Limited Warranty & Limitation of Liability
Each product from Fluke Corporation (“Fluke”) is warranted to be free from defects in material and
workmanship under normal use and service. The warranty period is one year for the Calibration Bath.
The warranty period begins on the date of the shipment. Parts, product repairs, and services are warranted
for 90 days. The warranty extends only to the original buyer or end-user customer of a Fluke authorized
reseller, and does not apply to fuses, disposable batteries or to any other product, which in Fluke’s opin-
ion, has been misused, altered, neglected, or damaged by accident or abnormal conditions of operation or
handling. Fluke warrants that software will operate substantially in accordance with its functional speci-
fications for 90 days and that it has been properly recorded on non-defective media. Fluke does not war-
rant that software will be error free or operate without interruption. Fluke does not warrant calibrations
on the Calibration Bath.
Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers
only but have no authority to extend a greater or different warranty on behalf of Fluke. Warranty support
is available if product is purchased through a Fluke authorized sales outlet or Buyer has paid the applica-
ble international price. Fluke reserves the right to invoice Buyer for importation costs of repairs/replace-
ment parts when product purchased in one country is submitted for repair in another country.
Fluke’s warranty obligation is limited, at Fluke’s option, to refund of the purchase price, free of charge
repair, or replacement of a defective product which is returned to a Fluke authorized service center within
the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center or send the product, with
a description of the difficulty, postage, and insurance prepaid (FOB Destination), to the nearest Fluke au-
thorized service center. Fluke assumes no risk for damage in transit. Following warranty repair, the prod-
uct will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that the
failure was caused by misuse, alteration, accident or abnormal condition or operation or handling, Fluke
will provide an estimate or repair costs and obtain authorization before commencing the work. Following
repair, the product will be returned to the Buyer transportation prepaid and the Buyer will be billed for
the repair and return transportation charges (FOB Shipping Point).
THIS WARRANTY IS BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL
OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IM-
PLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
Fluke SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL. OR CONSE-
QUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF DATA, WHETHER ARISING FROM
BREACH OF WARRANTY OR BASED ON CONTRACT, TORT, RELIANCE OR ANY OTHER
THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or
limitation of incidental or consequential damages, the limitations and exclusions of this warranty may not
apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court of com-
petent jurisdiction, such holding will not affect the validity or enforceability of any other provision.

1.2 Safety Information
Use this instrument only as specified in this manual. Otherwise, the protection
provided by the instrument may be impaired.
The following definitions apply to the terms “Warning” and “Caution”.
•“Warning” identifies conditions and actions that may pose hazards to the
user.
•“Caution” identifies conditions and actions that may damage the instru-
ment being used.
1.2.1 Warnings
To avoid personal injury, follow these guidelines.
GENERAL
•DO NOT use the instrument for any application other than calibration
work. The instrument was designed for temperature calibration. Any other
use of the instrument may cause unknown hazards to the user.
•DO NOT use the instrument in environments other than those listed in
the user’s guide.
•DO NOT overfill the bath. Overflowing extremely cold or hot fluid may
be harmful to the operator. See Section 5.3, Bath Preparation and Filling,
for specific instructions.
•Follow all safety guidelines listed in the user’s manual.
•Calibration Equipment should only be used by Trained Personnel.
•If this equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
•Before initial use, or after transport, or after storage in humid or semi-hu-
mid environments, or anytime the instrument has not been energized for
User’s Guide

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.
