more than 10 days, the instrument needs to be energized for a "dry-out"
period of 2 hours before it can be assumed to meet all of the safety re-
quirements of the IEC 1010-1. If the product is wet or has been in a wet
environment, take necessary measures to remove moisture prior to apply-
ing power such as storage in a low humidity temperature chamber operat-
ing at 50°C for 4 hours or more.
•Overhead clearance is required. Do not place the instrument under a cabi-
net or other structure. Always leave enough clearance to allow for safe
and easy insertion and removal of probes.
•The instrument is intended for indoor use only.
•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 by rolling it into
place. DO NOT attempt to lift the bath. DO NOT move a bath filled
with fluid.
BURN HAZARD
•Extremely cold temperatures may be present in this equipment. Freezer
burns and frostbite may result if personnel fail to observe safety precau-
tions.
•High temperatures may be present in this equipment. Fires and severe
burns may result if personnel fail to observe safety precautions.
ELECTRICAL HAZARD
•These guidelines must be followed to ensure that the safety mechanisms
in this instrument will operate properly. This instrument must be plugged
into a 230V AC electric outlet of the appropriate frequency. The power
cord of the instrument is equipped with a three-pronged grounding plug
for your protection against electrical shock hazards. It must be plugged
directly into a properly grounded three-prong receptacle. The receptacle
must be installed in accordance with local codes and ordinances. Consult
a qualified electrician. DO NOT use an extension cord or adapter plug.
•DO use a ground fault interrupt device. This instrument contains a fluid.
A ground fault device is advised in case fluid is present in the electrical
system and could cause an electrical shock.
•Always replace the power cord with an approved cord of the correct rat-
ing and type. If you have questions, contact a Fluke Fluke Calibration Au-
thorized Service Center (see Section 1.3).
•High voltage is used in the operation of this equipment. Severe injury or
death may result if personnel fail to observe the safety precautions. Before
working inside the equipment, turn off the power and disconnect the
power cord.

Before You Start

BATH FLUIDS
•Fluids used in this bath may produce noxious or toxic fumes under certain
circumstances. Consult the fluid manufacturer’s MSDS (Material Safety
Data Sheet). Proper ventilation and safety precautions must be observed.
•The instrument is equipped with a soft cutout (user settable firmware) and
a hard cutout (set at the factory). Check the flash point, boiling point, or
other fluid characteristic applicable to the circumstances of the bath oper-
ation. Ensure that the soft cutout is adjusted to the fluid characteristics of
the application. As a guideline, the soft cutout should be set 10°C to 15°C
below the flash point of the bath fluid. See Section 8.1, Heat Transfer
Fluid, for specific information on bath fluids and Section 9.8, Cutout.
1.2.2 Cautions
To avoid possible damage to the instrument, follow these guidelines.
•Always operate this instrument at room temperature between 41°F and
122°F (5°C to 50°C). Allow sufficient air circulation by leaving at least 6
inches (15 cm) of clearance around the instrument.
•When filling the tank, ensure the immersion coils are completely covered.
•DO NOT overfill the bath. Overflowing fluid may damage the electrical
system. See Section 5.3, Bath Preparation and Filling, for specific instruc-
tions.
•Read Section 6, Bath Use, before placing the bath into service.
•DO NOT turn the bath on without fluid in the tank and the heating coils
fully immersed.
•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 bath.
•The refrigeration may be damaged or the lifetime shortened if the
set-point temperature is set above 60°C for more than one hour with the
refrigeration manually on. Ensure that the refrigeration is off when the
bath is used above 60°C.
•The Factory Reset Sequence should be performed only by authorized
personnel 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 pa-
rameters.
•DO NOT operate this instrument in an excessively wet, oily, dusty, or
dirty environment.
•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.

COLD BATHS
•Refrigerated baths require that the condensing coil be cleaned periodi-
cally. Accumulation of dust and dirt on the condenser will result in pre-
mature failure of the compressor.
•This bath has been equipped with a brownout and over voltage protection
device as a safety feature to protect the system components.
•Mode of Operation: This bath needs to be plugged into the line voltage
for at least 2 minutes before operation. This is only necessary for the first
time the bath is energized or when it is moved from one location to an-
other. Turning the bath ON or OFF does not trigger the delay.
•If a High/Low voltage condition exists for longer than 5 seconds, the bath
de-energizes. An amber indicator on the back panel lights when this con-
dition exists.
•Re-energization is automatic upon correction of the fault condition and af-
ter a delay cycle of about 2 minutes. If a fault condition exists upon appli-
cation of power, the bath will not energize.
•Under and Over Voltage Protection at 230 VAC
♦Voltage Cutout: ±12.5% (203 - 257 VAC)
♦Voltage Cut In: ±7.5% (213 - 247 VAC)

