Page 3: Warranty And Liability
Warranty: - SCHMIDT tension meters are warranted for 12 months. Parts subject to wear, electronic components and measuring springs are not covered by the warranty. No warranty or liability will be accepted for bodily injury or property damage resulting from one or several of the following causes: - Misuse or abuse of the device. -
Page 4: Informal Safety Measures
The device is intended exclusively to be used as a tension meter. Any other use or any use exceeding this intention will be regarded as misuse. Under no circumstances shall HANS SCHMIDT & Co GmbH be held liable for damage resulting from misuse. -

** 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. -

Page 8: Mounting The Special Finger Support (On The Rear Side Of The Tension Meter)
3.1.1 Mounting the Special Finger Support (on the rear side of the tension meter) Whenever useful and necessary, the tension meter is supplied with a special finger support. We recommend mounting the finger support when measuring high tensions (with Model DX2-1000 and higher tension ranges) to reduce the necessary effort to move the outer rollers with the Thumb piece on the front of the tension meter and facilitate acquisition of the material to be measured. -

3.1.3 Stationary Mounting of Model DX2S Model DX2S (S = stationary) is intended for stationary applications only and therefore features a mounting plate for permanent installation at the measuring location. The mounting plate dimensions are given in figure 3.1.3. Mounting plate 2 Fastening screws M5 2 Holes 5.2 mmØ... -

Page 11: Material Thickness Compensator
3.3 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. -

3.4 Measuring with the Tension Meter Requirement: If necessary, a sample of the material to be measured must be inserted in the thickness compensator as described in Chapter 3.3. Process material Guide rollers Filament guide Guide rollers Measuring roller Thumb piece fig. -
Page 13: Verification Of The Dx2 Calibration
The filament sizes are noted in Chapter 2. 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 14: Air Damping (Optional Accessory Code A)
3.6 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 15: 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. -
