IR Measurements

Taking Measurements

Point the meter toward the object being measured, then press and

hold the MEASURE button. The meter will turn ON and take a reading.

Read the measured temperature on the LCD. The meter turns off

automatically approximately 8 seconds after the MEASURE button is

released.

While pressing the MEASURE button:

Press the LASER button to turn on the laser pointer.

Press the MAX button to display and hold the highest reading. The

display will update with each higher reading.

The object being measured should be larger than the spot size as

illustrated in the distance to spot diagram.

Measurement considerations: If the surface of an object to be

measured is covered with frost, dust or other materials, surface

cleaning must be performed before accurate measurements can be

made. High Reflective Surfaces: If the surface of an object to be

measured is highly reflective with a very low emissivity value, apply

masking tape or apply flat black paint to the surface to raise to improve

the accuracy of the measurement.

Displaying °F or °C

Open the battery compartment, move the slide switch located in the

opening beneath the outermost battery

Battery Replacement

A flashing display indicates that the AAA batteries which power the meter

have weakened. Open the battery compartment on the rear of the meter,

replace the batteries and close the compartment.
