4.3 Measurement Procedures
4.3.1 Temperature Measurement
•
Hold the instrument by its handle, point the IR Sensor to the
area or object to measure, and press the Measurement Trigger.
•
While the Measurement Trigger is kept pressed, the
thermometer is continuously measuring the temperature of the
object pointed at, with the IR Sensor.
•
When the Measurement Trigger is released the instrument will
hold the last temperature reading for 7 seconds, and then shut
off automatically.
4.3.2 Field of view or measurement target area
•
To take the most accurate temperature measurements, make
sure that the target object is larger than the unit spot size, at any
given 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.
