4.3 Measurement Procedures
4.3.1 Temperature Measurement
Hold the instrument by its handle, point the IR Sensor at the area
•
or object to measure, and press the Measurement Trigger.
While the Measurement Trigger is kept pressed, the instrument
•
will continuously measure and update the display with the
temperature of the object pointed at with the IR Sensor.
After the Measurement Trigger is released the instrument will
•
hold the last temperature reading for 7 seconds, then shut off
automatically.

To ensure accurate temperature measurements, make sure
•
that the target object is larger than the unit spot size, at the
measuring distance.
The smaller the target, the closer you should be.
•
For maximum accuracy, make sure that the target area is at
•
least twice as large as the spot size.

5.2 Cleaning
5.2.1 Lens cleaning
Debris or dirt on the lens may cause obstruction and reduce the
accuracy of the thermometer. If this occurs, either wipe the lens
with a Q-tip (moistened with water only) or blow the loose particles
off with clean compressed air. Do not use solvent on the lenses, as
it may damage the instrument.
5.2.2 Exterior cleaning
Periodically wipe the case with a soft damp cloth and mild household cleanser. Do not use abrasives or solvents. Ensure that no
water gets inside the instrument to prevent possible short circuits
and damage.
