  • Page 18: Main Operating Screen

    Function Select screens are used only a few times during normal operation and also when first setting up the 6500-HA. The Calibrate screen is used only once a year by the calibration facility. During normal operation, the two screens that are used the most are the Main Operating screen (Main Screen) and the Leak Screen.
  • Page 19 The two values (1005 and 0) that appear below it are in these units. Units: knots Feet/min Feet Actual: 101.2 3500 1005 Target: 20.0 3000 Parameter 3. Climb Units: Unit of measurement for displaying the rate of change of the Static output, or Climb.
  • Page 20 This is the value that you command the 6500-HA to achieve on the Pitot output (Pt test port). In the sample screen below, the 6500-HA has been commanded to achieve a pressure of 20.0 knots on the Pitot output.

  • Page 23 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 24: Target Value Entry

    Use the numeric keys to enter the value. Use the +/- key to change the sign of the value. The 6500-HA will beep on every key entry, and it will beep for a longer time period if extra invalid digits are entered. It is not necessary to enter the decimal point and the digit after the decimal point if that digit is “0”.
  • Page 25 Remote unit and the main unit. Please abort and contact the factory. If GO is pressed after ENTERing the value, the 6500-HA 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 26: 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 27 Target: 0.064 3000 The unit selection will not become effective until the GO key is pressed. The 6500-HA 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 28: Mode Selection

    10.000 29.054 The unit selection will not become effective until the GO key is pressed. The 6500-HA 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 29 4 of the display, with the cursor under “MEAS”. 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.
  • Page 30 Since the controlling portion of the 6500-HA is isolated from the output during Measure or Leak modes, it will usually be at a pressure quite different from that at the output. Simply introducing the controlling section into the pneumatic system connected to the output will cause a surge in pressure (or vacuum) at the output.

  • Page 31: Leak Screen

    Following the Equalization process, only when the actual value on the Static output is less than 2000 feet from Ground and the Pitot output is less than 150 knots, the 6500-HA will automatically inject a small vacuum on the Static output and a small pressure on the Pitot output.
  • Page 32 Until the first minute has elapsed it shows “WAIT”. While in the Static Leak Screen, if the leak ever exceeds 2000 ft/min, the 6500-HA will automatically trip out of the Leak mode and revert back to Control mode. It will then display a message as follows: Static leak exceeds 2000 ft/min.

  • Page 33: Timed-Leak Screen

    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 6500-HA will revert back to Control mode on exiting the Leak Screen.
  • Page 34 100.0 knots 0 ft/min. 15000 feet 0:00 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 35 How the Timed-Leak screen is updated: The first line of the screen, which shows the current Actual values, is updated every 0.25 seconds. The elapsed time is updated every second. Assuming that the leak-timers are set to 1, 2 and 3 minutes, when the elapsed time reaches 1:02 (2 seconds after the elapsed time reaches the first leak-time) , the leak screen will be updated and appear as shown below.

  • Page 36: Self Test Screen

    As part of the start up procedure, it is recommended that a Self Test be performed on the 6500-HA. 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.

  • Page 38: 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 6500-HA. This address is meaningful only if the “IEEE” option is provided on the 6500-HA. A valid address between 1 and 30 may be entered on the screen shown below.

  • Page 39: 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 6500-HA is in the “Control” mode. If any of these limits is exceeded by a pre-defined amount, an error will be generated and the 6500-HA will revert to “Measure”...
  • Page 40 this limit is 500.0 2. Min. knots : This limits is usually negative and it defines the maximum “Negative Qc” that the airspeed instruments (UUT) can tolerate. In most cases it should be set to about “-200.0” since almost all airspeed indicators can tolerate at least that much negative Qc. Setting it any closer to “0.0”...

  • Page 41: Function 3: Set Knots Rate

    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 6500-HA will execute the profile point, i.e. it will change to Control mode and move towards the desired targets.

  • Page 42: Function 5: Setup Profiles

    3.5.5 FUNCTION 5: SETUP PROFILES This function is used to load profiles into the 6500-HA from a PC. A full explanation of how to load profiles into the 6500-HA is provided in Section 4.. The following screen will come up when Function 5 is selected.

  • Page 43: Function 7: Set Ground

    The “Set Ground” function is used to indicate to the 6500-HA the ambient “Ground” pressure. Before connecting the 6500-HA to the UUT, just after the Self Test has been performed, it is recommended that this function be invoked. The Pitot and Static ports must still be open to ambient when using this function.

  • Page 44: Function 9: Encoder

    If an altitude encoder is electrically connected to the Encoder interface connector on the rear panel of the 6500-HA (not shown in Fig. 2.2) and is pneumatically connected to the Ps output of the 6500-HA, then the 10-bit code on line 2 and flight level on line 3 will correspond to the altimeter reading.

  • Page 45: Profiles

    4.1 WHAT IS A PROFILE. A profile is a set of up to 50 points that tell the 6500-HA 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 46 Rate target value In the sample profile, Row 3, which is the first point in the profile, tells the 6500-HA 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 47: 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 6500-HA. 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.
