Specifications
Temperature Range: -50°C to 1350°C (-58°F to 2462°F)
Field of View (Figures D–F)
The farther the thermometer is from a target, the larger the
target area will be, this is known as the distance to spot
(D:S=20:1) ratio. For example: at a distance of 508 mm the spot
will be 25.4 mm in diameter. The thermometer will display the
average temperature across the target area.
DISTANCE: SPOT = 90% Energy
DISTANCE: SPOT ratio 20:1
nOTE: For best accuracy make sure the object to be measured
is larger then the thermometer’s spot size.
The thermometer has a visible red laser point
26
in the centre
of eight outer dots. The red laser point shows the approximate
location where the temperature is being measured. The outer
dot pattern will become larger with distance. Figure E shows the
laser point and outer dots near, Figure F shows the laser point
and outer dots farther away.
nOTE: The laser point is only an approximate location, it is not
an exact location.
MAINTENANCE
To Clean the Lens
Blow off loose dust and dirt with compressed air. Carefully wipe
the surface with a moist cotton swab. Don’t use abrasive or
solvent.
To Clean the Thermometer Housing
Use soap and water on a damp soft cloth. Don’t use abrasives
or solvent.
nOTE: Do not immerse the thermometer in water, and do not
let any liquid enter the case.
Basic Measurement Procedure
1. Hold the thermometer by its handle, and point it toward the
surface to be measured.
2. Pull and hold the trigger for at least 1 sec to turn on the
thermometer and take measurement. Reading will be
displayed on the main display.
nOTE: Each time the trigger is pulled, the pull must last at
least 1 sec. The laser pointer (26, Figure F) is for reference
only.
3. During measurement, the symbol SCAN will flash on
the main display, and when the trigger is released, the
measurement stops and the symbol HOLD appears
indicating that the last reading is locked.
4. The thermometer will turn off automatically after about 50
seconds if the trigger or no buttons are pressed.
nOTE:
• Make sure the target surface is larger than the
thermometer’s spot size. The smaller the target surface, the
closer you should be to it (Refer to Field Of View section).
When accuracy is critical, make sure the target is at least
twice as large as the spot size.
• To find a hot or cold spot, aim the thermometer outside
the desired area 25 . Press and hold the trigger, slowly scan
back and forth across the area until you locate the hot or
cold spot. Refer to Figure C.
Measurement Considerations
• Laser beam is mainly used to locate far objects. To save
battery power, disable the laser function when measuring
near objects.
• The thermometer can not measure through transparent
surfaces such as glass. It will measure the surface
temperature of the glass instead.
• Steam, dust, smoke, etc., can prevent accurate measurement
by interfering with the energy emitted from the target.

the MODE button until the symbol stops flashing. The
thermometer returns to normal operation.
