Revenue

Revenue
A revenue meter provides, over a defined range of operating conditions, measurements that are
within international and national defined standards and industry-accepted accuracy limits.
It also provides protection against unauthorized alteration of these measured quantities. National
and utility-based standards regulate protection against unauthorized alteration of measured
quantities.

Revenue metering components

To meet government regulations and utility security requirements, the meter incorporates three
types of security systems:
• Traditional anti-tamper mechanical seals on the meter. See your device installation guide.
• Passcode entry to reset meter values, for example, Master reset.
• Hardware locking mechanism that prevents modification of revenue quantities after they are
locked.

Revenue firmware security features

Your revenue meter has additional firmware security features:
• Your firmware upgrades are recorded in your meter's upgrade log. Contact Technical Support
for information on upgrade log retrieval.
• When revenue-locked, you cannot perform resets, configure some revenue-specific
parameters, or upgrade your meter.

Protected features and settings

Your revenue meter has features and settings that cannot be changed while revenue-locked.
In order to prevent changes to revenue-related features, settings and meter data, you can apply
revenue-locking after all revenue-metering setup is complete. See the ION Device Template
Reference, available from www.usa.siemens.com/pds, for a complete listing of revenue-locked
features and settings.

Revenue locking

Revenue locking may be required to help meet government regulations and utility security
requirements.
Revenue locking your meter helps:
• Prevent changes to revenue-related features, settings and meter data.
• Prevent tampering with your meter's voltage and current connections.
• Ensure the validity of revenue data.
See the ION Device Template Reference, available from www.usa.siemens.com/pds, for a
complete listing of revenue-locked features, settings and meter data.
See the meter's catalog pages, available from www.usa.siemens.com/pds, or consult your local
Siemens Industry representative for information about your device, its options and accessories.
