The type of tubing and the wall thickness also has
an effect on the amount of tightening required.
Plastic tubing requires a minimal amount of ad-
ditional tightening while heavy wall metal tubing
may require somewhat more tightening. In general,
the nut only needs to be tightened about 1/8 turn
beyond finger tight where the ferrule seats in order
to obtain a tight seal.
Over tightening the nut should be avoided. Over
tightening the nut causes distortion (flaring) of the
lip of the tube fitting where the ferrule seats. This
in turn causes the threaded portion of the body to
deform. It becomes difficult to tighten the nut by
hand during a subsequent re-tightening when the
fitting body becomes distorted in this manner.
Required Consumables, Utilities and Power
Requirements
The 6400 Calorimeter requires availability of
oxygen, 99.5% purity, with appropriate connection,
2500 psig, maximum.
The 6400 Calorimeter requires availability of ni-
trogen or air, oil and water free, with appropriate
connection, 2500 psig, maximum.
Approximately 16L of distilled water are required to
fill the external pressurized rinse tank.
Approximately 2L of distilled, de-ionized, or tap
water, with a total hardness of 85 ppm or less, are
required for filling the internal cooling reservoir.
The power requirements for the sub-assemblies of
the 6400 Calorimeter are:
Calorimeter
5.0 Amps @ 120 VAC
3.0 Amps @ 240 VAC
Printer
(100 to 240 VAC, 50/60 Hz) 0.35 Amps
Electrical Connection
Plug the power line into any grounded outlet provid-
ing proper voltage that matches the specification on
the nameplate of the calorimeter. Grounding is very
important not only as a safety measure, but also to
ensure satisfactory controller performance. If there
is any question about the reliability of the ground
connection through the power cord, run a separate
earth ground wire to the controller chassis.
Turn the power switch to the ON position. After
a short time, the Parr logo will appear on the LCD
display followed by a running description of the in-
strument boot sequence. When the boot sequence
is complete, the Main Menu is displayed.
Front Panel Meter
The panel meter on the front of the calorimeter
controls the temperature of the water in the internal
cooling resorvoir. The setpoint is locked at 15 °C.
A red light will flash in the upper left corner of the
display when the water is being cooled.
