D. EMISSIVITY
Emissivity: Most organic materials and
painted or oxidized surfaces have an
emissivity of 0.95(preset in the unit).
Inaccurate readings will result from
measuring shiny or polished metal
surfaces. To compensate for this, adjust
the units emissivity reading or cover the
surface to be measured with masking
tape or flat black paint. Measure the
tape or painted surface when the tape
or painted reach the same temperature
as the material underneath.
E. OPERATION
1. Operating the unit:
1 ) Open the battery door and insert the battery.
2) Pull the trigger to turn on the unit;
3) Aim at the target surface and pull the trigger, then temperature will be shown on the LCD.
This unit is equipped with a laser, which is only used for aiming.
2. Locating a Hot Spot:
To find a hot spot, aim the thermometer outside of interest, then scan
across with an up and down motion until you locate the hot spot.
