A. The Turbine Tools coupling alignment procedures
work well with metric units.
Rim and Face coupling alignment
Multiple Rotor Rim and Face coupling
Reverse coupling alignment
any units may be used as long as the relationship between Dial Indicator readings and Distance readings is 1000 to 1.
Distance readings would include coupling diameter and distances to bearings.
Dial readings are entered as mils (thousandths of an inch).
are entered as inches.
One inch equals one thousand mils.
The calculated values are displayed as mils.
Dial readings are entered as micro meters
(microns), (thousandths of a millimeter).
Distances are entered as as millimeters.
One millimeter equals one
thousand micro meters.
The calculated values are displayed as micro meters.

values are displayed as millimeters.
These units work well when the amount of misalignment read on the dial indicators
is large or greater than 1 millimeter (1000 micro meters).
The tight wire procedures use metric units with a couple of notes.
Units used should be consistent.
Wire readings can be entered as micro meters or millimeters.
results will then be displayed as micro meters or millimeters.
1. The wire Sag is automatically calculated and displayed in mils.
This can be overridden by
simply entering a value in micro meters (or millimeters) into the Sag data box.
2. Since the Sag calculation is overridden and not used, the values for the Weight and Wire
diameter may be left blank or left at 30 pounds and .016 inch as these values are only needed for the Sag calculation.
3. To use the Offset wire alignment, the distance at each
location must be entered in feet and inches. However if the wire set points are set to the exact desired set point
readings, then there is no need to use the Offset alignment and the distances may simply be left blank.
