Press the "▲" button or "IRT" button to adjust the Emissivity.
Most (90% of typical applications) organic materials and painted or
oxidized surfaces have an emissivity of 0.95 (pre-set in the unit).
Inaccurate readings will result from measuring shiny or polished
metal surfaces. To compensate, cover the surface to be measured
with masking tape or flat black paint.
Allow time for the tape to reach the same temperature as the
material underneath it. Measure the temperature of the tape or
painted surface.
