Traverse Unit
The top panel of the traverse unit carries a membrane type control panel and a liquid crystal
display. The unit houses the electronics for controlling the measurement sequence, computing
the mea-
surement data and outputting the results to the display, or to the
RS232 port for use with a printer (when included) or to a com-
puter, for further analysis.
The unit also contains a drive motor which traverses the pickup
across the surface to be measured. The measuring stroke always starts from the extreme
outward position. At the end of the measurement the pickup returns to this position ready for
the next
measurement. The traverse length is determined from selections of cut-off or length.
