1. EAGLE TREE SYSTEMS Instruction Manual for the Altimeter MicroSensor V4 Document Version 1 2 Thank you for your purchase This instruction manual will guide you through the installation and operation of your Altimeter MicroSensor V4 the Altimeter Please read the entire manual carefully before proceeding If after you read the manual you have further questions or problems see the Support page on http www eagletreesystems com for additional information or email us at support eagletreesystems com Please visit our support web page for the full color electronic version of this manual which may be updated if changes were made after printing or if you want to view the manual on your computer Intended Uses The Altimeter is intended exclusively for recreational use in radio control models and model rockets Other uses are not supported Further using the Altimeter in situations where its use or failure could result in loss of life bodily injury or property damage is expressly prohibited What the Altimeter Does The Altimeter is a precision instrument that uses barometric pressure to measure altitude just as full sized planes do Advanced temperature compensation and factory calibration ensure the best possible accuracy with no user calibration required When used standalone the Altimeter displays your maximum altitude on the built in 7 segment LED display The maximum altitude continues to be updated and displayed on the LED until y2. reconnect it Once the desired units are configured disconnect from power and remove the wire jumper Then when reconnected to power the desired units should be displayed briefly 0 or 1 Reading Altitude in Standalone Mode When the Altimeter is powered on after the Units setting is displayed O or 1 the highest altitude attained during your last flight is repeatedly displayed one digit at a time on the LED For example if the highest altitude attained was 320 Feet 3 2 0 will flash repeatedly on the LED with a pause blank LED after the altitude is completely displayed but before it is displayed again To reset the max trigger just turn power off and on to the MicroSensor Then after landing from your next flight the highest altitude attained during that flight is displayed automatically overwriting the highest altitude from your prior flight even if the new highest altitude is less than the prior flight s highes altitude Note that an altitude of at least 60 Feet 18 Meters must be attained before a new highest altitude is displayed The highest altitude of your last flight 1s automatically saved so that when you turn the unit back on that altitude is displayed For example if you fly and reach a max altitude of 100 Feet when you land 1 0 0 will be displayed Then when you turn power off and on 1 0 0 will again be displayed If you then fly again an
