LASER POINTER

The laser icon will be displayed. Please take care to the explanations given regarding Distance: Spot-
Ratio.
ILLUMINATION
In bad light conditions the illumination can be switched on with q button during HOLD mode.
EMISSIVITY
The emissivity is a term used to describe the energy-emitting characteristics of a material. Most (90 %
of typical applications) organic materials and painted or oxidized surfaces have an emissivity of ,95
(pre-set in the unit). Inaccurate reading will result from measuring shiny or polished metal surfaces. To
compensate, cover the surface to be measured with masking tape. Press MODE button (5) and „E"
starts blinking. The required emissivity can be set with q / p buttons.
