SECTION 1 : INTRODUCTION
The model 6300 is a high accuracy automated pressure controller, specifically designed for controlling air
data parameters such as altitude, airspeed, Mach and climb. This instrument can also be used to control
pressures in units of inHg, mbar, psi, mmHg and kpa. The 6300 is equipped with internal pressure and
vacuum pumps. The Remote unit is used to interface with the Main unit. The small size of the Remote unit
allows it to be used in the cockpit of an aircraft.
The 6300 has two high accuracy transducers that measure pressure in the range of 1 to 32 inHg absolute on
the Static output, and 0 to 30 inHg differential on the Pitot output. These transducers are designed to
accurately measure the pressure of dry air over an ambient temperature range of -40
o
C to 80
o
C. The high
accuracy of the Pitot transducer makes it ideal for checking the low airspeeds typical in helicopters. The high
accuracy of the Static transducer makes the 6300 fully RVSM compliant.
The 6300 allows the user to control altitude in feet or meters, climb in feet per minute or meters per second.
Airspeed can be controlled in knots, mach, km/hr and mph. Airspeed-rate can be also be controlled in these
units. The 6300 also allows the user to control EPR on the pitot output.
The model 6300 features programmable limits on altitude, airspeed, airspeed rate, mach number, and climb
rate. These limits are checked during data entry and thereby prohibit entry of erroneous target values. These
limits are also checked continuously during operation, and if any of these is exceeded, the unit automatically
takes abortive action.
The user has the ability to program into the 6300 a profile of set-points to be controlled in a sequence. Once
such a profile has been setup, the user can command the unit to move from one set-point to the next simply
by using the Up-arrow key. Up to 50 points can be stored in one profile. The 6300 can store up to 15 such
profiles in non-volatile memory at any one time.
Calibration of the unit is required only once a year. This process is the only scheduled maintenance function
required on the 6300.
The standard version of the model 6300 operates on AC power and comes with an RS232 interface. Options
include an internal battery which lasts up to 8 hours, internal heaters which allow the unit to operate down to
-40
o
C, and an altimeter-encoder interface.
The 6300 has built-in Wi-Fi capability which allows for wireless remote operation using an iPad.
