HOW THE ALTIMETER WORKS. The Avocet Vertech II
measures altitude by detecting differences in air pressure and
displayingthisinformationasaltitudeabovesealevel.TheVertech
works the same way an aircraft altimeter does.
EFFECTS OF ATMOSPHERIC PRESSURE CHANGES.
Achangeinatmosphericpressurewillmakethedisplayedaltitude
differentfromthe knownaltitudeof alandmark.TheVertech can
be adjusted so that it displays the same altitude as the landmark.
Minor atmospheric pressure changes may cause the displayed
altitudetovaryfromtheactualaltitudeby50feet.Withthearrival
ordepartureofaweatherfront,displayedaltitudecanchange100
to200feet,andastormcancauseachangeofmorethan200feet.
Wind, rain, snow, and humidity do not affect altimeter readings.
Atmospheric pressure changes during a day's activity can affect
the accumulated vertical feet very little–usually less than 1%.
DISPLAY UPDATES. The Vertech disregards small vertical
irregularities, and accumulation of vertical feet does not begin
untiltherehasbeen a 30 foot changeinaltitude.Altitude,vertical
feet,andratedisplaysupdatefrequentlyiftherehasbeenachange
in altitude or a button has been pressed recently. During periods
of inactivity, updates are less frequent.
ADJUSTING BAROMETER OFFSET. Barometer offset
(the relation between altitude and sea level barometer) is set at
thefactory.Toensure barometer accuracy you can checkitafter
ayearortwoandcorrectminordriftifnecessary.Toadjustoffset
firstsetthecorrectaltitudeinthebarometeradjustdisplay.Then
call a local airport to get the current sea level barometer. If the
reported and displayed barometers agree, no adjustment is
necessary.Ifthereisadiscrepancy,notewhetheryourbarometer
reads high or low and by how much. Press and hold the Adjust
Button for 10 seconds. The upper digits blink. Adjust them up if
your barometer reads low or down if it reads high. Adjust with
the Option Button by the amount of the discrepancy previously
noted. If necessary, you can adjust thermometer offset by press-
ingtheFunctionButton.Pressthe AdjustButtontoexit.Nowset
the correct altitude again in the barometer adjust display.
