5 Service and Maintenance
The tension meter is easy to maintain. Depending on operating time and load, the ten-
sion meter should be checked according to the locally valid regulations and conditions (as
described in Chapter 3.3). The use of other test methods than the procedure described in
Chapter 3.3 may cause deviating measuring results.
6 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.
7 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 hardness tester
 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 hardness
tester, we recommend a verification interval of 1 year.
