• Do not stare into laser beam.
• Do not point laser directly at eye or indirectly off reective surfaces.
• For use by competent persons only.
• Do not point laser directly at eye or indirectly off reective surfaces.
• Replace the batteries as soon as the low-battery indicator appears.
• Verify the Tester’s operation by measuring on a known voltage source. Do
not use the thermometer if it operates abnormally.
• Do not operate the thermometer around explosive gas, vapor, or dust.
• To avoid a burn hazard or re, know that reective objects may be much
hotter than the indicated temperature reading.
• Do not leave the thermometer on or near objects of high temperature.
• If the thermometer is used in a manner not specied by this manual,
the protection provided by the thermometer may be impaired or may
result in hazardous laser radiation exposure.
Cautions

HOW THE THERMOMETERS WORK
Infrared thermometers measure the surface temperature of an object. The
thermometer’s optics sense emitted, reflected, and transmitted energy, which
is collected and focused onto a detector. The unit’s electronics translate the
signal into a temperature reading which the unit displays .
OPERATING THE THERMOMETER
Temperature Measurement
The Thermometer turns on when you press the trigger
The Thermometer turns off when no activity is detected for 8 seconds.
To measure temperature, point the thermometer at an object and pull the
trigger. You can use the laser pointer to help aim the thermometer. Pull and
hold the trigger when measuring the target surface. When release the trigger,
the display will hold the reading for 8 seconds. Be sure to consider distanceto-spot size ratio and field of view. The laser is used for aiming only and is not
related to temperature measurement.

The thermometer features an auto off function that automatically powers
down the thermometer after 8 seconds of inactivity. To turn the thermometer
on, pull the trigger.
