• The furnace generates extreme temperatures. Precautions must be taken to
prevent personal injury or damage to objects. Probes may be extremely
hot when removed from the furnace. Cautiously handle probes to prevent
personal injury. Carefully place probes on a heat resistant surface or rack
until they are at room temperature. SPRT's should be placed in an anneal-
ing furnace if removed at temperatures greater than 500°C.
• Use only grounded AC mains supply of the appropriate voltage to power
the instrument. See Section 2.1, Specifications, for power requirements.
• The 9116A Furnace utilizes high voltages and currents to create high tem-
peratures. Caution should always be maintained during installation and
use of this instrument to prevent electrical shock and burns. Fire can be a
hazard for any device that produces high temperatures. Proper care and
installation must be maintained. Responsible use of this instrument will
result in safe operation.
• Calibration Equipment should only be used by Trained Personnel.

CAUTIONS

To avoid possible damage to the instrument, follow these guidelines.
• Components and heater lifetimes can be shortened by continuous high
temperature operation.
• Operate the instrument in room temperatures as indicated in Section 2.2,
Environmental Conditions. Allow sufficient air circulation by leaving at
least 6 inches of space between the furnace and nearby objects. Nothing
should be placed over the top of the furnace. The furnace should not be
placed under cabinets or tables. Extreme temperatures can be generated
out the top of the well. The furnace is equipped with cooling coils, use
cold water circulation when the furnace is used above 600°C. (For specif-
ics see Section 4.5 Plumbing.)
• The furnace is a precise instrument. Although it has been designed for op-
timum durability and trouble free operation, it must be handled with care.
The instrument should not be operated in wet, oily, dusty or dirty environ-
ments. Keep the well of the instrument free of any foreign matter. Do not
operate near flammable materials.
• Do not use fluids to clean out the well.
• If a main supply power fluctuation occurs, immediately turn off the fur-
nace. Power bumps from brown-outs and black-outs can damage the in-
strument. Wait until the power has stabilized before re-energizing the
furnace.
• The unit is not equipped with wheels. It is considered to be permanently
set once it has been installed. If the unit must be moved for some reason,
be sure that the fixed point cell has been removed before moving the fur-
nace. Any movement of the furnace with the cell inside can damage the
cell. The unit is not designed to be lifted or carried. If it must be picked
up, it is advisable that two people pick the unit up by placing their hands
