Safety precautions
Easy-Laser®is a laser instrument in laser class 2
with an output power normally less than 1 mW, which
requires the following safety precautions:
• Never stare directly into the laser beam
• Never aim the laser beam at anyone else’s eyes.
Note!
Opening the laser units can result in hazardous radiation, and will invalidate the
manufacturer warranty.
If starting the machine to be measured would result in injuries, the possibility to un-
intentionally start it must be disabled before mounting the equipment, for example by
locking the switch in the o position or removing the fuses. These safety precautions
should remain in place until the measurement equipment has been removed from the

Preparations
Check the environment
• Check that the turbine has a uniform temperature. Mainly important if the turbine
partly has been exposed to direct sunshine.
• Check that the laser, detector and brackets are covered from direct sunlight from
roof windows or other sources. Direct light (sun, strong lights or welding) into the
sensor may result in uctuating measurements and has to be prevented.
• Check that the ambient temperature is within the operating range of the EasyLa-
ser: 0 to 50 degrees.
• Check that airow or wind does not enter the measurement area, especially not
close to the laser source. To further reduce inuence, use appropriate lter set-
tings.
• Check for vibrations, low and mid frequencies, that may interfere with the mea-
surement. If found, identify the source and take actions to reduce the vibrations. In
case vibrations re-mains, use measurement lter (see the user manual).
• Check that rain can not enter into the measurement area
• Refrain from using mobile phone or communication radio while taking a reading.
• Clean all measurement points for oil, grease and other substances using grease
cleaner
• Remove any burr, welding spatter etc. Ensure that no original material is removed
during cleaning.
It is highly recommended that nal measurement is done during the night time when
there is less interfering work ongoing and the temperature has become stable (around
midnight).
Mount the laser transmitter
The laser should be placed on a stable and rigid place, free from air ow, vibrations
and sunshine. A welded structure xed to the ground or the turning gear bearing may
be suitable locations.
Check the following:
• Magnets are seated a machined surface, without tension.
• All magnets have full contact with the surface. If not, release and tighten screws.
• All screws on the bracket are properly tightened (but do not overtighten).
• Make sure that the laser transmitter battery is replaced to avoid interrupting the
measurement.
Note!
The ne adjustment screw on the tilting table must not exceed its maximum position.
That might damage the threads of the screw. See also Techdata in Manual.

12
E960 turbine
Rough align laser beam
The visual targets are used for laser beam prealignment and should be placed at the
rst and last bearing seating.
Part no. 12-0443
1. Place the ruler at the bearing pocket and move the adjustable side to t
the diameter.
2. Read the diameter and divide by two.
3. Switch on the laser.
4. Adjust the laser beam to the far target center. Use the angular adjustment screws
on the laser transmitter.
5. Adjust the laser beam to the target close to the laser. Adjust beam using the oset
adjustments.
6. Repeat until beam passes both target centers as accurate as possible. The laser
bracket may have to be moved if the parallel oset adjustment screws reach the
limit.
7. Remove targets.

13
E960 turbine
Align the laser beam
If extra high accuracy is required, for example during a nal inspection, the beam may
be precisely aligned to the reference surfaces. Note, this is not necessary during normal
corrective adjustment work.
Reference target
The purpose of a reference target is to monitor that the laser beam remain in its origi-
nal position during the measurement within the specied tolerance. Reasons for devia-
tion may be temperature changes, sun light or someone touching the laser.
1. Place the reference target at the far end of the turbine.
2. Select and to display the reference target.
3. The rst time you select the command, a window is displayed. Select which detec-
tor you want to use as reference detector and press OK.
Function buttons

1. Place the detector at the reference point furthest
away from the laser transmitter.
2. Turn the detector to position 9 o’clock position and
select .
3. Turn detector to 3 o’clock and select .
4. Adjust horizontal error to zero with the angular
adjustment screw.
5. Turn detector to 6 o’clock and adjust
vertical error to zero.
6. Move the detector close to the laser transmitter and
repeat step 2-5 to adjust the oset.
Repeat until both reference points are zero.

E960 turbine
Adjust the measuring probe
1. Place the detector in the measurement position.
2. Adjust the probe length to the radius.
3. Turn the probe to position 6.
4. Adjust the detector vertically and horizontally to the centre of the laser beam.
5. Adjust the detector xture so that the probe runs parallel to the surface to be mea-
sured.
The measuring principle is the same for both long and short
stroke bracket. The probe rod is very easily adapted to each
diameter with extensions of different length.
Before measuring, please check that you have mounted the bracket and probe correctly.
If the bracket has been mounted skewed, the values will be incorrect. Image below show
a linebore measurement, but the same principle apply to turbines.
Make sure it is the same distance
Green line = correct
Red dotted line = incorrect

15
E960 turbine
Measure
You can use the program Half circle or Multi-
points. Here the program Half circle is used.
Please note that the order of measurement or
distances is not dependent on laser position.
First measurement point may therefore be the
most distant from the laser.
Note!
Face the laser transmitter from the detector. Then 9 o’clock is to the left, as in
the measuring programs.
The measurement probe at 9 o’clock. The measurement probe at 3 o’clock. The measurement probe at 6 o’clock.
