The Thermometer turns on when you press the trigger.
The Thermometer turns off when no activity is detected for 8 seconds.
To measure temperature, aim the Thermometer at the target, pull and hold the trigger.
Release the trigger to hold a temperature reading.
Be sure to consider distance-to-spot size ratio and filed of view. The laser is used for aiming
only.
LOCATING A HOT OR COLD SPOT
To find a hot or cold spot, aim the Thermometer outside the target area. Then, slowly scan
across the area with an up and down motion until you located the hot or cold spot. See Figure 5.
DISTANCE AND SPOT SIZE
As the distance (D) from the target being measured increases, the spot size (S) of the area
measured by the unit becomes larger. The spot size indicates 90% encircled energy. The
maximum D:S is obtained when the Thermometer is 600mm (60 in) form the target resulting in a
spot size of 20mm (2 in). See Figure 6.
