Calscan Falcon - Installation

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
C
or
M
key. 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 the
C
key.
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 the
M
and the
9
key 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 the
M
button, or if Peak-
Detect has been activated, the highest pressure recorded will be saved automatically. If the Peak-Detect
is on pressing the
M
button 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 !!!
