THE FALCON is a quick, convenient and
inexpensive way to accurately measure
pressure in almost any environment.
Under 4 inches in diameter, the
Falcon will fit in your hand and, yet,
hold most standard quick-connects
and fittings. The custom-made
aluminum case is water-resistant and
has an advanced shock-absorbing
system that is designed to take more
abuse than the typical electronic
deadweight, before being damaged.
Have you ever used a electronic
pressure gauge when the temperature
is changing rapidly? Most gauges will
have extremely poor accuracies unless
the temperature is stable. To prevent
this we calibrate the Falcon from
-40°C to +60°C, and use advanced
digital compensation technology, unlike
almost all other pressure gauges.
As a result, you don’t have to worry
about the outside temperature
changes affecting the
displayed pressure. For example,
on the graph below, you can see
data from a typical Falcon with a
range of 3500 psi, tested at 1000 psi
of pressure. The temperature was then
ramped from –20°C to +20°C in 1
hour, and then back down. There is 0.5
psi (0.015% Full Scale) deviation from
the correct value, well below the stated
accuracy of +/- 0.04% Full Scale.
Software features such as one touch
memory, peek pressure detect, and
manual zero makes the Falcon
convenient to operate. Included with
every deadweight is a watertight
carrying case to keep your Falcon
safe when its not being used and, it
even has enough room to house most
pressure connections too. In short, we
built this electronic deadweight to satisfy
the needs of the field operator for
ruggedness, and unparalleled accuracy
for the instrumentation technician.

Falcon
Electronic Deadweight
User’s Manual 1v06
Copyright 2002 Cal-Scan Services Ltd.
Overview
The Falcon Electronic Deadweight is a quick and inexpensive way to measure static pressure.
Since it’s calibrated from -40 °C to +60 °C you don’t have to worry about the outside temperature
changes affecting the pressure, unlike most other electronic deadweights.
The custom-made aluminum case and advanced shock-absorbing system are designed to take more
abuse before being damaged than the typical deadweight. Included is an impact-resistant, water-resistant
case that is big enough to hold most standard quick connects and fitting’s while still being attached to
the Falcon.
In short, we have built this deadweight to satisfy the needs of the field operator for toughness, reliability
and unparalleled accuracy.

If you damage the deadweight by stripping the threads or by rotating the
case to remove a fitting without a wrench, you will void your warranty !!!
Bad Good
Using Quick Connects and Valves
Using a quick connect is okay as long as it does not seal fluid in the connection. If the quick connect
seals the fluid, drill it out so the pressure has somewhere to bleed, otherwise changes in temperature can
put thousands of pounds of pressure on the transducer, possibly overpressuring it. This can also happen
when using valves that seal fluid against the sensor.
Installation
The Falcon Electronic Deadweight ships with a 1/4” NPT to 1/2” NPT adapter that allows you to easily
hook up to almost any adapter or quick connect. There are just a few points to remember.
Installing Fittings
The Falcon is designed to be robust but, if you do not use a wrench to attach any fitting or install the
deadweight on a pressure source, you could damage it.
Operating the Falcon
To turn on the Falcon Deadweight, press either the Cor Mkey. The unit will turn off automatically
depending on what the Sleep-Mode is set to, see below. There are three main modes the Falcon can be
in: Sampling, Memory and Setup. These modes are reached by repeatedly pressing theCkey.
Sampling: The Falcon Electronic Deadweight samples every 3 seconds. When the gauge is sam-
pling, busy will come up on the display, and the gauge won’t respond to key presses until it’s finished
sampling.
In gauge mode (psig or kPag), it is possible to zero the deadweight to atmospheric pressure. While the
Falcon is sampling, press both theMand the9key to zero the pressure. Note that this has no effect
in absolute mode. You can reset the zero offset back to the factory zero which will be explained below.
The Falcon can either save the current pressure for later viewing by pressing theMbutton, or if Peak-
Detect has been activated, the highest pressure recorded will be saved automatically. If the Peak-Detect
is on pressing theMbutton will clear the peak value so a new lower peak will be recorded.
Trapping fluid against the pressure sensor and exposing it to a change in
temperature can damage the sensor and void your warranty !!!
If you use a quick connect on the gauge ensure the stem on the Falcon has
no check valve, a SESO type !!!

Memory: After pressing theCbutton a second time, the Falcon will show the last saved value or if
the PeakMin-Detect is on, the peak and minimum pressure. In this case the two values will be shown by
alternating the display every 3 seconds (The lower value is the minimum and the higher the peek pressure).
Setup: Pressing theCbutton a third time will allow you to change the settings of the Falcon.
Changing the Engineering Units: kPaa, kPag, psia, psig
Press theCbutton until Setup is displayed.
Press theMbutton to display Units, and the current unit will be displayed.
Press the9button, and the units will toggle between psia, psig, kPa and kPag.
Press theMbutton to save the desired unit.
Reset the Zero Offset: This useful if the Falcon has been accidentally zeroed under pressure, or
if you want to see how much the deadweight has shifted from the factory zero.
Press the Cbutton until Setup is displayed.
Press the Mbutton to display Units.
Press the Cbutton to display Reset.
Press the Mbutton to reset the gauge back to factory zero.
PeakMin-Detect: This feature changes how the memory mode works. If the PeakMin-Detect is
ON, the deadweight will display the last peak and minimum pressure sampled (instead of showing
the last saved pressure). When memory is displayed the peak and minimum pressure will be shown,
alternating every 3 seconds. By pressing the Mkey when the deadweight is in sampling mode,
and it will clear the peak and minimum pressure, so new pressures can be recorded.
Press the Cbutton until Setup is displayed.
Press the Mbutton to display Units.
Press the Cbutton to display Reset.
Press the Cbutton to display Pon or Poff.
Press the 9key to toggle between Pon or Poff.
Sleep-Mode: Changes how the Falcon automatically turns off. Normally, the sleep-mode is set to
toff. In toff, the deadweight will stay on as long as there is more than 2 pounds of pressure. As
soon as there is less than 2 pounds of pressure, it will shut off after 5 minutes of inactivity. If the
Falcon has been set to ton, it will shut off in 5 minutes, after you stop pressing any of the buttons.
Press the Cbutton until Setup is displayed.
Press the Mbutton to display Units.
Press the Cbutton 3 times, until toff appears.
Press the 9key to toggle between toff and ton modes.
Press the Mkey to save the desired mode.
