Examination of findings
With a service testing is officially ascertained whether a calibrated measuring device ( water meters , electricity meters , gas meters , heat meters ), the maximum errors permitted in accordance with the Weights and Measures Act complies.
For each measuring device in question, an application for a diagnostic test can be submitted to a state-approved test center or the calibration office . For a processing fee, you can get a test certificate on which it is noted whether the measuring device complies with the traffic error limits or not. If the traffic error limits are exceeded, the determined measurement error is also entered.
When checking the findings, the measuring device is first examined externally for damage, then checked individually for different loads and then dismantled for internal examination. In addition, it is checked whether it complies with the approval regulations and whether the stamps ( seals ) are not damaged.
