2. Fine Angular Adjustment
Indicator – a tool has been provided
to fit between the Fine Adjustment
Knobs and the brass nut. This tool
acts as a gage to show you how far to
tighten the knobs to the center of
their adjustment range. Slide the tool
between the black Fine Adjustment
Knob and the brass nut and tighten
the knobs until they touch the tool.
Then loosen the knobs just enough so
you can remove the tool. The Fine Adjustment Knobs are now in the center of their range.
Adjusting the L-708 Laser
In a typical bore measuring application, the L-708 Laser is mounted concentric to one end of the bore by
means of a bore adapter. The L-708 laser beam is concentric to its 1.2495 in. (31.74 mm) OD mounting
surface to .0003 in. (0.008 mm) and the face of the laser has powerful magnets to hold the laser in the
adapter. Because fixtures are seldom perfect, the laser beam requires angular adjustments to make it
concentric to the bore. This is accomplished by placing the self-centering measuring target at the other
end of the bore and adjusting the angular adjustment knobs to set/tilt the laser to zero on the target,
establishing a reference bore centerline.
Pulse/Continuous Modes for the L-708 Laser
The L-708 Laser is equipped with a PULSE/CONTinuous switch, which manually switches the laser
beam between
Pulsed
and
Fixed Beam Modes
.
Pulse Mode
automatically removes the effects of excess
(ambient) background light for the R-1307 readouts, providing a more accurate reading. The R-1307C, R-
1307-900/2.4 and R-1307-2.4ZB support Pulse Mode when used with their respective interfaces. See the
R-1307 Operations Manual for further information.
Attaching the Battery Pack
The L-708 Laser battery pack is a stand-alone unit
that attaches magnetically. The battery pack has a
detachable cord with a probe at each end. One
probe attaches directly to a jack on the battery pack
and the other is inserted in the control panel of the
L-708 Laser.
1. Turn off the main power switch.
The main power switch must be off before
attaching the battery pack.
2. Insert the probe into the battery power input jack.
The jack is located on the end panel of the battery pack. Insert
the probe gently until it snaps into place.
3. Insert the probe into the laser power input jack.
The jack is located on the micrometer control, at the apex of the V and H axis arrows. Insert the
probe gently until it snaps into place.
