DAkkS certificate

Calibrated measuring instruments require calibrated testing equipment.
  • For scales these are calibrated test weights, also known as "Normal".
  • Test weights must be recalibrated periodically depending on frequency of use. This will ensure that they can withstand the demands of a reliable functioning test equipment.
  • Recalibration time depends of the frequency of use, the conditions of use and your needs in terms of security.
  • The standard specifies no particular recalibration interval. We recommend to recalibrate your test weights with intensive use every 12 months and every 6 months with normal use.
