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.

SECTION 2 : CONTROLS & CONNECTIONS
2.1 MAIN UNIT, TOP PANEL
The model 6300 top panel provides easy access to all the connections. Please refer to Figure 2.1. (shown on
next page)
[1] AC INPUT connector :
This is a 3-pin male circular connector. A power cord is provided with the 6300. The circular connector end
of the power cord needs to be connected here. The power requirement of the 6300 is 90-260 VAC, 47-440 Hz
with a maximum power consumption of 100 VA (200 VA with heaters). The pin-out of this connector is
provided in Appendix C
Caution: Connecting incorrect power to the 6300 will cause considerable damage
[2] AC use :
A 5x20 mm fuse is located inside the fuse holder. This time-delay fuse, with a rating of 2.0 amps, 250 Volts,
limits AC power to the unit.
[3] AC On/Off switch :
This toggle switch connects (or disconnects) AC power between the AC INPUT connector and the 6300.
Even when this switch is ON, the 6300 becomes fully operational only after the Power key located on the
keypad of the Remote Unit is pressed for a minimum of 3 seconds.
When an internal battery is included, the battery-charging circuits inside the 6300 become active when the
AC On/Off switch is turned ON.
When internal heaters are included, the heater-control circuits inside the 6300 become active when the AC
On/Off switch is turned ON.
[4] Battery use :
This fuse is installed only if an internal battery is included. A 5x20 mm fuse is located inside the fuse holder.
This time-delay fuse, with a rating of 10 amps, 250 Volts, limits attery power to the unit.

6300 Rev H User’s Manual
125-9106A Page 10
[5] Battery On/Off switch:
This switch is installed only if an internal battery is included. This switch connects (or disconnects) the
internal battery from other circuits within the 6300. If AC power is not available, turning this switch On
allows the unit to operate on internal-battery power.
In situations where AC power may be intermittent, it is advisable to keep the attery On/Off switch in the
On position. This will allow the internal circuits to automatically switch to battery power when AC power is
lost.
Caution: When the unit is not being used, the Battery On/Off switch must be in the Off position.
Leaving this switch On will drain the battery since some internal circuits will be active when this switch
is On.
[6] Remote Unit connection:
Using the 30-foot remote cable, connect the Remote unit to the Main unit through this 10-pin circular
connector. It is recommended that this connection be made prior to applying power to the 6300. If this cable
is disconnected, the 6300 stops operating.
[7] Emergency Vent Valve, "Pitot Cross-bleed" :
In the event that the 6300 is in-operable due to a malfunction or due to loss of power, it is possible to vent the
Pitot system manually. This is done using the metering valve labeled “Cross-bleed”. This valve is a positive
shut-off valve. Opening this valve slowly will equalize the pressure between the Pitot and Static systems
(causing airspeed to be at zero).
Since opening this valve transfers pressure from the Pitot system into the Static system of the aircraft, while
opening this valve, care must be taken to vent the Static system simultaneously (if necessary), to prevent the
altimeter in the aircraft from going below minus-1000 feet. Also, care must be taken not to exceed the
maximum value of the Climb indicator in the aircraft.
Once airspeed is down to zero, this valve must be opened completely, to ensure that airspeed stays at zero
while the Static system is vented to ambient (using the Static vent valve).
Caution: This valve is for emergency use only and should not be used during normal operation. When
emergency venting is completed, this valve should be closed immediately.

