SQUARE (Fig. E)
Place the SP5 on the floor or a fairly level surface near the walls or the
objects to be squared. Measure from one wall to the laser beam at two
points. One point near the SP5 and at another point farther away. (Note: the
greater the distance between the two points the greater the possible accu-
racy). Rotate the SP5 until the two measurements are equal. Do not move the
SP5 until the rest of the measuring is completed. Now take two measure-
ments from the other wall to that laser beam. If the measurements of these
two points are the same, then the walls are square. If they are not equal,
move the second wall until the two measurements are equal.
You can also square vertical surfaces to horizontal surfaces by using a
plumb beam and a level beam.
LEVEL (Fig. F)
Set the SP5 on a surface that is at a convenient height for marking a level
reference plane on walls or other surfaces. Mark the laser dot's location. You
can now turn the SP5 to move the laser dot to another location and continue
marking. These marks can be connected together with a straight edge to
give you a level line.
Be careful not to change the height of the SP5 during the process or your
level line will vary in height.
For damages caused by usage other then intended, the user is responsible.
INSERTING/REPLACING THE BATTERIES
Remove the Universal Mount if mounted. Remove the battery cover from the
battery compartment located in the bottom of the instrument itself.
Insert the batteries or replace the used batteries with new ones.
Check for correct polarity.
Do not use rechargeable batteries!
Extreme temperatures and the use of batteries with different levels of charge
can reduce the operating time of the instrument.
