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.
