| 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:
- Altitude
- Airspeed
- Rate of climb
- Mach
- Negative Qc
- ARINC 565 envelope
|
| Automatic Volume Characterization |
The 7750i automatically tunes the controller into external volumes ranging from 5 to 60 cubic inches (80 to 1000 cc). This allows a large degree of flexibility for the configuration of the test system and the type of aircraft and components to be tested. For component manufacturers, a large number of devices can be tested simultaneously on a single manifold. |
| Automatic Zeroing |
As with any instrument, regular zeroing is suggested to achieve maximum performance. This task is now automated and can be performed at the push of a button, or over the PC interfaces. The 7750i incorporates the vacuum sensor onboard; no separate or external vacuum gauges or sensors are required. In addition, only one vacuum pump is required to operate and zero the 7750i ADTS. Zeroing is performed in 30 to 45 minutes using the specificed vacuum pump. |
| 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. |
