Calibration Information

Safety Information

To avoid possible personal injury:

• The information provided in this manual is for the use of qualified personnel

only. Do not perform the verification tests or calibration procedures
described in this manual unless you are qualified to do so.

• Performance of procedures other than those specified herein may result in

hazardous light exposure.

• Do not stare into the laser beam or direct it toward the eyes.

To avoid possible damage to the thermometer and to ensure correct
measurements:

• The Fluke 65 Infrared Thermometer contains parts that can be damaged by

static discharge. No procedure in this document requires the case to be
opened. If you do so, follow the standard practices for handling static
sensitive devices.

A Warning

Caution

• Do not drop the thermometer or subject it to violent shocks.

• Do not operate the thermometer near large electrical or magnetic fields.

• Do not touch the object with the thermometer.

• Keep the thermometer away from direct sunlight or strong sources of light,

hot objects (70 °C / 158 °F), high temperatures, high humidity, or dust during
use and storage.

• Do not apply sudden temperature changes to the thermometer. Before

taking measurements, wait for the thermometer to return to a stable
temperature.

• During performance tests and calibration, expose the thermometer to the

blackbody heat source only long enough to complete the measurement
(< 15 seconds). Between measurements, move the thermometer to an area
not affected by the heat source.

• Do not touch the focal lens.

• Condensation may form on the focal lens if the thermometer moves quickly

from a cold to a hot environment. Before taking measurements, wait for the
condensation to dissipate.
