1. SET UP THE FIXTURLASER GO
1.1 Mount the “S” sensor on the stationary shaft.
The sensors may be mounted on the shafts or on
the coupling hubs.
Place the bracket on the shaft and pull the chain
under the shaft and hook it over the pin.
Hand tighten the nut, then ½ turn more with the
wrench.
1.2 Mount the “M” sensor on the movable shaft.
Place the bracket on the shaft and pull the chain
under the shaft and hook it over the pin.
Hand tighten the nut.
Visually align the sensors (side to side), then
tighten the nut ½ turn more with the wrench.
1.3 Connect the cables into either connector on the
display unit.
1.4 Turn the unit on by pressing the red button at the
center bottom of the display.
1.5 The Horizontal Shaft Alignment coupling icon will
be highlighted in black. Press the “OK” button on
the right hand key pad to enter the Horizontal Shaft
Alignment program.
Use the up/down & left/right arrow buttons
on the right hand key pad to move the black
highlight to the different icons as needed. Press
the “OK” button to select.
1.6 Rotate the sensors to 12:00.
1.7 Aim the lasers.
The sensors will be on different elevations.

Clock Method
The built-in guidance of the Tripoint method may not allow you to measure misalignment if the sensors are less than 8" apart
and the shafts cannot rotate more than 90° total. The Tripoint method uses the inclinometer angles to make calculations and
guide you in making the best measurement possible. In contrast, the Clock method only uses the inclinometer for the operator
to reference clock positions. The Clock method bypasses this guidance and allows the user to take readings wherever possible. A
typical use of the Clock method would be on a smaller machine with something obstructing the rotation of the shafts.
The purpose of the clock method is to define the maximum rotation allowed in the first two readings (9 o’clock and 3 o‘clock) and take
the last measurement half-way between those. In the Clock method, measurements are registered at 9 oclock, 3 o'clock and 12 o’clock
– in that order – regardless of where the readings are actually taken. The inclinometers and the display will guide you through the
positions. Remember, it is best to rotate the shafts as much as possible. Rotation of less than 60° may make for a difficult alignment.
The steps below will walk us through a standard Clock method alignment, taking readings at 9 o’clock, 3 o’clock and 12 o’clock.
