    Chapter - 4 A. PC Software Installation The provided AST software offers possibilities to connect pyrometer for parameter Setting, offline graph and to evaluate measuring data. A. 4.1 Installation Install the pyrometer software using the installation guide file on CD ROM. After installation of the software restart the computer and double click on application, it will open software screen.
  • Page 12 A. 4.2.2Parameter Setting All user selectable device parameters can be set by using the software in the Panel "Parameter". A) Emissivity settings : The emissivity can be set by clicking on "Parameters” and select or type in the desired emissivity directly in the description field.
  • Page 13 Auto : “Auto” mode is used for discontinuous measuring task, such as object being transported on a conveyor belt in such a case the maximum value for each object has to be indicated. When the object passes the measuring beam of the pyrometer, the maximum value is stored until a new hot object appears in the measuring beam.
