These Operating Instructions refer to Model DN1 of the DN Series.

The individual models of the DN Series are also available with the

following modifications (customized versions):

-  Special tension ranges

-  Customized measuring head width for applications with limited access  

  space

-  Customized distance between the two outer guide rollers to minimize 

  deflection of the material

-  Calibration for material path other than standard (vertical)

-  Calibration to different units of measure, such as g or kg

2.1  Specifications

*  Depending on model, either width of filament guide or outer distance between outside
  guide rollers. 
** Suitable for 95% of applications. PA = Polyamide Monofilament
  If the material to be measured differs significant from the SCHMIDT calibration  
  material in diameter, rigidity, shape, etc., we recommend calibration using custom- 
  er material. For this purpose, a material sample of about 5 m should be supplied.
  International unit for tension force: 1 cN  = 1.02 g  =  0.01 N
   

1 daN  = 1.02 kg  = 10.0 N
