The MU-9000X USB is an absolute inclinometer utilizing MEMS (micro electro-mechanical systems) technology to sense tilt angles over a full 360° range in 2 axes. The MU-9000X USB incorporates a number of patent pending breakthroughs to create a new type of inclinometer that is rugged, compact, fast, lightweight and easy to use. The MU-9000X USB represents leading-edge advancement is MEMS technology and is the most advanced device available for radio control aircraft setup.
A USB to RS232 interface is included which facilitates communication between the MU-9000X USB and the pilot's computer / software. The interface is USB 1.1 and 2.0 compatible and the included 6-foot cable is ROHS compliant. Configurations and parameters are stored in non-volatile memory within the MU-9000X measuring unit and include level, resolution, damping / averaging time, and direction. Damping is the amount of time over which angle readings are averaged and is adjustable according to user preference from 2 to 5000 milliseconds.
The MU-9000X USB software runs on laptop or desktop computers running either Windows Vista, Windows XP or Windows 7. A minimum of 5.83 Mb of disk space is required.
Please CLICK HERE to see an instructional video that gives details about how to setup your ailerons, elevators, rudder and engine thrust angle.
Measured Angle Frame, Measurement Frames 1 and 2: This frame shows the measured angle. The angular range is +/- 180 degrees (360 degrees total).
Large Digit Display Button: When selected, the display shows the measured angles for both Measurement Frame 1 and 2 in Large Digits. Can be selected from either Measurement Frame 1 or 2. To return to the main screen, click on the "Back to Main Screen" button.
Zero Button, Measurement Frames 1 and 2: When selected, the Measured Angle Frame is set to zero degrees. This relative zero can be set at any angle.
Level Button, Measurement Frames 1 and 2: When selected, the software reads the factory-calibrated level. Now, when the Measured Angle Frame reads zero, the measurement plate is level.
+ Target / - Target, Measurement Frames 1 and 2: These frames hold the desired or "target angles". When the angle shown in the Measured Angle Frame equals the "target angle", the corresponding color bar illuminates green. The angles within the +/- Target Frames can be keyed in manually or the angles can be loaded in automatically using the "Conversion Utility" (see below). Be sure to key in the minus (-) sign when entering negative numbers.
Target Tolerance Drop-down Menu, Measurement Frames 1 and 2: The angle selected in this menu determines how close the measured angle must be to the "target angle" before the corresponding color bar illuminates green. For example, if .25 degrees is selected and +22.00 and -22.00 are chosen to be the "target angles", then the angle ranges that will cause the two color bars to illuminate green are +21.75 to +22.25 AND -21.75 to -22.25, respectively.
Axis Select Drop-down Menu, Measurement Frames 1 and 2: Either Measurement Frame (1 or 2) can be set to Axis 1 or 2.
Picture Drop-down Menu, Measurement Frames 1 and 2: Either "Pitch" or "Roll" can be selected as the Measurement Frame Picture. The "Pitch" and "Roll" pictures appears as either an airplane or a representation of the disk-shaped measurement device. Either airplane or device can be chosen from within the "View" menu.
Invert Button, Measurement Frames 1 and 2: When selected, the polarity of the Measured Angle frame changes. The Pitch or Roll picture will also rotate in the opposite direction when "Invert" is selected. This feature allows the USB cable to more easily egress in a desired / convenient direction.
Convert Button, Measurement Frame 1: This conversion utility allows control surface deflection that has been specified in inches, to be converted to degrees. Simply enter inches (or millimeters) of control surface movement into the right (+deflection) and left (-deflection) entry boxes, enter the width of the control surface into the center entry box (chord), and click the "Convert" button. Inches (or millimeters) are converted to degrees and loaded into the -/+ Target frames above. For more details about converting from inches to degrees, please visit our Tips Page.
+/-90 Degree Buttons, Measurement Frame 1: This feature facilitates convenient measurement of engine thrust angle. Similar to the "Zero" button (sets Measured Angle to 0.00), this button sets the Measured Angle to +/-90.00 degrees. The +/-90.00 Degree reference is usually set when resting on a longeron in preparation for measuring engine thrust angle (Up/Down). If there is no up/down thrust angle set in the airplane, then the Measured Angle will read 0.00. If there is some up/down thrust set in the airplane, then that angular measurement is read directly without having to add or subtract 90 degrees from your measurement. The +/-90.00 Degree reference can also be set in preparation for engine thrust angle (Left/Right). The fuselage is placed on its side with the reference taken from the firewall and the measurement made on the engine shaft. See the Tips Page for more tips on measuring engine thrust angle.
Damping Drop-down Menu: Adjustable from 2 to 5000 milliseconds, this sets the amount of time that the software averages the hundreds of angle readings per second. In a mechanical inclinometer, the arm and counter-weight that seeks the lowest point can be thought of as a pendulum. It is important to dampen the pendulum's oscillations so that a stable angle measurement can be made. 500mS (1/2 second) is a good initial setting.
Save to File: Selecting this allows pilots to keep track of each AeroPerfect™ configuration. Examples of configuration names: "GP Extra 300 Left Aileron" or "Pitts Python Upper Wing Incidence". Files can be saved as .CFG or .TXT. "TXT" is best when sharing configurations by e-mail with other pilots. The name of the configuration file just saved is displayed at the top (to the right of the "View" menu).
Open File: Selecting this allows pilots to load previously saved configurations. The name of the configuration file currently loaded is displayed at the top (to the right of the "View" menu).
Temperature: This displays the temperature of the MU-9000X measuring device. It is displayed in Celsius and Fahrenheit and reflects the internal temperature of the device. It is always a bit higher than ambient as there is a small amount of device self-heating.
Current Software Version: This is displayed at the very top of the application.
Connection Status: Shown just below "Current Software Version", this shows whether or not the MU-9000X is communication with your computer. When connected and communicating, it will show which COM port is being used. When not connected / communicating, the message, "Not Connected" is shown and the application is replaced by an aqua color field.
View Menu: The "View" menu provides a link to this web page and also provides a way of changing the Device Picture (i.e., airplane or disc).
Upper, Right-Hand Button: This exits the application when selected.
