4 Service and Maintenance
The tension meter is easy to maintain.Depending on operating time and load, the tension
meter should be checked according to the locally valid regulations and conditions
(as described in Chapter 3.4).
Other testing methods as described in chapter 3.4 can cause different measuring
readings.
You should regularly inspect the rollers to assure that they are running easily and
smoothly. You can replace the rollers yourself, as necessary. When ordering spare rollers,
please indicate the tension meter model and the serial number (on the rear side of the ten-
sion meter).
e. g.

4.2 Cleaning
For cleaning the unit, do not use any
AGGRESSIVE SOLVENTS
such as trichloroethylene or similar chemicals.
NO WARRANTY OR LIABILITY
shall be accepted for damage resulting from improper cleaning.
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.
Assuming normal operating time and load as well as careful handling of the tension meter,
we recommend a verification interval of 1 year.
