The current laser reading (in mils or mm, depending on the analyzer units) is dis-
played for the selected segment (highlighted with the red box around it). Dashed
lines displayed just under a segment indicate that no data has been accepted for
that segment. Start at the farthest point and center both lasers. The moveable
sensor head should be positioned so that the beam from the stationary head is hor-
izontally centered in the moveable heads target. If it is not within a band ± 40 mils
of the center vertical axis, the error message “Beam horizontally off center” will be
displayed. To remove the message, readjust the moveable sensor head.
Just like the Enter Dimensions screen, the Straightness Data screen will display up
to three measurement locations at one time. If the last segment defined (furthest
from the fixed laser head) is displayed, the reference line will extend no further
than the last laser to indicate that this is the last measurement location for the move-
able laser head defined (as shown above). If the last segment displayed is not the
last measurement location for the moveable laser head defined, the reference line
will extend beyond the last laser head displayed to indicate that more measurement
locations are defined.
A graph representing the overall setup is displayed at the bottom of the screen. The
laser heads for the each of the segments defined, including the fixed laser head are
represented on the graph by miniaturized laser fixtures. The positions (segment
lengths) for each of the laser heads will be to scale. The selected segment is repre-
sented on the graph by a small arrow just below that segment laser head. The refer-
ence line from the location of the fixed laser head is represented on the graph by
a dashed line protruding from the fixed laser head in the direction (indicated by
an arrowhead) of the measurement locations for the moveable laser head. In the
example screen above, a total of six measurement segments have been defined
(represented by miniaturized laser fixtures) and the last segment is selected (repre-
sented by a small arrow just below it).
Check Lasers key
Use the Check Lasers key on the Alt screen to check the operational status of the
heads. Refer to the Check Lasers section on page 3-30 for more information
Accept Reading key
Use the Accept Reading key to accept and store the value displayed.
First key
Use the First key to move to the first segment (closest to the fixed head).
