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). The use of other test methods than the procedure described
in Chapter 3.4 may cause deviating measuring results.
4.1 Rollers
You should regularly inspect the rollers to assure that they are running easily and
smoothly. You can replace the rollers yourself, as necessary. In such a case, please indi-
cate the tension meter model and the serial number (given on the rear side of the tension
meter) in your spareparts order.
For example:
Order of spare rollers
:
Model:
ZF2-12
(on the rear of the tension meter)
Serial number: 211 - 888888
(on the rear of the tension meter)
Standard rollers: Order number R521105
Supply:
1 set (3 pieces) spare rollers 900 m/min with mounting wrench
or
Model:

(on the rear of the tension meter)
Serial number: Z 211 - 888888 (on the rear of the tension meter)
Roller Code

5 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.
6 Verification Intervals
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.
