Page 9: Material Thickness Compensator
3.2 Material thickness compensator (Only used at instruments with material thickness compensator) The 3-roller system for tension measurement relies on the displacement of the middle roller to give an indication of the line tension. As the material thickness changes, there will be a change in the tension reading, even when the line tension has not changed. -

Page 11: Verification Of The Dn1 Calibration
Any difference in process material size and rigidity from the standard material may cause a deviation of the accuracy. In 95 % of all industrial applications the SCHMIDT calibration has been proven to provide the best results and is used for comparative purposes. -
Page 12: Air Damping (Optional Accessory Code A)
3.5 Air damping (optional accessory Code A) During operation, as in spooling or winding machines, high frequency tension fluctuation can occur. This process fluctuation can result in rapid pointer swings which make it difficult to read the scale. This effect can be reduced by using the built in Air Dashpot Damping mechanism. -
Page 13: Service And Maintenance
The question of finding the right frequency of calibration accuracy verification depends on several different factors: Operating time and load of the SCHMIDT tension meter Tolerance band defined by the customer Changes of the tolerance band compared to previous verifications of calibration Therefore, the interval between verifications must be determined by the user`s Quality Assurance Department based on the user`s experience. -
