The vibrometer is switched on by turning the key switch on the front of the
controller to position I. The L ED POWER above the key switch then lights up
and shows that the controller is ready to operate.

The sensor head is equipped with a beam shutter. This can be used to block
the laser beam without switching off the laser, thus keeping the system at a
thermal equilibrium.
2)9  The rotary knob for the beam shutter is on the back of the sensor head and is
labeled EMISSION ON/OFF. To block the laser beam, turn the knob clock-
wise until the red mark points at OFF.
The emission indicator is the L ED LASER on the right of the rotary knob. The
L ED is lit when the laser is active (key switch on the front of the controller in
position I). The L ED is lit regardless of whether the beam shutter is open or
closed.
2)9   The key for the beam shutter is on the front of the sensor head and is labeled
LASER. When the controller is switched on, the beam shutter is automatically
closed. To open the beam shutter, press the LASER key. To close the beam
shutter again press the LASER key a second time.
The emission indicators are two L ED s STANDBY and ON next to the shutter
key. The L ED STANDBY lights up when the controller is switched on. This then
shows that the laser is active but the laser beam is not emitted yet as the
beam shutter is still closed. When the beam shutter key LASER is pressed,
the L ED STANDBY goes out and the L ED ON lights up. This then shows that
the laser beam is being emitted.

To position the sensor head, switch the beam shutter to the OFF position. Only when the
sensor head is roughly in place and has been fixed in a stable position, switch the beam
shutter to ON!
