3. SET UP
3.1.
Installing/Changing Battery (fig.1)
3.1.1.
On either side of the trigger, where the handle moulding meets the main
body there are two very shallow recesses. Place thumb and finger into
these recesses and pull the front section of the handle forward and down to
reveal the battery compartment.
3.1.2.
Attach the battery connector to the battery terminals and place the battery
into the battery compartment making sure that the connection leads will not
foul the cover when it is closed.
3.1.3.
When the ‘battery low’ indicator appears on the display replace the battery
immediately, (See Enviromental Protection).

4. OPERATION AND APPLICATION
4.1
Depress the trigger (1) in fig 3 to switch on the unit, the 'SCAN' icon will
illuminate.
4.2 Decide what units are required by pressing the '°C/°F' button (3) in fig 3. The
button will toggle between the specified units.
4.3 Pay attention to the distance from the thermometer to the target as the target
surface size increases with distance. A ratio of 12:1 exists, see fig 2.
Make sure the target is larger than the unit's spot size. The smaller the
target, the closer the distance "D". When accuracy is critical ensure the
target is at least twice the spot size.
4.4
The unit is equipped with a laser for the purpose of aiming only. With the
laser button (2) in fig 3 in the 'on' or 'off' mode, aim at the target surface and
depress the trigger. The temperature of the target surface will be displayed
on the LCD display screen. When the trigger is released the reading will be
held for 7 seconds approximately; the 'HOLD' icon will be illuminated in this
period; and then the thermometer will automatically shut down unless the
trigger is depressed again.
4.5
To locate a hot spot on a large surface, aim the thermometer as in 4.4,
then scan across the area with a controlled uniform "zig-zag" sweep until you
locate the spot, as illustrated in fig 4.

5. NOTES ON EMISSIVITY
5.1
Emissivity is a term used for the ability of a surface to radiate energy. This unit has been pre-set with an emissivity of 0.95, which
makes it suitable for 90% of typical applications.
5.2 Inaccurate results will occur when targeting shiny or polished surfaces. As a tip, apply a non reflective tape to the area to be tested,
allowing time for the surface temperature of the tape to reach that of the substrate.
6. CLEANING
6.1
The sensor lens is delicate and should be kept clean at all times. Use a cotton bud and medical alcohol, allowing lens to dry. The
casing can be cleaned with a moist cloth and mild soap but never submerged.
