Hooking up the instrument
When you first get your instrument you might be a bit confused about
how
to hook things up. There will be laminated sheet that will tell
you some quick instructions for the safe use of the instrument.
In
addition you will find a book called "Guidelines for Measuring Plant
Moisture
Stress with a Pressure Chamber". This will be a wealth of
knowledge
for the beginner.
If you have a Model 600,
603, 670,
1000 or 1003 you will need to hook up
the instrument to the Portable Tank or other
nitrogen source.
If you have a Model 610, it has
a
internal tank and does not require any attachment to the tank.
You
just need to fill the tank with nitrogen
and you will be ready to make measurements.
If you have a Model 615, the tank should
be already attached to the instrument as it is a self-contained
unit. You will need to fill the tank with nitrogen and you will
be ready to make measurements.
To hook up and operate any of the other pressure chambers you must
have
the following 3 items:
1) Pressure Chamber Instrument
2) Portable Tank or Nurse Tank
3) 6 foot filling hose

Pull gently on hose to ensure properly connected
Your system should now look like this
You are now ready to make measurements
