Introduction
The Fluke Calibration 4180, 4181 Precision Infrared Calibrator (The Product) is a portable instrument
or bench-top temperature calibrator used to calibrate point IR thermometers. The Product is small
enough to use in the field, and accurate enough to use in the lab.
The Product features:
• Rapid heating and cooling
• RS-232 interface capability
Built in programmable features include:
• Temperature scan rate control
• Eight set-point memory
• Adjustable readout in °C or °F
• Adjustable Emissivity
The temperature is accurately controlled by the digital controller. The controller uses a precision
platinum RTD as a sensor and controls the surface temperature with a solid state relay (triac) driven
heater (4181) and FET driven Peltier modules (4180).
The LCD (display) continuously shows the current temperature. The temperature is easily set with the
control buttons to any desired temperature within the specified range. The Product's multiple fault
protection devices ensure user and Product safety and protection.
With proper use, the Product will provide continued accurate calibration of IR temperature
measurement devices. Familiarize yourself with the safety guidelines and operating procedures of the
Product. See Safety Information.

Safety Information
General Safety Information is located in the printed Safety Information document that ships with the
Product. It can also be found online at www.Flukecal.com. More specific safety information is listed
where applicable in this manual.
A Warning identifies conditions and procedures that are dangerous to the user. A Caution identifies
conditions and procedures that can cause damage to the Product or the equipment under test.
Follow these guidelines closely to make sure that the safety mechanisms in this Product operate
properly. This Product must be plugged into an AC-only outlet according to the Specifications and
Environmental Conditions. The power cord of the Product has a three-pronged grounding plug for your
protection against electrical shock. Plug the power cord directly into a properly grounded three-prong
receptacle. The receptacle must be installed in accordance with local codes and ordinances. Consult a
qualified electrician.
WCaution
To prevent damage to the Product:
• Always replace the fuse with one of the same rating, voltage, and type.
• Always replace the power cord with an approved cord of the correct rating and type.
• Protect the target against dirt and damage - scrapes and scratches. A well-kept target
surface, free from dirt and damage, produces better measurements. Use the target
cover whenever the Product is not in use to protect the target. Always use the target
cover when transporting the Product, but remember to never transport the Product
when the target temperature is >50 °C.
• Do not touch the target. Oils and salts from the skin will permanently damage the
target surface at high temperatures.
• Do not use fluids to clean the target surface.
• Do not use shop air to clean the target surface. Oil and contaminants in the shop air
could contaminate the surface.
• Do not use canned, compressed air (used to clean a computer) to clean the target
surface. Chemicals in the air could contaminate the target surface.
• When ice forms on the target, change the instrument set-point >50 °C to melt the
excess ice. DO NOT wipe the front plate (target). Change the set-point to 100 °C or
higher to evaporate the excess water.

• Do not force cool the surface. The surface should not be cooled by any method other
than natural convection. Forced air can often have oil or water in it. Even water can
leave mineral deposits on the surface. Trying to cool the surface too quickly can also
cause thermal shock to the emissive surface.
• Do not use liquid nitrogen (LN2) to quick cool the target.
• Do not plug the Product into 230 V if the fuse holder reads 115 V. This action will
cause the fuses to blow and may damage the Product.
• Component lifetime can be shortened by continuous high temperature operation.
• Do not change the values of the calibration constants from the factory set values.
Calibration constants shall only be changed by qualified and authorized personnel.
The correct setting of these parameters is important to the safety and proper
operation of the Product.
• Use a ground fault interrupt device.
• Always operate this Product at room temperatures as stated in Specifications and
Environmental Conditions.
• The Product is a precision instrument. Handle the Product with care. It is important to
keep the calibration well and the IR target surface clean and clear of any foreign
matter.
• If a main supply power fluctuation occurs, immediately turn off the Product. Wait until
the power has stabilized before re-energizing the Product.
• Always carry the Product in an upright position. The convenient pull-up handle al-
lows one hand carrying.
• Do not operate the instrument in excessively wet, oily, dusty, or dirty environments.
• DO NOT operate near flammable materials.
• Use the target cover at temperatures below ambient (25 °C). If ice or liquid water
forms on the target, IR thermometers will not indicate the correct temperature.

Ice Buildup and Purge Procedure (4180 Only)
At the factory, the Product calibration is done with the target free of any ice or moisture. Ice or moisture
on the target changes the emissivity of the target and apparent temperature. If there is any ice or
moisture (even though it is a slight amount) on the target, the display temperature accuracy is invalid.
In addition, ice buildup can damage the surface coating causing the radiometric calibration to drift.
Always avoid ice buildup. To facilitate this, use the cover with a purge inlet provided with the Product.
Fluke Calibration recommends that the target cover be used at any set-point below the dew point.
Depending on the ambient humidity of the environment where the target is used, the dew point can be
as high as the ambient temperature of that environment.
Purge Procedure
The Cover allows the target to be used at temperatures below the dew point. The target is less likely to
form ice while the target is covered. The target cover has a purge inlet to further prevent ice buildup. To
use the purge, the user needs a 6 mm (0.25 in) outside diameter tube. Connect tubing to the purge inlet
on the target cover. Use a dry gas for the purge. This means the gas should have a dew point
<-15 °C. Fluke Calibration recommends nitrogen or dried air. If the gas contains any water vapor, ice or
moisture will form on the target. Use a relatively-low flow rate of 2.4 liters/min to 4.8 liters/min (5 CFH to
10 CFH) for the purge.

4180, 4181
Operators Manual
12
Do not leave the target uncovered for more than 5 seconds, since it can cause ice to form on the target.
To make measurements below the dew point:
1. Put the target cover in place.
2. Adjust the set-point to the desired temperature and allow the instrument to stabilize at that
temperature.
3. Remove the target cover when the target stabilizes.
4. Take a sample.
5. Replace the target cover.
Remove the Ice Buildup on the Target
If a small amount of ice has formed, place the cover back on the target and allow the purge gas to
sublime the ice. If there is more ice or you do not have a purge available, change the Product set-point
to a temperature equal to or greater than 50 °C with the target uncovered. Allow all ice to melt and all
water to dry before returning target to use. Do not wipe the target.
Set the Emissivity of the IR Thermometer
The Product is calibrated with a radiometric calibration. This calibration is done with a highly accurate
IR thermometer. This IR thermometer emissivity setting is 0.950 during Product calibration. When you
calibrate IR thermometers with the Product, it is best practice to use an IR thermometer emissivity
setting of 0.950. Some IR thermometers do not have an adjustable emissivity setting. Most of these will
have emissivity set at 0.95. In either case, the apparent emissivity setting of the Product should also be
set to 0.95. Due to safety issues and the physical limits of the instrument, temperature range of the
instrument may be limited from the specified range when using an emissivity setting other than 0.95. A
table of this limitation is shown in Table 5.
If the IR thermometer does not have an emissivity setting of 0.95, the Product allows adjustment of
emissivity (IRT ɛ, from 0.90 to 1.00). Refer to Forced Air and Convection for information on how to
access IRT ɛin the controller menu.

Precision Infrared Calibrator

If uncertain of the emissivity setting of the IR thermometer you are calibrating, consult your IR
thermometer's User's Guide or your IR thermometer's manufacturer.
Table 5. Apparent Temperature Limits
Forced Air and Convection
Since the Product has a large surface area, a major component of the temperature uncertainty is
caused by changes in convection. Because of this, keep the Product away from areas with large
amounts of air flow or drafts.
