Installation
Environmental Conditions
The 6100 Calorimeter is completely assembled and
given a thorough test before it is shipped from the
factory. If the user follows these instructions, instal-
lation of the calorimeter should be completed with
little or no difficulty. If the factory settings are not
disturbed, only minor adjustments will be needed to
adapt the calorimeter to operating conditions in the
user’s laboratory.
This apparatus is to be used indoors. It requires at
least 4 square feet of workspace on a sturdy bench or
table in a well-ventilated area with convenient access
to an electric outlet, running water and a drain.
Required Consumables, Utilities and Power
Requirements
The 6100 Calorimeter System requires availability of
Oxygen, 99.5% purity, 2500 psig maximum.
The power requirements for the subassemblies of the
6100 Calorimeter are:
Calorimeter
115VAC, 2.0 Amps. 50/60 Hz
230VAC, 2.0 Amps, 50/60 Hz
Printer
100 to 240 VAC, 0.35 Amps 50/60 Hz
Plug the power line into any grounded outlet provid-
ing proper voltage that matches the specification on
the nameplate of the calorimeter. The calorimeter will
draw approximately 100 watts of power. 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 instrument
boot sequence. When the boot sequence is complete,
the calorimeter Main Menu is displayed.
Oxygen Filling Connection
The 6100 Calorimeter is equipped with an automatic
bomb oxygen filling system. This system consists of
an oxygen pressure regulator with a relief valve that
mounts on an oxygen tank and a controlled solenoid
inside the calorimeter. To install the regulator on the
oxygen supply tank, unscrew the protecting cap from
the oxygen tank and inspect the threads on the tank
outlet to be sure they are clean and in good condi-
tion. Place the ball end of the regulator in the outlet
and draw up the union nut tightly, keeping the gages
tilted slightly back from an upright position. Connect
the regulator to the oxygen inlet fitting on the back of
the calorimeter case. This hose should be routed so
that it will not kink or come in contact with any hot
surface. Connect the high-pressure nylon hose with
the push on connector to the oxygen bomb outlet
connection on the back of the calorimeter.
All connections should be checked for leaks. Any
leaks detected must be corrected before proceeding.
Instructions for operating the filling connection are in
the Operating Instructions chapter. Adjust the pres-
sure regulator to deliver 450 psi of O
2
. Assemble the
oxygen bomb without a charge and attach the filling
hose to the bomb inlet valve. Press the O
2
Fill key
on the Calorimeter Operation page and observe the
delivery pressure on the 0 – 600 psi gage while the
oxygen is flowing into the bomb. Adjust the regula-
tor, if needed, to bring the pressure to 450 psi. If there
is any doubt about the setting, release the gas from
the bomb and run a second check.
Printer and Balance Connections
Connect the printer to the calorimeter at this time.
The Parr 1758 Printer is configured and furnished with
a cord to connect directly to the USB port on the back
of the calorimeter.
The balance port connection, if needed, should be
made at this time. If both a printer and a balance will
be used then a USB hub will need to be installed.
Contact Parr to determine the correct cable to connect
the balance to the calorimeter.
Standardizing the Calorimeter
The calorimeter must be accurately standardized
prior to actually performing calorimetric tests on
sample materials. Review Appendix C - Standardiza-
tion, in order to become familiar with the general
