strike your eye.
 Do not allow the laser light beam impinge on any gas
which can explode.

Field of View
The Infrared Thermometer’s field of view is 8:1,
measuring that if the Infrared Thermometer is 8
inches from the target, the diameter of the object
under test must be at least 1 inch. Other distances are
shown below in the field of view diagram. Refer to the
chart printed on the meter for more information.

Field of View:
Make sure that the target is larger than the unit’s spot
size.
The smaller the target, the closer you should be to it.
When accuracy is critical, make sure the target is at
least twice as large as the spot size.

6. Measurement Operation
6-1. Hold the meter by its Handle Grip and point it
toward the surface to be measured.
6-2. Pull and hold the trigger to turn the meter on and
begin testing. The display will light if the battery is good.
Replace the battery if the display does not light.
6-3. while measuring, the SCAN display icon will appear
in the upper left hand corner of the LCD.
6-4. While continuing to pull the trigger:
 Push the “Laser/Backlight” button once to turn on the
laser pointer. When the laser is on, the laser icon
will appear on the LCD.
Push the “Laser/Backlight” button two times to turn on
the backlight.
Push the “Laser/Backlight” button three times to turn
the laser off.
Push the “Laser/Backlight” button four times to turn
both the laser and backlight off.
 Select the temperature units (˚C or ˚F) using the “˚C/˚F”
buttons.
 Select the Max/Min mode using the “Max/Min”
buttons.
6-5. Release the trigger and HOLD display icon will
appear on the LCD indicating that the reading is being
held.

6-6. The meter will automatically power off on
approximately 8 seconds after the trigger is released.
Note: Measurement Considerations
Holding the meter by its handle, point the IR Sensor
toward the object whose temperature is to be
measured. The meter automatically compensates for
temperature deviations from ambient temperature.
Keep in mind that it will take up to 30 minutes to adjust
to wide ambient temperatures are to be measured
followed by high temperature measurements, some
time (several minutes) is required after the low (and
before the high) temperature measurements are made.
This is a result of the cooling process which must take
place for the IR sensor.

1. Battery
Replacement
7-1. As battery
power is not
sufficient, LCD will
display
replacement with
one new battery
type 9V is required.
7-2. Open battery
cover, then take
out the battery from instrument and replace with a
new 9-Volt battery and place the battery cover back.
7. Notes
8-1. How it works
Infrared thermometers measure the surface
temperature of an object. The unit’s optics sense
emitted, reflected, and transmitted energy, which is
collected and focused onto a detector. The unit’s
electronics translate the information into a temperature
reading which is displayed on the unit.
8-2. Field of View
Make sure that the target is larger than the unit’s spot
size. The smaller the target, the closer you should be to

it. When accuracy is critical, make sure the target is at
least twice as large as the spot size.
8-3. Distance a hot spot
As the distance (D) from the object increases, the spot
size (S) of the area measured by the unit becomes larger.
8-4. Locating a hot spot
To find a hot spot aim the thermometer outside the area
of interest, then scan across with an up and down
motion until you locate hot spot.
8-5. Reminders
 Not recommended for use in measuring shiny or
polished metal surfaces (stainless steel, aluminum, etc.).
 The unit cannot 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 obstructing the unit’s optics
