Altimeter can be reset without a computer (as far as we indicated in the settings "Manual reset '
Yes'). We should wait until the LED will blink 3 times (if altimeter is not reset) and then short for
a moment two free contacts of the connector (marked in the figure as data contacts or reset). LED
will blink with single flashes.
Altimeter is ready for measurement. Reset by shorting the contacts does not erase the previous
measurement. The start of the measurement (indicated by 2 blinks) deletes the previous data.
Measurements are taken 15 seconds after disconnecting the battery or reset. They are not stored
in nonvolatile memory only in the so-called instantaneous. Only after the detection of previously
programmed measurement triggering value, the last 32 and current measurements are saved.
altitude measured before the launch is regarded as a reference, or the amount of '0 '. Start of
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. 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 measurement, altimeter
should be connected to the computer and
the handler started. After pressing the
"Altimeter Read” button, the data will be
read and illustrated in the chart. 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. In addition, the measurement can be transferred
directly to an Excel spreadsheet. The number of competitor, serial number and maximum height is
entered.
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.
