Figure 7 Manual Calibration 

Suggestion:

 

Manual  white  calibration  and  black  calibration  are 

only  needed  under  the  condit ion  that  the  instrument  has  been 
used for a lo ng time and the measured data are  not accurate.  

 

4.  Changing Measuring Aperture 

 

Note:  After  changing  the  measuring  aperture,  you  have   to  enter 
the  “Settings   –Aperture   Setting ”  to  select  the  corresponding 
aperture . Or it may lead to the inaccurate measured data.  

 

NH310 colorimeter can be configured with three measuring apertures: 

Φ8mm measuring aperture, Φ4mm measuring aperture and extended

 

Φ8mm 

measuring  aperture  (optional).  The  users  can  change  it  for 

different needs.
