  • Page 8: Introduction

    The model 6300 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 is ready for use. It’s high accuracy and ease of use make it the ideal Pitot Static Tester.

  • Page 9: Controls And Connections

    Remote Unit connection: The 6300 is provided with a 50 foot remote cable to connect to the Remote unit. The male end of the remote cable is connected here on the top panel. The female end of the remote cable is connected to the Remote unit.
  • Page 12 The remote cable is normally left connected to the 6300 at the “Remote” connector on the top panel and is wrapped around four cord posts on the lid of the 6300 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.
  • Page 13 [10] 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.
  • Page 14 [11] Pitot 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 Pitot system manually. This is done using the metering valve labeled “Pitot Vent”. This valve is a positive shut-off valve. Opening this valve slowly will vent the Pitot output of the 6300 to ambient pressure.

  • Page 26 Static half Units: knots Feet/min Feet Actual: 101.2 3500 1005 Target: 20.0 3000 The Main operating screen will be used almost all the time during normal operation for commanding target values, viewing actual values, setting units and modes. Error Messages: The Main screen is also used to display error conditions as they occur.

  • Page 27: Target Value Entry

    Pitot target value : A Pt or airspeed target value can be entered using the Pt/AIRSPEED key. On pressing this key the target value field for Pt gets put into reverse video. The 6300 is now awaiting numeric entry from the operator. While this new value is being entered, the old target value is still effective and does not in any way affect the Pitot output.
  • Page 28 Remote unit and the main unit. Please abort and contact the factory. If GO is pressed after ENTERing the value, the 6300 will try to achieve this new target value ONLY IF the Pitot output is in the CONTROL mode. Therefore, it is desired that both Pitot and Static values be entered so that both are blinking before the GO key is pressed.

  • Page 29: Units Selection

    Target Value Jog Each of the three target values can be jogged up or down in small increments by using the arrow keys. This is done to help the operator achieve a perfect reading on the instrument in the aircraft, by bumping the set-point in small increments. To jog a value, select the value by pressing the appropriate target value key and then use the arrow keys.
  • Page 30 Target: 0.064 3000 The unit selection will not become effective until the GO key is pressed. The 6300 will return to the old units if the CANCEL key is pressed. . Static Units: There are four Ps units to choose from: Feet, Ps inHg (Psin), meters, and mbar (Psmb).

  • Page 31: Mode Selection

    10.000 29.054 The unit selection will not become effective until the GO key is pressed. The 6300 will return to the old units if the CANCEL key is pressed. . It must be noted that the units change does not perform a conversion between the units of feet/minute or meters/minute to Ps inHg/min or Ps mbar/min.
  • Page 32 Units: knots Feet/min Feet Actual: 101.2 3500 1005 Target: 20.0 3000 Pt mode : MEAS, LEAK, CTRL Move the cursor to the desired mode and then press ENTER. The selected mode is displayed on the screen and blinks until the GO key is pressed. The new mode will not become effective until the GO key is pressed.
  • Page 33 This process is termed as Equalization. While the 6300 is undergoing this process, the term 'EQZN' is displayed on the main screen in place of the “Actual” value. The whole process usually takes about 15 seconds or less to complete.

  • Page 34: Leak Screen

    6300 can automatically adjust the gain of it’s control mechanism. Due to this, the actual value will always increase in both altitude and in knots for about 5 seconds, regardless of the target value. Once this process is complete, the actual values will move towards the target values.
  • Page 35 Pressing the CANCEL key allows you to exit from the Leak Screen, back to the Main Operating Screen. If the mode prior to entering the Leak mode was Control then the 6300 will revert back to Control mode on exiting the Leak Screen.

