Fluke 62 MAX Calibration Information

62 Max/62 Max +
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.
