Recalibration
DKD certificate - Certificates:
We recommend that the instrument is regularly recalibrated by the manufacturer, with time
intervals of approx. 12 months. Every factory recalibration includes, additionally, an extensive free-
of-charge check of all system parameters with respect to their compliance with the specification.
The basic settings will be corrected if necessary.
