SWITCHING GRADES LINES.
(1)
If CUT/FILL mode is being used, DEADBAND
alarm and HI/LO/On-Grade LED cluster (in upper
right corner of display) can be connected to solid
finished-grade line or dotted bedding-layer line.
Symbol shown indicates which grade line is
operating. Use Up and Down (↑↓) buttons to
change operating indicator arrow from one grade
line to other.
(2)
Elevation and reach values shown on Graphic
Display always indicate bucket's cutting edge
elevation, regardless of which grade line is
selected. Bucket's cutting edge is always
referenced to solid finished-grade line at start of
operation. If bucket's cutting edge is moved to
dotted bedding-layer line and rereferenced, grade
and reach values change to bedding-layer line with
respect to same BENCHMARK elevation.
SET MARKERS.
Distance markers can be set so you can rough-measure
distance horizontally or vertically in an excavation.
Undercutting required for a pipe bell is an example of a job
where rough measuring is helpful. If pipe joint is
approximately 6 ft (1.8 m) long and bell protrudes
approximately 8 in. (20.3 cm) below finished grade, markers
should be spaced approximately 6 ft (1.8 m) apart. These
markers show that each time bucket's cutting edge comes to a
marker, it is time to undercut for pipe bell. These markers
also provide a visual view measurement instead of numbers
in lower corner of Graphic Display.
