NIRFlex N-500

 Operation Manual, Version G

•   Disconnect the electric lasers power supply 

plug.

•   Loosen the two screws which are on the laser 

unit bottom plate.  
For easy release of the laser it is recommended 
to lift it upright and than pull the laser unit 
backwards.

•   Now take the new laser unit, insert it and make 

sure that its base plate is correctly placed into 
the bolts.

•   Fix the new laser unit with the two screws and 

connect the electric plug. 

•   Close the housing of the laser unit. This can 

easily be done by first positioning the slits over 
the screws.  
When the instrument and the PC is switched 
on again and the NIRWare Operator is started, 
a corresponding message will be displayed 
and inform you that this change in hardware 
configuration must be added into the data-
base.

Removing the LASER unit

For installation proceed in reverse order.

 

NOTICE

Risk of instrument damage by ingress of particles.
•  Check proper seating of all housing parts before use
•  Do not operate instrument when housing is open or unlocked
