user can then disconnect the device under test (DUT) without exposing sensitive instruments to a potential pressure transient or shock. Leak Test Mode: A separate mode is provided for performing leak checks prior to beginning an actual calibration. Protecting the Device Under Test: In order to protect the DUT, the operator can program high and low limit settings for:AltitudeAirspeedRate of climbMachNegative QcARINC 565 envelope Avionics and Pressure Units: The Model 7750i displays the common avionics units including feet and meters for altitude, calibrated airspeed in knots, km/hr, and Mach with corresponding rate displays for each unit per minute. It can also display pressure units.
