Caution
•
Always operate the instrument in room temperatures listed in
the Environmental Conditions section. Allow sufficient air
circulation by leaving at least 15 cm (6 inches) of clearance
around the instrument.
•
DO NOT overfill the bath. Overflowing liquid may damage the
electrical system. Be sure to allow for thermal expansion of
the fluid as the bath temperature increases. See the Bath
Preparation and Filling section, for specific instructions.
•
Read the Bath Use section, before placing the bath into
service.
•
DO NOT change the values of the bath calibration constants
from the factory set values. The correct setting of these
parameters is important to the safety and proper operation of
the unit.
•
Only authorized personnel should perform the Factory Reset
Sequence if no other action is successful in correcting a
malfunction. You must have a copy of the most recent Report
of Test to restore the test parameters.
•
DO NOT operate this instrument in an excessively wet, oily,
dusty, or dirty environment.
•
The bath is a precision instrument. Although it has been
designed for optimum durability and trouble free operation, it
must be handled with care. Position the bath before the tank is
filled with salt.
•
Most probes have handle temperature limits. Be sure that the
probe handle temperature limit is not exceeded in the air
above the instrument.
•
The instrument and any thermometer probes used with it are
sensitive instruments that can be easily damaged. Always
handle these devices with care. Do not allow them to be
dropped, struck, stressed, or overheated.
•
DO ensure the salt is cleaned from the probes prior to
immersing the probe in the next bath. Clean your probe
between each bath to avoid contamination between bath
fluids.
•
Under filling the bath may reduce the bath performance and
may possibly damage the bath.
•
When calibrating PRTs always follow correct calibration
procedure and calibrate from high temperatures to low
temperatures with the appropriate triple point of water checks.
Never immerse a wet or cold PRT into a bath filled with hot
fluid. Severe damage to the PRT may result as well as personal
injury to the calibration technician.
