started)

Use the Accept key to accept and store the reading for the active foot. The Enter
key can be used to do the same.
Check Lasers
Use the Check Lasers key to check the operational status of the heads. Refer to the
Check Lasers section on page 3-30 for more information.
Acquiring Alignment Data
To provide data acquisition for varying applications, circumstances, and prefer-
ences, a number of different data collection methods are provided. Therefore, data
acquisition screens vary depending on the alignment method defined for the job.
The method to be used is defined on the Alt Main screen. These methods include:
• Auto Sweep
Data is automatically acquired while the shaft is rotated. The arc of rotation can vary
from as little as 45° to a full 360° (one revolution). This method is especially useful
when the 4 point measurement technique is impractical or when inconsistencies in
shaft position exist at points in the rotation. Averaging mode allows many revolu-
tions. Refer to the Auto Sweep section on page 3-85 for more information.
• Manual Sweep
Data is measured each time the laser heads are in alignment and the number
keypad is pressed. Data from up to 180 positions may be recorded. This method is
especially useful for performing uncoupled or non-rotational alignments or when
too much background vibration is present. This method functions similarly to the
Auto Sweep mode except that the laser heads, or shafts, are stopped at each posi-
tion where data is to be taken and a key pressed to store a reading. Refer to the
Manual Sweep section on page 3-94 for more information.
