OPERATING INSTRUCTIONS
Power
1. The meter is powered by one (1) 9V battery.
IR Measurements
1. Hold the meter by its handle and point it toward the surface to be measured.
2. Pull and hold the trigger to turn the meter on and begin testing. The temperature reading, the
flashing ‘SCAN’ icon, the emissivity, the unit of measure and other icons as shown in the
Display Description will appear. Note: Replace the meter’s 9V battery if the display does not
switch on.
3. Release the Trigger and the reading will hold for approximately 8 seconds (HOLD will appear on
the LCD) after which the meter will automatically shut off.
Temperature units
With the trigger pressed, press the ºF/ºC button to select the temperature units.
Backlight/Laser Pointer
With the trigger pressed:
1. Press the button once to change the state of the backlight (On or Off). When the laser is
on the laser icon will appear in the display.
2. Press the button again to change the state of the backlight (On or Off).
IR Measurement Notes
1. The object under test should be larger than the spot (target) size calculated by the field of view
diagram (printed on the side of the meter and in this guide).
2. Before measuring, be sure to clean surfaces that are covered with frost, oil, grime, etc.
3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface
before measuring. Allow time for the paint or tape to adjust to the temperature of the surface it is
covering.
4. Measurements through transparent surfaces such as glass may not be accurate.
5. Steam, dust, smoke, etc. can obscure measurements.
6. The meter automatically compensates for deviations in ambient temperature. However, it can
take up to 30 minutes for the meter to adjust to extremely wide changes.
7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and
down motion) until the hot spot is located.
