CHAPTER 3 ALTIMETER MODE
The Altimeter mode 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 mode:
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 (Fig. 1):
• 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 41 OF THIS MANUAL.
