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 to the tolerance band compared to previous calibrations
Therefore, the interval between verifications of calibration 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 one year.

You should regularly inspect the rollers to assure that they are running easily and smooth-
ly. You can replace the rollers yourself, as necessary. Please indicate the tension meter
model and the serial number (given on the rear side of the tension meter) in your spare-
parts order.
For example:

5.1 Rollers
The tension meter is easy to maintain.
Depending on operating time and load, the instrument should be checked according to the
locally valid regulations and conditions (as described in Chapter 3.6.2). The use of other
test methods than the procedure described in Chapter 3.6.2 may cause deviating measu-
ring results.
