This altimeter has been designed for measuring and recording altitude data in model aircraft. A complete altimeter package currently consists of three parts: the altimeter itself, a 10 foot cable to connect the altimeter to your computer's serial port, and a Windows application used for viewing and storing flight data on your computer.
For model airplane use, the altimeter plugs into an unused channel on your receiver for power. When power is turned on to your system, the altimeter will go through a 2 minute waiting period to allow the semiconductor pressure sensor to settle. This is unfortunately unavoidable due to the extremely small pressure variations that the altimeter is measuring. After this 2 minute period, the altimeter will beep 3 times to notify you that it is taking data, and you may begin your flight. Data will continue to be taken until power to the altimeter is removed. Every time power is re-applied to the altimeter it will begin storing data under a new flight. This can continue until the 4-1/2 hours of memory is full. So, for example, you could have one long 4-1/2 hour flight, or nine 1/2 hour flights, or eighteen 15 minute flights, etc.
For recreational use, the altimeter may be powered by a standard 9 volt battery. It may be used to record altitude information on a hike or a drive to the mountains.
