  • Page 34: Measure To Control Transition

    To prevent such a surge, the 6300 measures the pressure at the output, shuts-off the output from the internal 6300 pneumatics, and then controls the pressure within the internal control mechanism to match the pressure at the output.

  • Page 35: Leak Checks

    Leak checks can be performed either independently or simultaneously on the Pitot and Static outputs of the 6300. The ideal way to perform leak checks is to put only one output in Leak mode while keeping the other output in Control mode. However, if necessary, both outputs can be simultaneously put into Leak mode.

    6300 for up to 8 hours. The battery can be recharged simply by connecting AC power to the 6300 and turning On the AC On/Off switch. It is not necessary to turn On the Battery On/Off switch during charging.

  • Page 54: Leak-Checking The 6300

    6300 contributes less than 10% to the leak with the aircraft connected. Therefore, an internal leak of 100 ft/min in the 6300 will contribute only 10 ft/min (or less) to the leak measured with the aircraft connected.

  • Page 55: Section 4 : Profiles

    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 8 parameters: 1) Pitot units, 2) Pitot mode, 3) Pitot target value, 4) Pitot Rate target value, 5) Static units, 6) Static mode, 7) Static target value and 8) Static Rate target value.
  • Page 56 Static 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 at 150 knots/min on the Pitot side, and in Control mode to 0 feet at 6000 feet/min on the Static side.

  • Page 57: Creating A Profile

    On Row 2, middle cell, replace “11” with a profile number between 1 and 15 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. For entering Units and Modes use the drop down menu selections for those cells.

  • Page 60: Section 5 : Typical Use

    If the targets are not achieved, or if the Actual values are fluctuating, then this indicates that the Pitot or Static system is open to ambient and is unable to achieve the targets. Turn Off the 6300 and fix the problem before proceeding.

    6300 TRANSDUCERS Pitot Transducer The Pitot output of the 6300 has a differential transducer with a range of 0 to 30 inHg differential. The differential pressure is measured with the pressure at the Static output as the reference. This transducer must be calibrated at 0 inHg differential and 30 inHg differential (with respect to Static).
