Page 15: Functional Description And Operating Instructions
The majority of applications are measured with an emissivity of 0.95. The CMAC 4230 is therefore preset to 0.95 and can be adjusted in steps of 0.01 depending on the application. Emissivity range over 1.00 is intended for applications, where adjacent measurement objects having different temperatures are to be measured. -

Page 29: Emissivity
Most organic materials as well as lacquered and oxidized surfaces have an emissivity of 0.95. The emissivity is preset to 0.95 in the CMAC 4230 for this reason, but can be changed using the rocker switch. The determination of the temperatures of shiny or highly polished metal surfaces results in inaccurate measured values. -
