CHAPTER 4 ALTIMETER MODE
Note: This feature applies to the Altimax, Vector and X-Lander.
The Altimeter function provides the user with:
an adjustable unit of measure either meter or feet: meter range -500 to 9,000; ft range -1,600 to 29,500;
a resolution of 5m or 10ft;
a display up-date on the rate of vertical movement in intervals of 1 second for 3 minutes, then every 10
seconds or less;
an automatic 24-hour memory in one hour intervals showing altitude and vertical ascent/descent rate;
and
a logbook, recording approximately 3800 sets of data
(one set = altitude, vertical ascent/descent rate and time).
To view and use the Altimeter function:
Check the Mode Indicator Bar. If the mode arrow is not on ALTI, PRESS the [Mode] button until the arrow
is directly below ALTI on the bar.
In the ALTIMETER mode:
Field 1 displays the vertical ascent or descent rate;
Field 2 displays the current altitude in increments of 5 meters or 10 feet (depending on the unit of
measure selected); and
Field 3 displays the current time.
The Outer Circumference graphically displays the altitude in hundreds of meters or feet over a full
thousand where one complete circle is equivalent to 1000.
IMPORTANT NOTE: IN ORDER TO SET THE ALTITUDE IN THE ALTIMETER MODE, THE ALTITUDE MUST BE
KNOWN. THAT INFORMATION CAN BE FOUND BY UTILIZING A TOPOGRAPHICAL MAP, IDENTIFYING THE
CURRENT LOCATION WITH THE ASSOCIATED ALTITUDE MARKED. THE USER CAN PROCEED AND FOLLOW
THE INSTRUCTIONS, SETTING THE ALTIMETER, PROVIDED IN THE SECTION BELOW.
DETAILS REGARDING THE EFFECT OF AIR TEMPERATURE ON ALTITUDE MEASUREMENT ARE SHOWN ON
PAGE 48 OF THIS MANUAL.
