How High
TM
Model Aircraft Altimeter
H
ow High? It’s a common question
for anyone who has ever fl own a
model aircraft. Now there is a simple
and inexpensive way to answer that
question with accuracy.
The How High altimeter pro-
vides peak altitude readings
when they are most useful – at
the fi eld, right after a fl ight.
A single light-emitting diode
(LED) reports altitude data
through a series of fl ashes. Simply wav-
ing your fi nger across the LED activates
the altitude report.
The How High unit is complete. It
does not require the use of a computer,
ground-based receiver, or any other
equipment. It needs only a 3.2V to 12V
power source. Plug it into any available
channel on your R/C receiver, or run it
off a separate battery. Smaller than a
postage stamp and lighter than a dime
(2.2g), the How High altimeter easily in-
stalls into almost any fl ying model.
Just like the altimeter in a full-scale air-
craft, the How High altimeter determines
altitude by sensing minuscule changes in
atmospheric air pressure. It uses a state-
of-the-art pressure sensor and propri-
etary calculation and fi ltering techniques
to provide a level of accuracy previously
unavailable in such a low cost, tiny in-
strument.
OPERATION
Understanding how the How High oper-
ates will help you decide where to install
the unit – so, we will cover this topic
fi rst. Full installation instructions are in
the next section.
Using the How High is easy:
1) Turn the unit on
2) Make your fl ight
3) Read the peak altitude
1) Power Up
Before your fl ight, apply power to the
unit. If you have it plugged into your
R/C receiver, this is as simple as turning
on your receiver switch. The LED will
light up for about 3 seconds then turn off
for another 3 seconds. Start your fl ight
at any time. There is no warm-up or cali-
bration delay.
2) Your Flight
As long as power is applied, the LED
will output a quick fl ash about every 2
seconds. This “heartbeat” lets you know
the unit is on and all is well. [Note: If
your unit is plugged into an R/C chan-
nel, and you move that stick or switch on
your transmitter to its limit, the LED will
output 3 quick fl ashes. This is normal
and is not a sign of a problem.]
Throughout the fl ight, the How High is
making high-resolution measurements
of the atmospheric pressure and temper-
ature every second.