6300 Rev H User’s Manual
125-9106A Page 11
Caution: This valve should not be tightened at all past its stop. It seals before it hits the stop. Even
finger-tight beyond the stop may damage the seat of the valve, causing it to leak constantly.
[8] Emergency Vent-Valve, “Static Vent”:
In the event that the 6300 is in-operable due to a malfunction or due to loss of power, it is possible to vent the
Static system manually. This is done using the metering valve labeled “Static Vent”. This valve is a positive
shut-off valve. Opening this valve slowly will vent the Static output of the 6300 to ambient pressure.
While venting, care must be taken not to exceed the maximum value of the Climb indicator in the aircraft.
Also, before venting the Static system to ambient, the Cross-bleed valve must be opened to ensure that
airspeed is zero.
Caution: This valve is for emergency use only and should not be used during normal operation. When
emergency venting is completed, this valve should be closed immediately.
Caution: This valve should not be tightened at all past its stop. It seals before it hits the stop. Even
finger-tight beyond the stop may damage the seat of the valve, causing it to leak constantly.
[9] Static port :
The Static port of the tester is provided with a #4-AN fitting. This port must be connected through a hose to
the Static port of the aircraft. The hose must be connected after performing the Self Test on the 6300. The
hose, once connected, must not be disconnected while the aircraft Static system is not at “Ground” level.
Caution: Do not connect the Static hose to the Static port before performing the Self Test.
Caution: Do not disconnect the Static hose from the Static port unless the aircraft Static system is at
“Ground” level and the tester has been turned Off.
[10] Pitot port :
The Pitot port of the tester is provided with a #4-AN fitting. This port must be connected through a hose to
the Pitot port of the aircraft. The hose must be connected after performing the Self Test on the 6300. The
hose, once connected, must not be disconnected while the aircraft Pitot system is not at “Ground” level.
Caution: Do not connect the Pitot hose to the Pitot port before performing the Self Test.
Caution: Do not disconnect the Pitot hose from the Pitot port unless the aircraft Pitot system is at
“Ground” level and the the tester has been turned Off.

[11] Indicator LED’s :
‘Ready’ LED: This green LED provides several indications as described below.
a. When the unit is ready for use, the LED is steadily On.
b. When the Remote is not connected, the LED blinks two times every 2-seconds
c. When the temperature is too low for operation (on units without heaters), the LED blinks once every
2-seconds.
d. After the unit is ready for use, when the Power key on the Remote is pressed, the LED blinks rapidly
while the Power key is held down. If the Power key is held down for more than 3 seconds, either a
turn-On or Turn-Off condition is ‘detected’ and the LED blinks slowly for 5 more seconds, during
which the user must release the Power key.
‘Heaters’ LED: On units equipped with internal heaters, this yellow LED will turn On while the heaters are
On. The LED may stay On even after the Ready LED comes On.
‘Low-Batt’ LED: On units with an internal battery, this yellow LED will turn On when a low-battery
condition is detected. After this LED turns On, the user will typically have 15 to 20 minutes before the unit
automatically turns Off due to total discharge of the battery. The Remote unit also displays a low-battery
condition as a warning message.
‘Charging’ LED: On units with an internal battery, this red LED will be On while the battery is being
charged.
[12] RS232 interface connector:
This connector is accessed by opening the “Interface Connectors” access panel. The connector is a standard
D -9 female connector used for a serial RS232 interface. It can be connected directly to the “COM” port of a
standard PC to allow communication. This port is normally used for downloading “profiles” from a
computer. Other remote communication with the 6300 is also possible through this interface.
For more details on downloading profiles, please refer to Section 4. For more details on communication with
the 6300, please refer to Section 8. The pin-out of this connector is provided in Appendix C.
[13] Encoder interface connector:
This connector is accessed by opening the “Interface Connectors” access panel. If the Encoder option is
included with the tester, this connector will interface to an altimeter encoder and enable the 10-bit Gray code
to be displayed on the Remote unit. For more details, please refer to Section 3.10.9. The pin-out of this
connector is provided in Appendix C.

[2] Pitot Actual value
The Actual value (actual pressure converted to selected units) being measured or controlled at the Pitot
output is displayed here in the selected Pitot units. The displayed resolution of this value depends on the
selected units and is shown in the table below. This Actual value is updated every 250 msec.
Pitot units Displayed
Resolution
knots 0.1
Mach 0.001
km/hr 0.1
mph 0.1
Pt inHg 0.001
Qc inHg 0.001
Pt mbar 0.01
Qc mbar 0.01

