1.3.2 Measurement Security and Firmware Downloads (WELMEC 7.2 Extension D)
The OMNI 4000 and 7000 models have 16 password-protected access levels for protecting
configuration parameters and for firmware downloads. When software sealing for parameters and
firmware is applied, the highest level is reserved for Weights and Measures Agents and other
agencies that act in the same way. Through software sealing, all communication ports can be set
to “read-only.”
Only licensed firmware files can be transmitted.
This method of firmware transmission meets all requirements of WELMEC 7.2 2015 Extension D,
Software Guide—Measuring Instruments Directive.