  • Page 36: Timed-Leak Screen

    3.3.1 TIMED-LEAK SCREEN When both Pitot and Static outputs are simultaneously put into Leak mode, then the leak screen displays the leak values in a timed-leak format as shown below. The sample screen shown below assumes the following: a. Units are set to knots and feet b.
  • Page 37 To accept the setting of the 1 leak-timer and move the arrow to the 2 leak-timer, press ENTER. The screen will appear as below. Change the 2 leak-timer value if desired, using the Arrow keys. The leak-timer value must be changed before the elapsed time reaches 58 seconds.
  • Page 38 updated and appear as shown below. The second line shows that at the end of 1 minute the knots value leaked to 99.5 knots and the accumulated leak in 1 minute was -0.5 knots, since the knots value at the start of the leak check was 100 knots. The second line also shows that at the end of 1 minute, the altitude was at 14965 feet and the accumulated leak in 1 minute was - 35 feet, since the altitude was at 15000 feet at the start of the leak check.

  • Page 39: Self Test Screen

    SELF TEST SCREEN As part of the start up procedure, it is recommended that a Self Test be performed on the 6300. Before performing the Self Test you must follow the start up procedure explained in section 3.1. The Main Operating Screen must be displayed on the Remote unit. There should be no errors displayed on line 4 of the display.

Pump section OK Ps control system OK Pt control system OK. Tests successful. After the tests have been completed successfully, press the CANCEL key to return to the Main Operating Screen.

  • Page 41: Function 0: Ieee Address

    3.5.0 FUNCTION 0 : IEEE ADDRESS This function allows the user to enter a valid IEEE-488 address for the 6300. This address is meaningful only if the “IEEE” option is provided on the 6300. A valid address between 1 and 30 may be entered on the screen shown below.

  • Page 42: Function 2: Set Limits

    If the target value exceeds any of the limits, an error is generated. The Actual values are also checked when the 6300 is in the “Control” mode. If any of these limits is exceeded by a pre-defined amount, an error will be generated and the 6300 will revert to “Measure” mode.

  • Page 43: Function 3: Set Knots Rate

    typical setting for this limit is 1.0. 4. Max. Feet : This limit is usually set to the maximum altitude that the aircraft instruments can tolerate. The maximum value is 80,000 and the minimum is 0. A typical setting for this limit is 50,000. 5.

  • Page 44: Function 4: View And Execute Profiles

    This indicates that the current profile point is ready for execution and awaiting the “GO” key to be pressed. When the “GO” key is pressed, the 6300 will execute the profile point, i.e. it will change to Control mode and move towards the desired targets.

  • Page 45: Function 5: Setup Profiles

    3.5.5 FUNCTION 5: SETUP PROFILES This function is used to load profiles into the 6300 from a PC. A full explanation of how to load profiles into the 6300 is provided in Section 4.. The following screen will come up when Function 5 is selected.

  • Page 46: Function 8: Go To Ground

    “memorized” in the “Set Ground” function and the target airspeed is set to 20 knots and the 6300 ramps towards these targets. Once these targets have been achieved, you must put the 6300 into Measure mode on both outputs and only then disconnect the 6300 from the aircraft.
  • Page 47 If an altitude encoder is electrically connected to the Encoder interface conneector on the top panel of the 6300-M3 (under the Interface Conncectors panel) and is pneumatically connected to the Static output of the 6300-M3, then 10-bit code on line 2 and flight level on line 3 will correspond to the altimeter reading.

  • Page 48: Profiles

    4.1 WHAT IS A PROFILE. A profile is a set of up to 50 points that tell the 6300 what you would want it to do at each point. Each point consists of 7 parameters: 1) Pitot units, 2) Pitot mode, 3) Pitot target value, 4) Static units, 5) Static mode, 6) Static target value and 7) Static rate (Climb) target value.
  • Page 49 Rate target value In the sample profile, Row 3, which is the first point in the profile, tells the 6300 to go in Control mode to 100 knots on the Pitot side, and in Control mode to 0 feet at 6000 feet/min on the Static side.

  • Page 50: Creating A Profile

    12 characters. On Row 2, middle cell, replace “11” with a profile number between 1 and 20 that you would like this profile to be saved as, in the 6300. Do not change row 2 right-most cell. In rows 3 through 50, change the cells as per the points you want to generate in your test.

  • Page 51: Setting Up Hyperterminal

    Your profile has been created. 4.3 SETTING UP HYPERTERMINAL You download a profile into the 6300 using the Hyperterminal program. At first you need to setup Hyperterminal. You only need to do this once.
