LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship under normal use and
service. The warranty period is one year and begins on the date of shipment. Parts, product repairs, and
services are warranted for 90 days. This 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 product which, in
Fluke's opinion, has been misused, altered, neglected, contaminated, or damaged by accident or abnormal
conditions of operation or handling. Fluke warrants that software will operate substantially in accordance
with its functional specifications for 90 days and that it has been properly recorded on non-defective media.
Fluke does not warrant that software will be error free or operate without interruption.
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 only if product is purchased through a Fluke authorized sales outlet or Buyer has paid the
applicable international price. Fluke reserves the right to invoice Buyer for importation costs of
repair/replacement 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 to obtain return
authorization information, then send the product to that service center, with a description of the difficulty,
postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Following
warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke
determines that failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal
condition of operation or handling, including overvoltage failures caused by use outside the product’s
specified rating, or normal wear and tear of mechanical components, Fluke will provide an estimate of 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 IMPLIED WARRANTY
OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE
FOR ANY SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OR LOSSES,
INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR 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 or other
decision-maker of competent 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
instrument being used.
1.2.1 Warnings
Warnings
To avoid personal injury, follow these guidelines.
•BURN HAZARD - DO NOT touch the well access surface of
the unit.
•The temperature of the well access is the same as the
actual temperature shown on the display. If the unit is set
at 600°C and the display reads 600°C, the well is at 600°C.
•The top sheet metal of the furnace may exhibit extreme
temperatures for areas close to the well access.
•The air over the well can reach temperatures greater than
200°C. Probes should only be inserted and removed from
the unit when the unit is set at temperatures less than
200°C.
•DO NOT turn off the unit at temperatures higher than
100°C. This could create a hazardous situation. Select a
set-point less than 100°C and allow the unit to cool before
turning it off.
•DO NOT remove inserts and insulators at high
temperatures. Inserts and insulators are the same
temperature as the display temperature.
•DO NOT operate this unit without a properly grounded,
properly polarized power cord.
•DO NOT connect this unit to a non-grounded, non-
polarized outlet.
•HIGH VOLTAGE is used in the operation of this equipment.
SEVERE IN- JURY OR DEATH may result if personnel fail to
observe safety precautions. Before working inside the
equipment, turn the power off and disconnect the power
cord.

1.2 Safety Information1
1-3
•Always replace the fuse with one of the same rating,
voltage, and type.
•Overhead clearance is required. DO NOT place this
instrument under a cabinet or other structure.
•DO NOT use this unit for any application other than
calibration work.
•DO NOT use this unit in environments other than those
listed in the user’s guide.
•DO NOT turn the unit upside down with the inserts in place;
the inserts will fall out of the unit.
•DO NOT operate near flammable materials.
•Use of this instrument at HIGH TEMPERATURES for
extended periods of time requires caution.
•Completelyunattended high temperature operation is not
recommended for safety reasons.
•Before initial use, after transport, and anytime the furnace
has not been energized for more than 10 days, the
calibrator must be energized for a dry-out period of 1 to 2
hours before it can be assumed to meet all of the safety
requirements of the IEC1010-1.
•Materials used in this furnace may be irritating to skin,
eyes, and respiratory tract. Consult the material
manufacturer’s MSDS (Material Safety Data Sheet). Proper
ventilation and safety precautions must be observed.
•Follow all safety guidelines listed in the user’s guide.
•Calibration Equipment should only be used by Trained
Personnel.
1.2.2
Cautions
Cautions
•To avoid possible damage to the instrument, follow these
guidelines.
•DO NOT plug the unit into 230 V if the heater switches and
fuse holder read 115 V. This action will cause the fuses to
blow and may damage the instrument.
•Components and heater lifetime can be shortened by
continuous high temperature operation.
•Most probes have handle temperature limits. Be sure that
the probe hand temperature limit is not exceeded in the air
above the unit.
•Allow for test probe expansion inside the well as the
furnace heats.
•DO NOT use fluids to clean out the well.

•Never introduce foreign material into the probe hole of the
insert. Fluids, etc. can leak into the calibrator causing
damage.
•DO NOT change the values of the calibration constants
from the factory set values. The correct setting of these
parameters is important to the safety and proper operation
of the calibrator.
•DO NOT drop or force the probe stems into the well. This
type of action can cause a shock to the sensor and affect
the calibration.
•DO use a ground fault interrupt device.

Introduction
The Hart Scientific 9150 thermocouple furnace can be used for calibrating ther-
mocouple and RTD temperature probes. Calibrations may be done over a range
of 150°C to 1200°C (302°F to 2192°F). Temperature display of the 9150 is 0.1
degrees below 1000°and 1 degrees above 1000°.
The furnace features:
• Rapid heating and cooling
•Interchangeable multiple hole probe sleeves
• Convenient handle
• RS-232 interface
Built in programmable features include:
•Temperature scan rate control
• Eight set-point memory
•Adjustable readout in °C or °F
The temperature is accurately controlled by Hart’s hybrid analog/digital con-
troller. The controller uses a Type S thermocouple as a sensor and controls the
well temperature with a solid state relay (triac) driven heater. The furnace should
be calibrated yearly by trained personnel at Hart Scientific.
The LED front panel continuously shows the current well temperature. The
temperature may be easily set with the control buttons to any desired tempera-
ture within the specified range. The calibrator’s multiple fault protection de- vices
insure user and instrument safety and protection.
The 9150 calibrator furnace was designed for portability, low cost, and ease of
operation. Through proper use, the instrument will provide continued accurate
calibration of temperature sensors and devices. The user should be familiar with
the safety guidelines and operating procedures of the furnace as described in
this manual.
