be taken, and the cycle is completed. The end is signaled by three blinks of LED (as in the absence
of zeroing). You can disconnect the battery and connect the altimeter to the computer to read data.
If the end of the measurements was not detected automatically, you must short the contacts for
a while (like the return to zero). The measurement is completed

Reading of measurements.
After the flight, check if it has been measured. Start of measurement is indicated by two blinks
of the diode. The end of the measurement (detection of land level or the end of memory) is
indicated by a three blinks of LED. However, if after the flight the LED blinks twice, it means that
level of the landing has not been detected -
but the measurements were made. You can
disconnect the battery – until this time
measurements were recorded in the
memory. When connected to a computer,
the altimeter’s LED should blink three or
four flashes (this depends on the parameter
settings "reset manually - as described
above). This means that the measurement
was registered. After pressing the "Read
altimeter" measurements will be read and
displayed on the screen.
On the right side maximum and
minimum altitude will be displayed. In the
"contestant" window the number of
competitor and the serial number will be
displayed.
Read data can be saved on your computer HDD by pressing "Save" in the panel "Drive - Read /
write. Such recorded data can be played back at any time. Altimeter does not need to be connected.
The program can read the current temperature measured by the altimeter.
The graph can be zoomed. Use your mouse to mark the
interesting part of the chart. During
zooming it is important to mark from left
to right. Any selection from right to left
returns to the view
of the entire chart.
Below are the charts
after the increase.
Graphs of the flight can be compared with each other. To do
this, read data from altimeter or disk, and then click
"Compare". This brings up a file selection window. Please
select a file with data to compare and click 'Open'. An
additional chart appears on the screen. Speed chart and
comparisons can be switched off in the menu tab "Charts"
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
