1.2.2 Measurement Security and Firmware Downloads (WELMEC 7.2 Extension D)
The OMNI 4000 and 7000 models have 16 password levels for protecting parameters and
firmware download permission. 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.
