  • Page 7: Mode Button Function

    MODE Button Function This infrared thermometer measures Maximum (MAX), Minimum (MIN), Differential (DIF), and Average (AVG) Temperatures. Each time you take a reading, this data is stored and can be recalled with the MODE button until a new measurement is taken. When the trigger is pulled again, the unit will begin measuring in the last mode selected.

  • Page 8: Cleaning

    Notes How it Works This REED Infrared Thermometer measures the surface temperature of an object. The unit’s optics sense emitted, reflected, and transmitted energy which is collected and focused onto a detector. The unit’s electronics translate the information into a temperature reading which is displayed on the unit.
  • Page 9 Emissivity Emissivity is a term used to describe the energy-emitting characteristics of materials. 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.
