5. Advanced use

5.1 Limited rotation

In some applications, limited space around the shaft coupling forbids the rotation of the
measuring units to the 9 or 3 o'clock position. However, it is still possible to perform the
alignment as long as the measuring units can rotate 180°.
Execute all preparation steps as per chapter 3.1 to 3.6.
Measuring sequence:
1. The display unit indicates that the measuring units should be placed in the 9 o'clock
position. Since you can't reach it, place the measuring units in your start position (in
our example 11 o'clock) and confirm the measurement by pressing the "next"
button: .
2. The display unit now indicates the measuring units should be placed in the 3 o'clock
position. Rotate the measuring units by 180° (in our example to the 5 o'clock position)
and confirm the measurement:
3. You can now complete the alignment following the instructions sequence as per
chapter 3.8.

5.2 Trouble shooting

5.2.1 The system does not switch on

a) Check that batteries are inserted in the right way.
b) Replace the batteries. Use principally Alkaline batteries for a better life span.

5.2.2 No laser lines

a) Make sure that the display unit is switched ON.
b) Check the cables and connectors. Assure that all cables are properly connected.
c) Check to see if the measuring units' warning LEDs flash.
d) Replace the batteries.

5.2.3 No measurement values

a) Check the cables and connectors.
b) Assure that the laser lines hit the positioning detectors.
c) Assure uninterrupted travel of the laser lines.

5.2.4 Fluctuating measurement values

a) Assure tight attachment of fixtures and measuring units.
b) Assure that the laser lines hit the detectors.
c) Assure that air turbulence does not influence the measurement.
d) Assure that direct bright light or obstructed laser lines do not influence the
measurement results.
