•
Measurement and calibration legislation stipulates that a measured value which is
detected on a measurement device that has been verified as legal for trade in an
application requiring official verification and is transmitted to an electronic data
processing system must be documented in a manipulation-proof manner for a period
dating back at least 90 days.
•
Documentation occurs in the alibi memory on the SD card of the SIM2000-2 Prime
controller. The alibi memory must be approved by the Physikalisch-Technische
Bundesanstalt (PTB) or another notified body.
•
The VMS5200-x MID ensures compliance with calibration legislation for measurement
data as well as the traceability of all measurement processes in the measurement
system.
For this purpose, all measured values obtained are stored in a legally compliant
manner in the alibi memory along with their date, time, and a unique consecutive alibi
ID (“identification index”), which together form the legally relevant identifier of a
measurement data record.
The manipulation-proof status of the alibi memory storage was verified as part of an
official WELMEC SW check by the appropriate authority.
