The MU-9000X 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 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 represents leading-edge advancement is MEMS technology and is the most advanced device available for radio control aircraft setup. Configurations and parameters which are stored at the factory in non-volatile memory include level, resolution, damping / averaging time, and direction. Damping is the amount of time over which angle readings are averaged and has been factory set to 500 milliseconds. |

The AP3 is a digital LCD readout designed to display the incremental count value of the MU-9000X. The AP3 features a sign indicator for displaying both positive and negative angles. Signals from the MU-9000X are filtered by the AP3 to ensure signal integrity over the entire input frequency range. The Match LED illuminates and relay closure occurs when an encoder count equals the zero angle. Under normal operation the relay closure feature is not needed. However the modeler may want to connect an external light or audio enunciation indicating zero angle has been reached. Please refer to the mechanical drawings and electrical specifications for proper implementation of this feature. Note that any angle reported by the AP3 can be reset to a zero reference angle. The AP3 Digital Display is powered by the AP12, +12 Volt power supply (included- see below). Optionally, the display unit accepts power from an external battery through a standard 2.1mm DIN circular plug (see FAQ Page for further details). The AP3 Digital Display supplies the +5 VDC power for the MU-9000X. Whenever the preprogrammed limits of +/- 0.5 degrees are exceeded, the AP3 digital display illuminates a corresponding High or Low LED. This feature is quite useful since it lets the user know when the angle is approaching zero. The AP3 is constructed of a lightweight high impact polymer case with a clear viewing window. The AP3 display offers 0.5" high digits with blue backlighting. Leading Zero Blanking provides superior readability! (New, October 2006). The AP3 front panel thickness may range up to a maximum of 0.125" thick. |

Note: It is very important that care be exercised when opening the case. Do not touch any of the electrical components as static discharge can damage them. Do not force the AP3 into an undersize cutout or over-tighten the screws when reinstalling the case. Damage resulting from improper installation is not covered under the terms of the AeroPerfect™ Warranty. |

The AP-12 is an 18W regulated switching power supply that provides 12VDC @ 1.5A output. The power supply covers voltage inputs ranging from 90 to 264VAC and 47 to 63Hz which accommodates most international power requirements. Typical efficiency is 70% and output is short circuit protected. The power supply DC output uses a 2.1mm circular plug (center positive) which is attached to a 48 inch long cable. The power supply plugs directly into a standard 120VAC receptacle or the appropriate AC plug adapter (see below). |
