NON-CONTACT INFRARED TEMPERATURE MEASUREMENTS
1. Rotate the function switch to the IR position. The upper right four digit temperature display will
switch on.
2. Press the MODE button to select °F or °C.
3. Aim the infrared sensor (top of meter) at the surface to be measured.
4. Press and Hold the IRT button to turn on the IR thermometer and laser pointer. The laser
pointer identifies the surface spot to be measured and “SCAN” will flash in the display.
5. Read the temperature in the display.
6. The area of the surface to be measured must be larger than the spot size as determined by the
distance to spot size values listed in the specification table.
7. Release the IRT button to turn the IR thermometer and laser pointer off. “HOLD” and the
final measured value will remain in the display.
WARNING: Do not directly view or direct the laser pointer at an eye. Low power visible lasers
do not normally present a hazard, but may present some potential for hazard if viewed directly for
extended periods of time.
IR Spot to Distance Diagram
The 4:1 spot to distance ratio determines the size of the measured surface area with respect to the
distance the meter is held away from the surface.
IR Measurement Notes
1. The object under test should be larger than the spot (target) size calculated by the field of view
diagram.
2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking
measurements.
3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface
before measuring.
4. The meter will not make measurements through glass steam, dust, and smoke.
5. 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.
