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.  The   measured   temperature   may   then   vary   up   to   several   degrees   C.   The   difference   in 
calculating the amount of approximately 0.3% per degree C. For example, height of 355.5 meters 
at 24 C, after correction for 20 C temperature is 350.7 (the difference of 4,8 meters). 
In the handling software of the altimeter (from version 5.2010), temperature correction is possible. 
After typing in the "Temperature" field of the new value and pressing "Enter" key, measurements 
will be re-converted and displayed. It is recommended that the start cards had additional line, 
which keeps the ambient temperature. 

Filter

      If the altimeter was not properly mounted and subjected to a direct effect of air flow, it also 
works on its dynamic pressure, which distorts the measurements. Also wind gusts interfere. The 
graph can be seen as a clear "pin", which differ substantially from the correct chart. You can then 
use a filter that removes these erroneous measurements. The measurements are filtered multi-
stages.   First,   discard   the   "pins".   He   then   calculated   the   average   and   again   rejected   the 
measurements are wrong, but taking into account this average. The result is as smooth graph. 
     The data read from the altimeter, or read from the disk can be filtered in using 

Filter

 button on 

the left side of the screen.
         Data  for  comparison,  can  be  filtered   using the  button   at  the  

Filter

,  which   is under  the 

"Compare" button.
      After filtration, two graphs are drawn - before and after filtration. By clicking the left mouse 
button on the chart, you can delete it. When you change the parameter settings of the filter can 
filter out the data again, no need in re-load measurements. 
Filter parameter can be set settings tab in the Filter

The "altimeter" has its own instructions. Is displayed when you press "Help"

    9. USB Adapter

     As described earlier, to connect the altimeter 
to a computer you need a special adapter. There 
are offered two types of adapters: with charger 
and without t charger. You can also try to make 
cable for connecting the altimeter yourself. To do 
this in a typical USB cables cut off one plug 
(leave the plug connected to a computer) and 
isolate the wire length of approximately 1.5 cm. 
Then color-coded wires as in the photo should be 

soldered (or tightened) to the appropriate connector pins. Please note that the pin spacing is 2mm. 
Below are listed the addresses of shops and types of connectors needed for the implementation of 
the cable. Free contact must be filled  so that one could not connect the altimeter in the opposite 
way.
