Accept Readings key
Use the Accept Readings key, when the laser head positions and data are as desired,
to store the data. The number of samples, displayed in the center of the screen, will
increment by one (180 max). Each time a data point is stored and the laser heads
are rotated to a new position, a thinner line is left behind to denote where data was
acquired.
Note
A minimum of 3 data points over a 45
°
sweep arc are required, but
Emerson recommends a minimum of 8 data points (samples)
acquired over a sweep arc of at least 90
°
.
Note
For the greatest accuracy and repeatability, all readings should be
acquired using the same direction of rotation. In addition, it is best to
use the same direction of rotation as the machine normally operates.
Although the 8215/8225 laser fixtures are designed to be rotated a full revolution
in two seconds - a smooth, uniform acceleration and deceleration during the rota-
tion of the laser heads is necessary for accurate, reliable, and repeatable data collec-
tion.
Caution!
To prevent damage to the laser heads, make sure the antennas do not come into
contact with obstacles (e.g. the ground or base plate) as they are being rotated.
Also, when performing an uncoupled alignment and the laser heads are
mounted in close proximity to each other, make sure the antennas do not come
into contact with each other as one laser head is rotated past the other.
Clear key
Use the Clear key to clear the displayed data average, when the Laser Mode is set to
Averaging. When the Laser Mode is set to Standard, this key is not available.
