Spectra Precision LL500 Laser Level - Manual

Rugged, Reliable Laser
Leveling Systems
Setting the Industry Standard
Accurate, stable and very reliable, the Spectra
Precision
® Laser LL500 is the ideal one-person
leveling system for a range of everyday elevation
measurements on the construction site.
Designed for use on the jobsite, and reliable
even in the harshest of conditions, today more
contractors around the world use Spectra
Precision Lasers to increase productivity and
profitability.
One Laser Levels Your Entire Work Area
The LL500 transmitter sends a continuous, self-
leveled 360-degree laser reference over a work
area, up to a 500-meter (1,600-foot) diameter.
With the LL500, you can perform any two-person
leveling task with just one person. Simply set up
the laser transmitter anywhere on your job site;
it transmits a laser beam to provide an elevation
reference that can be picked up by one or more
laser receivers, including our innovative HL700 or
CR600, whether they are handheld, attached to a
grade rod or mounted on a machine.
LL500 Benefits
• Temperature compensation allows you to meet
your toughest accuracy requirements in any type
of variable environmental conditions.
• Reduces the amount of time required for each
grade shot, so more grade shots are taken for
increased accuracy.
• Eliminates rework caused by miscommunication
or out-of-level instruments with built-in out-of-
level warning and shut-off.
• Immediately locates the laser plane with the
visible spotting beam.
HL700 Laserometer
The Spectra Precision Laser HL700 Laserometer
uses new technology to measure and display
beam location and is ideal for use with the LL500
transmitter. The HL700 features a digital readout of
elevation that shows exactly how far you are from
on-grade allowing quick elevation checks without
moving the rod clamp. An anti-strobe sensor stops
construction lights from setting off the receiver,
and makes it easier to identify true laser beam
signals. The protective over molded housing
withstands a drop of 3 m (10 ft) onto concrete. The
highly visible LED display and dual sided LCD’s
allow you to work anywhere.
CR600 Receiver
Another receiver option is the Spectra Precision
Laser CR600. In addition to handheld and rod
mounted capabilities, the CR600 can be used as
a machine-mounted receiver with 270-degree
reception and a highly visible display for use on a
backhoe, small excavator or skid steer. Improving
accuracy, safety and efficiency, the CR600 delivers
grade information to the operator right in the cab.
