Operating Instructions
1. Hold the meter by its Handle Grip and point it toward the surface to be measured. Read the
Field of View section below for distance to target ratio information.
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.
3. While continuing to pull the Trigger:
a. Push the Laser button to switch the laser pointer ON. When the laser is on, the laser
icon will appear on the LCD over the temperature reading. Aim the red beam
approximately a half inch below the point of test (pressing the Laser button again turns the
laser off).
b. Select the temperature units using the
o
C /
o
F button.
c. Push the backlight button to switch ON the LCD backlighting function.
4. Release the Trigger; the reading will hold for approximately 6 seconds, after which the meter will
automatically shut off.
5. The meter defaults to the programmed conditions in use when the meter was last switched off.
For example, if the laser is set to ON and the temperature units are set to
o
F at the time the unit
is switched OFF, the unit will switch ON and use the same settings.
Over-range Indicator
If the temperature measurement exceeds 500°F (260°C), the thermometer will display dashes in
place of a temperature reading.
Field of View
The meter’s field of view is 6:1. For example, if the meter is 12 inches from the target (spot), the
diameter of the target must be at least 2 inches. Other distances are shown below in the field of
view diagram.
Note that measurements should normally be made closer than 2 feet from the target. The meter can
measure from further distances but the measurement may be affected by external sources of light.
In addition, the spot size may be so large that it encompasses surface areas not intended to be
measured.
