To adjust the unit’s emissivity value for a
material with unknown emissivity, plug in the
probe.
Pull the unit’s trigger. Place the measuring
tip of the probe on the area to be measured.
Wait for the reading to stabilize.
Note the indicated probe temperature reading.
Release the trigger.
Pull the trigger again. Measure the same area
using infrared measurement.
Press the emissivity button. Use the Up and
Down keys to select the material name “Free”
which will be shown in the display. Press the
emissivity button again until the emissivity sign
flashes. Use the arrow keys to change the
emissivity value until the temperature matches
the probe’s reading.

EMISSIVITY
Target
The amount of infrared energy radiated by an
object depends on its emissivity and its
temperature.
The emissivity depends on the material and its
surface characteristics.
Note:
For more accurate readings, adjust the
emissivity value for the type of material being
measured.
