- Page 2 Paramaters Method of altitude measurement: measurement of pressure changes Measuring Range -500..9000 m Resolution 0.2 m Accuracy: 0,5 % (accuracy of measuring the difference of altitude) Supply Voltage: 3,6V to 6V Current consumption: 6,5 mA Sampling: 1 ÷ 2 sec / measurement 10 measurements / sec 15 measurements / sec 20 measurements / sec...
- Page 3 1. Introduction In accordance with the FAI recommendations, the measurement of altitude in the categories S1 and S5 is to be measured electronically with the use of altimeters. According to these guidelines altimeter has been developed, which in addition to measuring the maximum altitude, stores measurement results for the entire flight.

Page 4: Drivers Installing
4. Drivers installing Please install on the PC the USB drivers. The drivers can be downloaded from www.adrel.com.pl/download - file Altimetr_ProgramBMP.zip and unzip tem to any folder. For versions lower than programs 07.2010, you must copy the files from the folder …/Sterowniki_Builder/ to folder …/windows/system32. - Page 5 /raw - Windows XP and 2000 /w2k - only Windows 2000 /xpvista7 - Windows XP/Vista/7 x 32 /vista64 - Windows Vista x 64 And press ‘OK’ This brings up a warning message. Ignore it, or press "Continue Anyway". The driver will be installed. At the end choose "Finish". Then we need to check the COM port number at which the driver has been installed.
- Page 6 Vista x 64 Vista x64 does not accept unauthorized kernel-mode drivers. To use AVR-CDC on 64bit machine, you have to turn the "Driver Signature Enforcement" off by pressing the F8 function key during system boot up. "Driver Signature Enforcement Overrider" signs the driver as a Tested river and activates a test mode so you can load it without a real Signature.
- Page 7 checked - normally set to 7 meters). If a competitor delays the start, the whole flight may not be registered. 2. Sampling Frequency Acc. FAI rules, the measurement must be performed at least 10 times per second. Altimeter ALT-USB has the ability to set the measurement frequency. It is best to set 15 measurements per second.

Page 8: Altitude Measurement
In models of gliders, airplanes, just altimeter is placed inside the hull model. In models that do not have a closed hull, perform a separate container where you put altimeter. Connecting the battery Please pay attention when connecting the battery, the battery connector pins should be parallel to altimeter’s contacts. - Page 9 measurement (ie, exceeding the pre-programmed "altitude of the start of measurement") is signaled by double blink of diode. Current measurements are saved in memory. After a minimum of 2 seconds after the triggering of measurement altimeter verifies if the model is dropping. If it reached the altitude of less than 7m, and the model will not get lower, 32 more measurements will be taken, and the cycle is completed.

Page 10: Usb Adapter
Temperature correction Altimeter calculated height assuming the temperature, that was measured by the altimeter. However, in many cases, the temperature may differ significantly from the actual value. It is enough that before installation, altimeter is exposed to sunlight or a competitor will keep it in his hand. -
Page 11: Charging The Battery
10. Charging the battery Using adapter charger you can recharge rechargeable lithium-polymer (Pol Lid) batteries. There are available pin connectors where the battery should be connected. Charging is indicated by LED. When the LED is off charging is finished. As a source for supplying the charger you can use any computer, connecting the adapter to the USB connector.
