Calibration Certificate DKD documentation of measured characteristics of balances or test weights and of traceability to the national standard. Additional price.
Calibration of measuring equipment determination of the precision of a measure value without intervention in the measurement system. Example: to check a balance you load a test weight upon it. The term "Calibrating" was formerly also used for adjusting.
Calibration or verification DKD calibration can be carried out on any balance which is in perfect working order. DKD calibration is a private service controlled by the state for ensuring high quality requirements according to DIN EN ISO 9000ff and other standards, e. g. in production and research.
Verification can only be carried out on type-approved balances which carry the green M
Verification
Capacity display a bar lights up to shop the currently selected and optionally available weighing range
Certificate Written confirmation that a service has been provided in accordance with a defined requirement.
Amongst other things, this can be a metrological statement as well as an ISO factory certificate, or any another lasting endorsement.
In the field of verification you receive a verification certificate and a calibration certificate in the DKD/DAkkS.
Certification Confirmation of the achievement or compliance of a predetermined standard, such as a DIN standard such as DIN EN ISO 9000 ff. (Quality management) or DIN EN ISO/IEC 17025 (Accreditation), or a build-type approval for balances.
Commercial error limits See reverification of balances and weights
Conformity declaration from the manufacturer The manufacturer declares that the product fulfils the applicable EU directives. With electronic balances this is always in conjunction with the CE mark.
Conformity evaluation Procedure for confirming warranted characteristics in accordance with recognised rules. For balances this relates to verification.
Control of measuring equipment in the QM system in conjunction with quality standards An organisation certified to a quality standard such as DIN EN ISO 9000 ff. e. g. a production plant is obliged to adhere to a defined quality standard within the framework of its quality management system. To do this, it is imperative that you have measuring equipment which is working accurately.
DIN EN ISO 9001, December Edition 2008 states in section 7.6 "Guidance of monitoring and measuring equipment", that measuring equipment must be calibrated at defined intervals and before use. The measuring devices and measuring standards needed to do this must:
  • be traced back to international or national standards.
  • their measuring uncertainty must be known
  • they must be marked with a clear identification
  • the test must be documented
The DKD calibration fulfils all these requirements.
Counting of single pieces Determining a quantity by weighing. This is possible if the pieces to be counted are roughly the same weight. To do this, you establish a reference weight and then you can weigh the pieces to be counted. Counting balances display the weighed pieces as number of items immediately.
All counting balances can be switched from counting to weighing mode.
Counting resolution The counting resolution is calculated in points from the ratio of the weighing range [Max] divided by the smallest part weight. It is a statement of counting accuracy.
