Split Prism Vial Assembly:
≤
.00006 in/ft (0.005 mm/m)
Standard Levels:
≤
.00012 in /ft (0.01 mm/m)
Example:
15 ft. (D1)
.000 (Near Reading)
.035 (Far Reading 1)
+ .010 (Far Reading 2)
.045 (Sum of the two readings)
+.045 / 2 = +.0225 (Set Point)
Calibration = Set Point / D1
.0225 / 15 = .0015 inches/ft. (out of spec)
If this value is out of the specification, then you will need to use the Set Point to bring it back into
specification. See Step 6 below.
Setting the First Level Vial – Pitch Axis
6. Tilt the laser to the Set Point
Move the target back to the Near
Point to verify it still reads zero. If
not, re-zero it. Then move the target
back to the Far Point and tilt the
laser by adjusting the Pitch Axis
adjustment knob on the laser base
until the readout displays the
calculated Set Point.
7. Adjust the level.
Locate the two recessed adjustment
screws for the Pitch Axis level you
are adjusting). Using the wrench
provided, adjust the level assembly
until the bubble is centered in the
window for the Standard Level vials
or the two halves of the bubbles line
up for the Split Prism Level vial (see
Figure 4 and Figure 5). For
example, to move the bubble to the
left, loosen the left screw and
tighten the right screw. When the bubble is centered, tighten the left screw until the bubble is
stationary. Check your work by repeating these steps and ensuring that the level is calibrated to within
the specified tolerances.
Note:
Tighten the set screws just firmly enough to hold the window assembly in place. Over-
tightening these screws may cause damage.
Checking the Levels for Accuracy
To check for accuracy, repeat the steps for setting the precision level vials. The Set Point should be the
same as the previous Set Point. If not, calculate a new set point and adjust as necessary.
