3 First Steps
If the functional test has been successful you can now make measurements
as described in
chapter 4 .
If your vibrometer does not perform as described above, read through the
information on fault diagnosis provided in
chapter 6 and, if necessary, contact
your local Polytec representative.
3.4.2 Vibrometer with Sensor Head OFV-511/-512
For the installation and an initial functional test of the vibrometer, proceed as
follows:
Preparing 1. Only OFV-512: Unscrew the mini sensor from the reference fiber. The
reference fiber is marked with a red dot. Mount the reference head
OFV-151 on the reference fiber as described in
section 5.6 .
2. Deactivate the transport safety mechanism on the back of the sensor
head by turning the screw with the Allen key provided to position
MEASUREMENT (refer to
section 5.8 ).
3. Make sure that the key switch on the controller is in position O.
4. Check the setting on the mains voltage selector on the back of the
controller as well as the fuses.
Cabling 5. Plug the connecting cable into the Sub-D jack SIGNAL PROCESSOR on
the back of the sensor head and into the Sub-D jack INTERFEROMETER
on the back of the controller. Fix the connections with the screws
provided.
All connections must be easy to plug in. If not, check the plug for bent
contact pins to avoid serious damage being incurred.
6. Use the earthed mains cable to connect the controller to a wall outlet
providing protective grounding.
Switching on 7. Switch the controller on by turning the key switch to position I.
On the front of the controller the L
ED
POWER lights up. Providing the
connecting cable has been installed correctly, the L
ED
STANDBY on the
sensor head also lights up. Laser light is not yet emitted as the beam
shutter is still closed.
8. Before now opening the beam shutter, remember the information on laser
safety provided in section 1.1 !
9. Open the beam shutter on the sensor head by pressing the key LASER on
the front of the sensor head.
The L
ED
ON on the sensor head lights up. At the same time the L
ED
STANDBY goes out. The laser beam is now emitted from the mini
sensor.
