Emissivity, Maintenance, Replace Battery

Infrared Recorder

•Emissivity

Emissivity is a term used to describe the energy-emitting characteristics of materials. The higher of this value means the more capability of radiation emittance the materials has. Most organic materials and painted or oxidized surfaces have an emissivity of 0.98. Metal surfaces or shiny materials has a lower emissivity and give inaccurate readings. Please note this during applications.

•Maintenance

Blow off loose particles using a lens blow. Gently brush remaining debris away with a lens brush. Carefully wipe the surface with a moist cotton swab. The swab may be moistened with water.

NOTE: Don't use solvents to clean the glass lens.

•Replace Battery

When the battery voltage drops below that required for reliable operation, the low battery

symbol will appear, indicating it is the time to replace the battery.

To change the 9V battery, detach the battery compartment cover by pushing the engraved pattern on the handle and pull down. Change the 9V battery with new one and put the battery cover back.
