Manual Operation
The hand held version of the Lasercheck head is supplied with base plate on the bottom. This will align the head
within specification on flat surfaces. If surfaces are cylindrical, then optional alignment feet should be used. For
surfaces with different geometry, alignment fixturing should be used. An understanding of alignment principals
of Lasercheck is required for development of fixturing. Please read the section “LASERCHECK ALIGNMENT
PRINCIPALS AND PRECEDURES” later in this manual to understand principals of alignment.
When performing measurements, set the rotational orientation so that the long axis of the head is
perpendicular to the dominant “lay” of the surface that you wish to measure. The long axis of the head
determines the direction of measurement in the same way that the direction of motion of a stylus on a stylus
gage determines the direction of measurement.
Automated Operation
The Lasercheck can be used with external inputs to start and stop the measurements in an automated
installation. Trigger input is Digital IN 1 or Pin 1 of connector J7. See the communications protocol section of
this manual for detailed information on commands utilizing external triggering. Triggers can also be routed
through external electronics, which use this information to time roughness requests to the Lasercheck system.
There are two common modes for automated applications. One is for continuous surface applications in which
numerous measurements are taken between one start input and one stop input. This mode of operation is
typically used to rapidly provide numerous roughness measurements on large surfaces such as mill rolls or
sheets. All data points can be saved or displayed as they are being taken at a rate of approximately 10 readings
per second. The second mode of operation is for measuring individual parts being presented to the gage, such
as parts on a conveyor. In this mode the few measurements made between a start input and a stop would
typically be averaged and only the single average of that part is saved and/or displayed; one average point for
each start and stop input received.
