  • Page 63 User Guide Signal Processor Distance: The distance between the two thermometer locations. Default 1.0m (or 1.0 ft, depending upon the units used when configuring the speed channel). If the on-line speed sensor provides an output of RAM speed then the die scaling factor will need to be entered (see Section 4.5.3).

  • Page 64: Quench Rate Manual Mode (Quench M)

    Signal Processor User Guide 4.5.6 Quench Rate Manual Mode (Quench M) The configuration for this quench rate mode is almost identical with the following exceptions: There is no die scaling factor to configure. There is now a unit of distance to select as either metres or feet. (Default = meters) There is also a speed value depending up on the unit selected above.
