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.

Service Information

• 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 al­lows 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.

www.GlobalTestSupply.com

4180, 4181

Operators Manual

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

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.

Cutout. If the Product exceeds the temperature set in the
soft cutout menu or if it exceeds the maximum operating
temperature of the Product a cutout condition occurs. If
this happens, the unit enters cutout mode and will not
actively heat or cool until the user issues this command to
clear the cutout or resets the instrument using the SET

PT. key to clear the cutout mode and activate the Product.
Reset. The software cutout may need to be adjusted for

the application. Check and adjust the cutout setting by
entering CUTOUT menu: MENU|TEMPSETUP|CUTOUT.

Operating Parameters. Ensure that all operating
parameters for the Product match the Report of
Certification that was sent with the Product.