Qc psi 0.001
Pt mmHg 0.01
Qc mmHg 0.01
Pt kpa 0.001
Qc kpa 0.001
EPR 0.001
Important Note: When Pitot units are knots, km/hr or mph, and both ports are open to ambient, the
Actual airspeed value could be as high as +/-8 knots (instead of the expected 0 knots). This is still
within the specified accuracy of +/-0.003 inHg. Also, this does not mean that airspeed indications will
be off by +/-8 knots over the entire range of the airspeed indicator. Because of the extreme sensitivity
of airspeed to pressure at very low airspeeds, an error of 8 knots at ambient will translate to an error of
only 1.5 knots at 20 knots and only 0.6 knots at 50 knots. The error will decrease further as knots
increases.
[3] Pitot Target value
The target value that the user desires to achieve on the Pitot output is displayed here. When the Pitot
output is in Control mode, the 6300 will automatically adjust the Pitot Actual value to match the Pitot
Target value. The resolution of the Pitot target value is the same as the resolution of the Pitot Actual
value.
How the user can change the Pitot Target value is described in Section 3.4.

[4] Pitot-Rate units
The Pitot-Rate units are typically the Pitot units per minute. If Pitot units are knots then the rate units are
knots/min. However, there are three exceptions as shown in the table below. Pitot-Rate units cannot be
changed by the user.
Exceptions

[5] Pitot-Rate Actual value
The Actual rate of change of pressure at the Pitot output, converted to current Pitot-Rate units, is
displayed here. The displayed resolution depends on the Pitot-Rate units as shown in the table below.
The Actual Rate value is updated every 250 msec.
Pitot-Rate Units Displayed

psi/min 0.001
mmHg/min 0.01
kpa/min 0.001
[6] Pitot-Rate Target value
The rate at which the Pitot Target value ramps from one target to the next target, is determined by the
Pitot-Rate Target value. That is, if the Pitot-Rate target is set to 150 knots/min, and the airspeed (Pitot)
target is changed from 25 knots to 100 knots, the 6300 will ramp the airspeed at a rate of 150 knots/min,
taking roughly 30 seconds to move from 25 knots to 100 knots.
Note: On most aircraft, there is no indicator which displays this pitot-rate.
The Pitot-Rate target value has the same resolution as the Pitot-Rate Actual value. How to set the Pitot-
Rate Target is described in Section 3.5.

6300 Rev H User’s Manual
125-9106A Page 19
[7] Pitot Mode
The Pitot output can be in one of three modes: Measure, Leak or Control. The unit always powers-up in
Measure mode. The user must change to Control mode to move to a specific target. The user changes to
Leak mode (from Control mode) when performing a Leak check. After the Leak check is completed, the
unit automatically goes back into Control mode. So, during the entire operation of the tester, the user
should only stay between Control and Leak modes. The user should typically never have to go into
Measure mode.
How to change modes is described in Section 3.6 .
[8] Static units
The selected Static units are displayed here. There are 7 different Static units available.
1. Feet 3. inHg 5. psi 7. kpa

[10] Static Target value
The target value that the user desires to achieve on the Static output is displayed here. When the Static
output is in Control mode, the 6300 will automatically adjust the Static Actual value to match the Static
Target value. The resolution of the Static target value is the same as the resolution of the Static Actual
value.

How the user can change the Static Target value is described in Section 3.4.
[11] Static-Rate units
The Static-Rate units are typically the Static units per minute. If Static units are Feet then the rate units
are Feet/min. However, there is one exception as shown in the table below. Static-Rate units cannot be
changed by the user.

[12] Static-Rate Actual value
The Actual rate of change of pressure at the Static output, converted to current Static-Rate units, is
displayed here. The displayed resolution depends on the Static-Rate units as shown in the table below.
The Actual Rate value is updated every 250 msec.

[13] Static-Rate Target value
The rate at which the Static Target value ramps from one target to the next target, is determined by the
Static-Rate Target value. When units are Feet or Meters, this rate is the Climb-rate or Vertical Speed.
The Static-Rate target value has the same resolution as the Static-Rate Actual value. How to set the Static-
Rate Target is described in Section 3.5.
