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.

Product Overview
The Fluke Calibration 9190A Ultra-Cool Drywell (the Product or Calibrator) is a bench-
top temperature calibrator that can calibrate precision temperature instruments from
−95 °C to 140 °C (see Figure 1-1).
The Calibrator has two models: the 9190A and the 9190A-P. The 9190A-P is a “Process”
version of the 9190A that combines the heat source with a built-in thermometer input
panel. The Input Panel includes an input for an external reference/control thermometer
that makes it possible to perform a transmitter loop calibration, comparison calibration, or
a simple check of a temperature sensor. In addition, the Input Panel can read resistance
and current from a probe. For probes that require power to operate, the 4-20 mA input has
a loop-power function that can source up to 24 volts of power.

This product complies with the WEEE Directive (2002/96/EC) marking requirements.
The affixed label indicates that you must not discard this electrical/electronic product
in domestic household waste. Product Category: With reference to the equipment
types in the WEEE Directive Annex I, this product is classed as category 9 "Monitoring
and Control Instrumentation” product. Do not dispose of this product as unsorted
municipal waste. Go to Fluke’s website for recycling information.
 Warning
To prevent possible electrical shock, fire, or personal injury:
•Read all safety Information before you use the Product.
•Use the Product only as specified, or the protection
supplied by the Product can be compromised.
•Use this Product indoors only.
•Do not use the Product around explosive gas, vapor, or in
damp or wet environments.
•Do not use and disable the Product if it is damaged.
•Use only the mains power cord and connector approved for
the voltage and plug configuration in your country and rated
for the Product.
•Replace the mains power cord if the insulation is damaged
or if the insulation shows signs of wear.
•Make sure the ground conductor in the mains power cord is
connected to a protective earth ground. Disruption of the
protective earth could put voltage on the chassis that could
cause death.
•Do not put the Product where access to the mains power
cord is blocked.
•Use caution when you install and remove probes and
inserts from the Product. They can be hot.

•Do not touch voltages > 30 V ac rms, 42 V ac peak, or
60 V dc.
•Do not apply more than the rated voltage, between the
terminals or between each terminal and earth ground.
•Do not touch the well access surface of the instrument.
•Do not turn off the product at block temperatures higher
than 100 °C. Select a SETPOINT less than 100 °C and let the
instrument to cool before turning it off.
•Use the correct terminals, function, and range for
measurements.
•Do not use test leads if they are damaged. Examine the test
leads for damaged insulation, exposed metal, or if the wear
indicator shows. Check test lead continuity.
•Do not touch the probes to a voltage source when the test
leads are connected to the current terminals.
•Keep fingers behind the finger guards on the probes.
•Do not exceed the Measurement Category (CAT) rating of
the lowest rated individual component of a Product, probe,
or accessory.
Manual Set
The Calibrator includes an Operators Manual and a Getting Started Manual. Both
manuals are online at www.flukecal.com and on a CD in the Accessory Kit.
This 9190A Operators Manual contains feature information, operation instructions, and
basic user maintenance and troubleshooting information.
The 9190A Getting Started Manual is translated and contains basic information to
quickly set up and use the Calibrator.
The 9190A Product CD contains the Operators Manual, the Getting Started Manual, and
the 9190A Remote Operation interface drivers.

Notes:
[1] – For ambient temperature of 23 °C.
[2] – Time from when the SETPOINT is reached to when the unit is with in Stability specification.
[3] – The temperature range may be limited by the reference probe connected to the readout. The built-in Reference Accuracy does not
include the sensor probe accuracy. It does not include the probe uncertainty or probe characterization errors.
[4] – Measurement accuracy specifications apply within the operating range and assume 4 wires for PRTs. With 3-wire RTDs add 0.05 Ω
to the measurement accuracy plus the maximum possible difference between the resistances of the lead wires.
[5] – The thermocouple input readout is sensitive to EM fields in the frequency range of 500 MHz to 700 MHz.
