The menu functions are selected by moving the highlighted cursor using the up and down directional buttons.
Menu items are edited using hot buttons 2 & 3 which are labelled + and -. Hot button 1 is always available to
take you “back” one menu sub-level, whilst hot button 4 is always available to “exit” the menus completely.

3.4.7.1 Measurement Settings
• Emissivity – The user can select the emissivity for the material being imaged. To achieve
correct temperature measurement the emissivity value must be set correctly. An emissivity
lookup table is included in Section 6.
NOTE: Caution should be observed in using the emissivity control – the user should explore
the effect on the observed temperature of an object when different emissivities are
selected. Low values of emissivity should be used only with extreme caution as large
errors in temperature readings may be obtained with only small errors in emissivity.
Care should also be taken to avoid reflections from hot/cold objects in the vicinity.
