• 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 Section 5.3, Bath Preparation and Filling, for
specific instructions.
• Read Section 6, Bath Use, before placing the unit into service.
• DO NOT change the values of the bath calibration constants from the fac-
tory 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 op-
timum durability and trouble free operation, it must be handled with care.
Position the bath before the tank is filled with fluid.
• 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 in-
struments 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 fluid is cleaned from the probes prior to immersing the
probe in the next bath. Clean your probe between each bath to avoid con-
tamination 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 per-
sonal injury to the calibration technician.
• This bath is not designed to be portable. Therefore, moving the bath once
it has been installed should be kept to a minimum. NEVER MOVE A
BATH THAT IS FULL OF "HOT" FLUID. This action could be ex-
tremely dangerous and could result in personal injury to the person mov-
ing the bath. If the bath is going to be placed in an area where it may need
to be moved frequently, Hart Scientific sells a special cart designed to ac-
commodate the bath. However, even with a cart the bath should not be
moved full of "hot" fluid. The fluid can splash causing injury or if the
bath and cart tip, the "hot" fluid could cause damage to the surrounding
area and personnel.
• If the bath must be moved, be sure to drain the fluid to prevent any injury.
To safely move the bath, two people are required. One person should lift
