The vario time and date are automatically synchronized with the GPS data at the instrument’s power on.
To set the time zone for your country go to (MAIN SETUP \ n. 7 UTCO).
To manually adjust the time and date, go to (MAIN SETUP \ n. 8 HOUR), (MAIN SETUP \ n. 9 MIN), (MAIN
SETUP \ n. 10 DAY), (MAIN SETUP \ n. 11 MONT), (MAIN SETUP \ n. 12 YEAR).

PILOT’S NAME & GLIDER’S DATA
To set the pilot name, the glider type and the glider id, go to (MAIN SETUP \ n. 17 PILO), (MAIN SETUP \ n. 18
GTYP), (MAIN SETUP \ n. 19 GID).

ADVANCED FUNCTIONS
6.1
TOTAL ENERGY COMPENSATION
To use this function it is necessary to install the optional Pitot tube.
Generally a variometer works as follows: it feels the atmospheric pressure change rate considering it as an
altitude change, but, if during the flight the pilot slows the glider (and even more if he does it quickly) there is
a real change of pressure, so a vario ‘without compensation’ records it as a climb, but this variation is caused
by a change of speed (cinetic energy) not a true thermal.
With the total energy compensation, the part of the climb due to the change in velocity is ignored, allowing you
to identify “real” thermals.
To properly set the TOTAL ENERGY
compensation value go to (VARIOMETER
SETUP \ n. 17 TEC), to do it you should fly in
calm air conditions and slow down as if you
are entering a thermal. If the vario shows a
change in lift, you have to increase the total
energy compensation value, until the
change in velocity isn’t recorded as lift.
A typical value for hang gliders is 65. The default setting of “0” deactivates the total energy compensation
function
6.2
POLAR (WITH OPTIONAL PITOT TUBE)
A polar curve (shown in bold on the figure) is the graph of
your glider’s sink rate over its speed range.
The black bold curved line represents the polar. The
glider’s stall speed is shown at point S on the left and the
glider’s max speed at point T on the right of the graph.
On the graph, you can also see three pairs of relative
speed readings and sink rates. The graph shows at point A,
the lowest sink rate achieved at the top of the curve.
Therefore SinkA is the minimum sink rate and VA is the speed at which this is achieved.
