SEA LEVEL BAROMETER.
There
are two kinds of barometers; fixed loca-
tion and moving location. Moving ba-
rometers are designed to be used at
varying elevations. The Vertech, like
aircraft altimeters, contains a moving
location barometer. When you set it,
you see both a barometer reading and
an altitude reading. The altitude reading changes whenever there is
a change in elevation or a change in the weather, but the barometer
reading does not move until the user sets it by adjusting the altitude.
SETTING THE SEA LEVEL BAROMETER.
To find your
current Sea Level Barometer, you must know your altitude. Sea
Level Barometer does not change until you set it, and setting it has
no effect on altitude functions. To set, press the Adjust Button in
the Weather Function (C1). Both upper and lower displays blink.
Use the Option Button to adjust the altitude in the lower display
to your present altitude. This updates Sea Level Barometer in the
upper display. A sea level barometer above 29.92 inches is generally
associated with stable weather, and one below 29.92 with unstable
weather. If you don't know your altitude, you can set sea level
barometer from a TV weather report or by phoning a local airport
to get the current barometer reading. In this case, adjust the
barometer until it matches the report. The lower display then
shows your current altitude. Exit by pressing the Adjust Button.
BAROMETRIC TREND.
The lower display shows Barometric
Trend. A plus sign (+) indicates an increasing trend, and a minus (-)
sign a decreasing trend. Altitude change affects the trend, so trend
information is only accurate when read at the altitude of the last
trend reset. To reset the trend to zero, press the Start/Stop button.

Set the Sea Level Barometer by adjusting the altitude in the lower
display to match your current altitude. In this example when the alti-
tude of 380 feet was adjusted to the actual altitude of 320 feet, the
barometer was corrected from 29.92 inches of mercury to 29.86.

STOPWATCH.
Start and stop the
Stopwatch (D1) by pressing the Start /
Stop button. The upper display is called
the Split Timer and the lower display is
the Lap Timer. They will both display the
same time until you create splits that are
partial times for the lap. Splits and laps of
up to 23:59:59 can be recorded. At
23:59:59 the display resets to zero and continues to count. Resolu-
tion is to .05 second to 29:59.95, then in seconds.
SPLIT AND LAP MEMORY.
To reach
Split/Lap Memory (D2) press the Option
Button when the Stopwatch is stopped. The
time of the last split recorded along with the
time of its associated lap will be displayed.
The middle display shows the number of
the split from that particular lap and the
“M” memory icon to indicate that you are
in memory. Press the Option Button to scroll through the recorded
splits and laps. Press the Function Button to return to the Stopwatch.
As you view a group of splits by pressing the Option Button, the Lap Time in
the lower display will be the total of the current and previous splits.
Each time you press the Option Button with the Stopwatch running a new
split is created. Its number is shown in the middle display.

CREATING SPLITS.
Create a group of up to 32 splits by pressing
the Option Button while the Stopwatch is running. Each time you
press the Option Button the display will freeze the last split for
viewing (6 seconds), then time for the new split will count in the
upper display. The lower display will continue to accumulate the total
time (Lap Time) since last reset. If you record more than 32 splits and
laps and fill the memory, you can continue to use the stopwatch, but
no further splits or laps will be saved.

RESETTING INFORMATION IN MEMORY.
To reset all the
splits and laps in memory, hold down the Adjust Button for 5 seconds
while you are in the Split/Lap Memory function (D2). The Vertech will
beep to indicate that everything is reset. You cannot reset times in
memory individually.
CREATING SPLITS BY STARTING AND STOPPING.
Stop-
ping the Stopwatch (D1) puts the time shown in the Split Timer into
memory. If you start again without resetting, you will create a new
split in the upper display, and will keep your lap time. Reset by pressing
the Adjust button.
RESETTING THE LAP.
Reset the Lap Time by pressing the Adjust
Button when the Stopwatch is stopped. The lap and all its splits are
put into memory.
