Point-to-Point Mode (Model ALGR)
Similar to the Sweep Setup mode, the Point-To-Point Mode allows
you to create a laser "chalk line", sweeping between any two
positions you specify.
Use the left SELECT button to enter the "PTP: SET PT A" option,
and use the SELECT buttons to rotate the position of the start point
clockwise or counterclockwise. Press the MODE button to enter
the "PTP: SET PT B" option, and use the SELECT buttons to rotate
the position of the end point clockwise or counterclockwise. Press
the MODE button to begin the sweeping action between the two
points. You may use the SELECT buttons to readjust the position of
each point if needed.
N N O O T T E E : In Sweep or Point-to-Point Mode, the selected sweep area will not be exact. The laser will
vary slightly from the selected points.
Spot Mode (Models ALHV, ALHV-G, ALGR)
Spot Mode creates a motionless laser dot for reference, allowing the instrument to be used as a
straight-line laser.
model ALHV,ALHV-G
Press the (E) button until the instrument is in Spot Mode. Press the (F) or (G) to rotate the laser
head clockwise or counter-clockwise. Pressing and holding the (G) or (F) button moves the rotating
beam more quickly.
model ALGR
Use the SELECT buttons to rotate the position of the dot
clockwise or counterclockwise.
Re-Leveling (Models ALH, ALHV,)
If the instrument is bumped or moved, the instrument will automatically attempt to re-level itself.
On a job site, it may be necessary to prevent re-leveling in order to prevent inaccurate
measurements by the operator. The Anti-Drift System (ADS) is used for this purpose (see Anti-Drift
System - ADS). The instrument can also be placed in Manual Mode to allow the instrument to
continue operating when out of level.
Axis Drive Error (Models ALH, ALHV,)
If the instrument is set up or tipped beyond its self-leveling range of ±5°, the laser head will initially
attempt to level; however, when the self-leveling limit is reached, an error will indicate an axis
error (Fig. 8).
Turn the instrument OFF, move the instrument to a more level position, then turn the instrument
on again.
