3.0 GENERAL INFORMATION
3.01 Precision Baths are widely used in research
and quality control. Their superb temperature
uniformity and stability makes them especially
desirable for legal or reference tests.
CAUTION
DO NOT APPLY POWER TO THE WATER BATH
BEFORE FILLING THE WATER BATH PAN WITH
THE RECOMENDED WATER SOLUTION (SEE
SECTION 7.02). OPERATING THE BATH
WITHOUT A WATER SOLUTION COULD RESULT
IN OVERHEATING AND DAMAGE TOT HE
HEATER.
3.02 The microprocessor control panel houses all
functions necessary to operate the bath.
The push-button keys and single display
window allows the operator to adjust bath
temperature and temperature calibration via
a single set of controls.
3.03 The Proportional Integral Derivative (PID)
temperature control allows precise
temperature control. Use of the gable cover
provided is required to maintain optimal
temperature sensitivity.
3.04 A high limit temperature cutout is provided in
the event of an empty water bath. If the sensor
reads a temperature 5°C higher than the set
temperature, a high temperature cutout will
occur indicated by a display reading of "EEE,"
and the heater will be inhibited from operating.
To reset the bath, the power must be turned
off and then back on again. The high limit
temperature cutout is internally set for 5°C
above any set temperature and can not be set
by the user.
3.05 The interior of the bath is constructed of
stainless steel and is designed for operation
with distilled water or water solutions, such
as water ethylene glycol with corrosion
inhibitor's added. The body is made from
galvanized steel and is painted for added
protection. A gable cover is also provided
with the bath.
3.06 The 240-volt units are identical in appearance
to the 120-volt units.
NOTE:
USING CHLORINATED TAP WATER OR ADDITIVES
THAT CONTAIN CHLORINE WILL VOID THE
MANUFACTURER'S WARRANTY. SIMILARLY, HIGH
PURITY (DEIONIZED) WATER THAT DOES NOT FALL
WITHIN THE RESISTIVITY RANGE OF 50K TO 1M
OHM AND THE PH RANGE FROM 7 TO 9 WILL VOID
THE WARRANTY. CONTACT TECHNICAL SERVICES
WITH ANY QUESTIONS.
