Safety Information
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.
The symbols used on the Product and in this manual are shown in Table 1.

Warning
To prevent eye damage and personal injury:
• Read all safety Information before you use the Product.
• Do not use the Product if it operates incorrectly.
• Use the Product only as specified, or the protection supplied by the
Product can be compromised.
• Before you use the Product, inspect the case. Do not use the Product if it
appears damaged. Look for cracks or missing plastic.
• See emissivity information for actual temperatures. Reflective objects
result in lower than actual temperature measurements. These objects pose
a burn hazard.
• Do not look directly into the laser with optical tools (for example,
binoculars, telescopes, microscopes). Optical tools can focus the laser and
be dangerous to the eye.
• Do not look into the laser. Do not point laser directly at persons or animals
or indirectly off reflective surfaces.
• Replace the batteries when the low battery indicator shows to prevent
incorrect measurements.
• Do not use the Product around explosive gas, vapor, or in damp or wet
environments.
• Use the Product only as specified or hazardous laser radiation exposure
can occur.

Performance Verification Tests

The subsequent performance tests verify the complete operation of the Product and check the accuracy of each
function against Product specifications. If the Product fails any part of the test, calibration adjustment and/or repair
is necessary. Product calibration can only be adjusted at the Fluke factory. To return your Product for calibration
adjustment, call one of the numbers in the “Contact Fluke” section of this document.
Read the entire Performance Tests section before you make any adjustment.

Required Equipment
Table 2 shows the required equipment necessary for the performance tests.

Note
Fluke recommends plate blackbodies as verification equipment because cavity blackbodies
have small field of view, which could increase uncertainty for a thermometer with low D:S. If
cavity blackbodies are used to verify the Product, make sure that the distance between the
cavity blackbody opening and the Product is equal to the diameter of the cavity blackbody
opening × 2. Where the temperature of the cavity tube near the outside is lower than the
temperature of the cavity, readings will be lower. Moving the 62Max closer to the cavity
opening may be necessary for the 62 Max to only measure the cavity temperature.
If other than Fluke blackbodies are used, the target should be checked for actual radiometric
output with a more accurate device, such as a Heitronic KT19-82.

[1] Calibrate with an IR thermometer that has low uncertainty such as KT19 and TRT.

Before the Performance Verification Tests

Before you do the performance verification tests:
• Performance verification tests are to be done within the temperature of 23 ±3 °C and between 25 % and 60 %
relative humidity.
• Make sure that all required calibration equipment has a valid calibration certificate and/or label.
• Make sure that any item(s) substituted for the equipment in Table 2 meets or exceeds the stated minimum use
specifications.
• The correct radiometric temperature will need to be determined before blackbodies are used to make
measurements.
• Make sure that the required calibration equipment is allowed a warm-up period as per manufacturer
recommendations. See the documentation for the equipment.

Performance Verification Tests

To prepare the Unit Under Test (UUT) for verification:

1. Visually inspect the UUT outer case for cracks or damage.
2. Open the battery compartment and inspect the battery and battery compartment for corrosion or damage.
3. Install a new AA battery prior to verification.
4. Close the UUT battery compartment door.
5. Set the UUT temperature units for degrees Celsius (°C) if necessary.
6. Push SEL until °C alone is shown. Change by pushing SET.

Performance Verification Test Procedures

Note
The subsequent verification test requires the blackbody emissivity to be set to 0.95 at all
temperature points.

Note
For temperatures below ambient, to reduce the chance of condensation or ice buildup on the
emitter plate of the 4180, it is recommended to install a clean dry air or nitrogen gas purge
box on the front of the 4180 Blackbody. Although the purge box is recommended, it is optional.
If temperature measurements are made without a purge box, refer to the 4180 User Manual
for how to make proper temperature measurements below ambient. See Figure 3.

Calibration Information

1. Set blackbody emissivity and temperature for the first temperature listed in Table 3. Allow adequate time for the
blackbody to stabilize. See the blackbody documentation.
2. Position the UUT at the correct the distance from the blackbody listed in Table 3. Center the UUT laser(s) on the
blackbody emitter plate. For the 62 MAX +, make sure that the midpoint of the two laser spots is centered on the
blackbody plate. The 62 Max uses one laser.
3. Push and hold the UUT trigger for 5 to 6 seconds.
4. Release the trigger.
5. Record the UUT indication.
6. Move to a location that is not centered on the blackbody.
7. Make sure the UUT reading is within the limits listed in Table 3.
8. Repeat steps 1 through 7 for the remaining temperatures listed in the Temperature column of Table 3. The
62 Max is specified to 500 °C. 461 °C is the last temperature point to verify.
9. Set blackbodies to nominal values.

[1] Distance is calculated based on the target size. Typically a spot size that is about 1/2 the target size provides the best results.

Note
Fluke recommends plate blackbodies as verification equipment because cavity blackbodies
have small field of view, which could increase uncertainty for a thermometer with low D:S. If
cavity blackbodies are used to verify the Product, make sure that the distance between the
cavity blackbody opening and the Product is equal to the diameter of the cavity blackbody
opening × 2. Where the temperature of the cavity tube near the outside is lower than the
temperature of the cavity, readings will be lower. Moving the 62Max closer to the cavity
opening may be necessary for the 62 Max to only measure the cavity temperature.
Temperature verification is complete. If the Product does not pass the performance verification tests, calibration
adjustment or repair is necessary. Product calibration can only be adjusted by Fluke. To return your Product for
calibration adjustment, call one of the numbers in the “Contact Fluke” section of this document.

Blackbody Layout
Make sure that the distance between two blackbodies is more than 1 meter. Forced air or HVAC vents should not be
near the surface of the radiation source. Do not have two blackbodies work face to face. For more detail about
blackbody use, see the Fluke 4180 Technical Guide.
