    User Guide Landmark Graphic Signal Processor Time Function Processing 4.1 Peak Picker The Peak Picker function can be used to monitor the highest temperature measured by the thermometer. This feature is useful especially for moving targets and/or where the target is obscured partially e.g. a steel slab on a rolling mill where parts of the surface are covered with scale.

  • Page 32: Track And Hold

    Landmark Graphic User Guide Signal Processor 4.2 Track and Hold Refer to Fig. 28. The Track and Hold time function is useful especially for measuring intermittent processes e.g. items on a conveyor belt. The pres- ence of a ’hot’ object can be used to activate the ‘Track’ function, which causes the output to display the temperature of the object.

  • Page 33: Averager

    User Guide Landmark Graphic Signal Processor 4.3 Averager Refer to Fig. 29. The Averager time function can be used to ‘smooth’ the temperature output signal in relation to the temperature input. The aver- ager response can be adjusted to suit your application. With a fast response speed, the temperature output signal tracks the input signal closely, any rapid fluctuations in the input are reflected in the output. With a slow response speed, the temperature output signal is much smoother, displaying more the...
