In July 2015 the German Weights & Measures encountered a bug in the Legal for Trade software of our indicator 2100, which we have been supplying since the year 2002. It turns out that after a zero calibration the Audit Trail Number is not automatically changed, although this is required. Theoretically this makes it possible to extend the defined weighing capacity, by doing zero calibrations instead of tare-ing out the weight of pallets or containers (in practice this would cause repeated “underload” error messages every time the scale is unloaded).
RAVAS has corrected this bug in the latest version of the software for the indicator 2100: software version P7.8 (the previous version, containing the bug, was version P7.3). The software version number is shown in the display of the indicator, during start-up.
On legal for Trade units with indicator 2100 version P7.3 in the field, the electronics board should be exchanged for one with software version P7.8, before doing a periodical re-verification and re-stamping. Weights & Measures officials may refuse to re-stamp a unit with 2100 indicator version P7.3. RAVAS, or a RAVAS representative, will send you a special proposal for replacement of the electronics board of your 2100 Legal for Trade indicator, if you fill out the form.
