SECTION 1
INTRODUCTION
Note: Pt = Pitot and Ps = Static
The model 6300-M3 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 and mbar. The 6300-M3 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-M3 has two high accuracy transducers that measure pressure in the range of 0 to 38
inHg absolute on the Ps (static) output, and 0 to 100 inHg absolute on the Pt (pitot) output.
These transducers are designed to accurately measure the pressure of dry air over an ambient
temperature range of -40
o
C to 55
o
C. The 6300-M3 is RVSM compliant.
The 6300-M3 allows the user to control altitude in feet or meters, climb in feet per minute or
meters per minute, airspeed in knots, mach, mph and kmph. It also allows the user to control
EPR on the pitot output.
The model 6300-M3 features programmable limits on altitude, airspeed, 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-M3 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 pushing the 'GO' button. Up to 50 points can be stored in
one profile. The 6300-M3 can store up to 20 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-M3.
The model 6300-M3 comes with an RS232 interface. This interface is mainly used to download
profiles from a computer. Connect Power and the Remote, connect the Pitot and Static outputs
to the aircraft, and the 6300-M3 is ready for use. It’s high accuracy and ease of use make it the
ideal Pitot Static Tester.

is connected to the Remote unit. This cable should be connected prior to applying power to
the 6300-M3. This cable should not be disconnected while power is applied to the 6300-M3.
The remote cable is normally left connected to the 6300-M3 at the “Remote” connector on the
top panel and is wrapped around four cord posts on the lid of the 6300-M3 case. The cord
retainers on top of these posts swivel in either direction and latch at 180 degree positions,
allowing easy wrapping and unwrapping of the remote cable. A cord clamp allows the cable
to be held in place after it is wrapped. It is easier to wrap the remote cable around the posts
after disconnecting the cable from the Remote unit.
If the remote cable needs to be disconnected and removed from the 6300-M3 completely for
storage elsewhere then opening the Interface Connectors cover allows the cable to be
dislodged from the cable guide.
[8] Static ports :
The Static output is provided on two ports that are internally connected. Both ports have #6-
AN (or #4-AN) fittings. At least one of these ports must be connected through a hose to the
Static port on the aircraft. The hose must be connected after performing the Self Test on the
6300-M3. The hose, once connected, must not be disconnected while the aircraft Static system
is not at “Ground” level. An unused port must remain closed.
Ca tion: Do not connect the Static hose to the Static port before performing the Self
Test.
Ca tion: Do not disconnect the Static hose from the Static port nless the aircraft Static

system is at “Gro nd” level.
[9] Pitot ports :
The Pitot output is provided on two ports that are internally connected. Both ports have #4-
AN (or #3-AN) fittings. At least one of these ports must be connected through a hose to the
Pitot port on the aircraft. The hose must be connected after performing the Self Test on the
6300-M3. The hose, once connected, must not be disconnected while the aircraft Pitot system
is not at “Ground” level. An unused port must remain closed.
Ca tion: Do not connect the Pitot hose to the Pitot port before performing the Self Test.
Ca tion: Do not disconnect the Pitot hose from the Pitot port nless the aircraft Pitot
system is at “Gro nd” level.
[10] RS232 interface connector:
This connector is accessed by opening the “Interface Connectors” access panel. The
connector is a standard DB-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-M3 is also possible through this interface. igure 2.2 shows the RS232 connector
with the panel removed. or more details on downloading profiles, please refer to Section 4.
or more details on communication with the 6300-M3, please refer to Section 8.

In the event that the 6300-M3 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”, located on the top panel, to the left of the DC On/Off switch. This valve is a
positive shut-off valve. Opening this valve slowly will vent the Static output of the 6300-M3 to
ambient pressure. While venting, care must be taken to ensure that the maximum climb rate
of the aircraft connected to the tester is not exceeded. Also, the Pitot Vent may need to be used
to maintain the airspeed within limits of the indicator on the aircraft.
Ca tion: The Static Vent is NOT connected to the Pitot Vent. There is NO cross-bleed.
When venting is completed, close the valve.
Ca tion: Do not over-tighten the valve as this may damage the seat of the valve.
[13] Pitot Vent :
In the event that the 6300-M3 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
“Pitot Vent”, located on the top panel, to the left of the DC use. This valve is a positive shut-
off valve. Opening this valve slowly will vent the Pitot output of the 6300-M3 to ambient
pressure. While venting, care must be taken to maintain the airspeed within limits of the
indicator on the aircraft.
Ca tion: The Pitot Vent is NOT connected to the Static Vent. There is NO cross-bleed.
When venting is completed, close the valve.
Ca tion: Do not over-tighten the valve as this may damage the seat of the valve.
[14] Indicator LED’s :
Two indicator LED’s are provided just to the left of the Pitot port. The READY LED is green
and turns ON when power is connected to the 6300-M3 and the unit is ready for use.
The HEATERS LED is yellow and turns ON when the internal heaters are energized.
When power is turned ON using the AC or DC On/Off switch, at least one of the two LED’s
will turn ON. If only the HEATERS LED is ON then the unit is warming-up and is not yet
ready for use. The unit will be ready for use only after the READY LED turns ON. It is
possible that at certain times both LED’s will be ON.
When the READY LED is ON, the unit is functional only after the On/Off switch on the
Remote Unit is turned ON.

SECTION 3
UNDERSTANDING THE 6300-M3
Note: Pt = Pitot and Ps= Static
The 6300-M3 is typically used to calibrate and check air data instruments like altimeters, climb
indicators, and airspeed/ Mach indicators on an aircraft. It is also used to leak-check the
Pitot/ Static system of an aircraft. This section will explain how to use the 6300-M3 to perform
these functions.
3.1 START UP
Step 1: Connect the Remote cable to the Remote unit and the “Remote” connector on the
main unit.
Step 2: Check the ON/O switch on the Remote unit and make sure it is O .
Step 3: Remove the protective caps from one each of the Pitot and Static outputs on the
main unit. DO NOT connect any hoses yet. Make certain that the outputs are
open to ambient. Close Pitot and Static Vent valves.
Step 4: Connect the power cable to the “AC INPUT” connector on the main unit and
connect the far end of the power cable to an AC supply.
Step 5: On the Main unit, turn the AC On/Off switch ON. On the Remote unit, turn the
ON/O switch ON.
The 6300-M3 will turn ON and the Remote unit will turn ON. The display will briefly show
the sign-on screen and then go into the Main screen. The Main screen should appear as
follows:
Units: knots Feet/min Feet
Actual: M 101.2 3500 1005 M
Target: 20.0 3000 0
The Actual values shown on line 2 will be different from the ones shown. The 4th line should
be blank.
Before actually using the 6300-M3 to perform certain tasks, it is important to understand how
to use the Remote unit to make the 6300-M3 do what you want. This section explains
