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.
4.3.2 Field of view or measurement target area
Spot
(D/10)
Resolution
0.1 ° C • To ensure accurate temperature measurements, make sure
that the target object is larger than the unit spot size, at the
measuring distance.
1 ° C
• The smaller the target, the closer you should be.
0.1 ° F
• For maximum accuracy, make sure that the target area is at
least twice as large as the spot size.
