Safety Information
To avoid electrical shock, always:
1. Use a properly grounded electrical outlet of
correct voltage and current handling capability.
2. Ensure that the equipment is connected to
electrical service according to local national
electrical codes. Failure to properly connect may
create a fi re or shock hazard.
3. For continued protection against possible
hazard, replace fuses with same type and rating
of fuse.
4. Disconnect from the power supply before
maintenance or servicing.
To avoid personal injury:
1. Do not use in the presence of fl ammable or
combustible materials; fi re or explosion may
result. This device contains components which
may ignite such material.
2. Refer servicing to qualifi ed personnel.
Intended Usage
If the instrument is used in a manner not specifi ed
by Parr Instrument Company, the protection provid-
ed by the equipment may be impaired.
General Specifi cations
Electrical Ratings
115VAC, 1.0 Amp, 50/60 Hz
230VAC, 1.0 Amp, 50/60 Hz
Before connecting the calorimeter to an electrical
outlet the user must be certain that the electrical
outlet has an earth ground connection and that the
line, load and other characteristics of the installation
do not exceed the following limits:
Voltage: Fluctuations in the line voltage should not
exceed 10% of the rated nominal voltage shown on
the data plate.
Frequency: Calorimeters can be operated from ei-
ther a 50 or 60 Hertz power supply without affecting
their operation or calibration.
Current: The total current drawn should not exceed
the rating shown on the data plate on the calorim-
eter by more than 10 percent.

midity.
Provisions for Lifting and Carrying
Before moving the instrument, disconnect all con-
nections from the rear of the apparatus. Lift the
instrument by grabbing underneath each corner.
Cleaning & Maintenance
Periodic cleaning may be performed on the exterior
surfaces of the instrument with a lightly dampened
cloth containing a mild soap solution. All power
should be disconnected when cleaning the instru-
ment. There are no user serviceable parts inside the
product other than what is specifi cally called out
and discussed in this manual. Advanced trouble-
shooting instructions beyond the scope of this
manual can be obtained by calling Parr Instrument
Company in order to determine which part(s) may
be replaced or serviced.
