Model 3688-A Portable Air Data Calibrator Features
• Enhanced accuracy RVSM compliant test set regulates pressure/vacuum from 0 to 32 in-Hg for Ps and 0.5 to 110 in-Hg for Pt.

• Accurate: ±0.002 in-Hg for Ps and ±0.002 in-Hg for Pt from 0.5 to 42 in-Hg (±0.004 in-Hg for Pt from 42 to 110 in-Hg).

• Altitude readings displayed using feet or meters units.

• Airspeed readings displayed using Knots, km-hr, or Mach units.

• Pressure/vacuum readings displayed using in-Hg, psi, mm-Hg (Torr), in-H2O, or millibar units.

• Air data control, air data monitor, Ps control, Pt control, gauge test, leak test, and TTU-205 test modes available.

• Interactive touch panel display prompts the user through the test process and setup procedures: Reduces the likelihood of operator error.

• IEEE-488/GPIB interface enables remote control of the unit from a PC compatible computer.
