3-Point Buck-In Procedure Using One Target
Setting up the Equipment
1.
Position and secure the laser.
Position the laser as shown and turn the lever on the magnetic base to ON to lock it securely to the
metal surface.
2.
Coarse level the laser.
Power on the laser and use the speed control knob on the control panel slow the scanner spin until you
can see the laser beam pass over the target (the farther away the target is located, the slower the
scanner must spin). Turn the light switch for the bubble level vials ON. Using the adjustment knobs
and observing the position of the precision level vials, coarse-level the laser so that the laser plane is
approximately parallel to the surface.
3.
Position and secure the target.
Place the target in the
Near Position
(
1
– see Figure 17). Move the target in its magnetic base until the
laser beam roughly hits the mid-position of the target and turn the lever on the magnetic base to ON
to lock it securely to the metal surface.
Note:
As you move the target to the Near Position (1), Far Position A (2) and Far Position B (3),
mark where the base of the target sits on the surface so that it may be repositioned in the same place
each time.
4.
Set the readout.
If you are using the A-1519 or A-1520 Wireless
Targets with the R-1356-2.4ZB PDA Readout or
with Hamar Laser’s alignment programs, set the
readout display through the software.
You may also
need to adjust the sampling rate to dampen the effects
of atmospheric turbulence in the Read15 software (or
in the Hamar Laser alignment program you are using).
Performing the 3-Point Buck-In Using One
Target
1.
Center the target in the Near Position.
With the target in the Near Position, zero the target
on the PDA (see the Read15, Plane5 or Machine
Tool Geo Manuals).
2.
Move the target to Far Position A and tilt PRY
Base
Roll Axis
until the readout reads zero.
With the target in Far Position A, tilt the
Roll Axis
of
laser’s
PRY Base using the adjustment knobs
until the readout reads zero. Be sure to use
only
the
Roll Axis
adjustment knobs (in the setup
displayed above, this would be the adjustment knob marked Roll).
Note:
When the target is in the Near Position, always use the appropriate zero function in the
software. When the target is in the Far Position, always use the laser adjustment knobs to tilt the
laser beam. This is easily remembered by the phrase, “Zero Near, Tilt Far.”
3.
Repeat Steps 1 and 2 until the readout reads zero at both locations.
Continue to move the target between the
Near Position
and
Far Position A
, zeroing the target at the
Near Position
and tilting the laser plane using the
Roll Axis
adjustment knobs at the
Far Position A
until the readout reads zero at both locations.
