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.

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.