4 Quick Start
This chapter gives a brief summary of the steps required to set up and operate
the 7009 bath. This should be used as a general overview and reference and not
as a substitute for the remainder of the manual. Please read Section 8 carefully
before operating the bath.
4.1 Set Up
Set up of the bath requires careful unpacking and placement of the bath, filling
the bath with fluid, installing the probe and connecting power. Consult Chapter
4 for detailed instructions for proper installation of the bath. Be sure to place
the bath in a safe, clean and level location.
Fill the bath tank with an appropriate liquid. For operation at moderate bath
temperatures, clean distilled water works well. Carefully pour the fluid into the
bath tank through the large rectangular access hole above the tank avoiding
spilling any fluid. The fluid must not exceed a height of 1/2 inch below the bath
lid.
The control probe must be inserted through the lid into the bath and plugged
into the socket at the back of the bath.
4.2 Power
Plug the bath power cord into a mains outlet of the proper voltage, frequency,
and current capability. See Section 3.1, Specifications for power details. Set the
“HEATER” switch on the front panel to position “LOW” and turn the bath on
using the front panel “POWER” switch. The bath will turn on and begin to heat
or cool to reach the previously programmed temperature setpoint. The front
panel LED display will indicate the actual bath temperature.
4.3 Setting the Temperature
In the following discussion a solid box around the word SET, UP, EXIT or
DOWN indicates the panel button while the dotted box indicates the display
reading. Explanation of the button or display reading are to the right of each
button or display value.
To view or set the bath temperature set-point proceed as follows. The front
panel LED display normally shows the actual bath temperature.
24.68 C Bath temperature display
When “SET” is pressed the display will show the set-point memory that is cur-
rently being used and its value. Eight set-point memories are available.

Press “EXIT” and the bath temperature will be displayed again.
Return to the temperature display
24.73 C Bath temperature display
The bath will heat or cool until it reaches the new set-point temperature. Set the
heater switch to position “HIGH” to allow the bath to more quickly reach a
higher temperature. The “HIGH” setting may be necessary to reach higher tem-
peratures and control at high temperatures.
When setting the set-point temperature be careful not to exceed the temperature
limit of the bath fluid. The over-temperature cutout should be correctly set to
prevent this from happening. See Section 8.8.
If operating the bath below 45 °C set the COOLING power switch to ON. The
cooling temperature may require adjustment to provide the proper amount of
cooling. See section 8.5.
To obtain optimum control stability adjust the proportional band as discussed in
Section 9.7.

5 Installation
5.1 Unpacking
Unpack the bath carefully and inspect it for any damage that may have oc-
curred during shipment. If there is shipping damage, notify the carrier
immediately.
Verify that all components are present:
•The 7009 Bath
•Access Hole Cover
•Controller Probe
•User’s Guide
•Drain Elbow
•Report of Test
If you are missing any item, please contact a Fluke Calibration Authorized Ser-
vice Center (see Section 1.3).
5.2 Bath Environment
The 7009 Bath is a precision instrument which should be located in an appro-
priate environment. The location should be free of drafts, extreme temperatures
and temperature changes, dirt, etc. The surface where the bath is placed must
be level.
If used at higher temperatures where fluid vaporization is significant, use of a
fume hood is recommended.
5.3 Bath Preparation and Filling
The 7009 bath is designed for use with standard resistors, therefore, the soft
cutout of the instrument has been set at the factory to 50°C to protect standard
resistors placed in the bath. In order to use the bath for other calibration pur-
poses, the user should insure that the soft cutout is adjusted appropriately for
the application.
The 7009 Bath is not provided with a fluid. Various fluids are available from
Fluke Calibration and other sources. Depending on the desired temperature
range, any of the following fluids, as well as others, may be used in the bath:
•Water
•Ethylene Glycol/Water
•Methanol
•Mineral oil
13
Installation

•Silicone oil
Fluids are discussed in detail in Section 8.1.
Remove any access hole cover from the bath and check the tank for foreign
matter (dirt, remnant packing material, etc.). Use clean unpolluted fluid. Care-
fully fill the bath through the large square access hole to a level that will allow
for stirring and thermal expansion. The fluid should never exceed a height of
1/2" below the top of the tank. Carefully monitor the bath fluid level as the bath
temperature rises to prevent overflow or splashing. Remove excess fluid if nec-
essary and with caution if the fluid is hot.
Be careful to prevent bath fluid from spilling on the stirring motor while filling.
Note that underfilling may reduce bath performance and may possibly damage
the bath heater.
5.4 Probe
Inspect the bath controller probe. It should not be bent or damaged in any way.
Reasonable caution should be used in handling this probe as it contains a preci-
sion platinum sensor and is mechanically shock sensitive. Dropping, striking,
or other physical shock may cause a shift in resistance in the probe resulting in
diminished bath accuracy. If damaged, the probe can be replaced. Contact a
Fluke Calibration Authorized Service Center for assistance.
Insert the probe into the 1/4 inch probe hole at the top left side of the bath lid.
The tip of the probe must be well immersed in the fluid. The probe connector is
plugged into the rear of the bath into the socket labelled “PROBE”.
5.5 Power
With the bath power switch off, plug the bath into an AC mains outlet of the
appropriate voltage, frequency, and current capacity. See Section 3.1, Specifica-
tions for power details.
Be sure the stirring motor power cord is plugged into the “STIRRER” socket at
the back of the bath.
