9410 series Revenue metering
Revenue metering
Revenue metering overview
Revenue metering is one of your device’s primary features.
The main purpose of a revenue meter is to provide measurements that are within
industry-accepted limits for accuracy over a defined range of operating conditions. It
also provides adequate protection against unauthorized alteration of these measured
quantities. International and national standards define industry accepted accuracy
limits. National and utility-based standards regulate protection against unauthorized
alteration of measured quantities.
Components of revenue metering
To meet government regulations and utility security requirements, the meter
incorporates three types of security systems.
The three types of security systems are:
• traditional anti-tamper mechanical seals on the meter
• a password-based security system for resetting meter values (for example, Peak
Demand reset)
• a hardware-based security system that prevents modification of revenue
quantities after the meter is locked
Refer to the installation guide shipped with your meter and accessories regarding the
installation of these security features.
Revenue firmware security features
Your revenue-specific meter has additional firmware security features.
• You can only upgrade to revenue-qualified firmware and frameworks.
• Your firmware upgrades are recorded in your meter’s event log. An additional
firmware upgrade log is stored on your meter. Contact technical support for
information on upgrade log retrieval
• You cannot perform resets or configure some revenue-specific parameters on
your meter while it is revenue-locked.
Protected features and settings
Your meter has features and settings that cannot be changed while the meter is
revenue-locked.
In order to prevent modifications to revenue-related settings and data on your meter,
some of the features and parameters on your meter cannot be edited once the meter is
revenue-locked. For a complete listing of revenue-locked features and settings,
download the ION Device Template Reference, available from
www.usa.siemens.com/pds
Revenue meter pre-installation procedure
You must configure and revenue lock your meter before installation.
