  • Page 20: Start Up

    We recommend the use of the following programme: LDMTOOL (Version 4.5 or higher). When turning on the LLD-150-PROF2, it must be properly installed at the designated operation site, aimed at the target, and kept in a stable position. Targets to be measured (e.g. machine or system components) should preferably have a light and homogeneous surface.

  • Page 24: Dt - Distance Tracking

    DT mode can be chosen for distance measurement of different kinds of surfaces (varying reflectance). In this type of distance tracking mode, the LLD-150-PROF2 uses internal algorithms to continuously evaluate the quality of the Laser radiation signal that is coming back. This may cause longer measuring times in the case of poor reflectance or sudden jumps in distance.

  • Page 25: Dx - Distance Tracking With Target Board (50 Hz)

    DF mode allows a measurement that is triggered by an external trigger pulse. Initially, after selecting this mode, the operator does not receive any response. As soon as the trigger pulse has been detected, the LLD-150-PROF2 will send data and switches to digital and/or analog output.

  • Page 27: St - Display/Set Measure Time [0

    Measuring time is directly conditional on the selected measuring mode. As a general rule, one may say: the poorer the reflectance of the surface of a LLD-150-PROF2 will require particular target, the more time the to determine the distance with specified accuracy. For example, if error message E15 is output because of poor reflectance and insufficient time to measure, this latter setting must be increased.

  • Page 28: Sf - Display/Set Scale Factor

    An exception there from is zero-value. In this case, the LLD-150-PROF2 automatically picks the smallest possible time value for measurement! LLD-150-PROF2 comes factory-set with ST = 0.
