Additional Revenue Metering Security
To meet government regulations and utility security requirements, the revenue
meter incorporates additional security systems:
◆ a hardware-locked security system that prevents modification of revenue
quantities after the meter is sealed.
◆ a traditional anti-tamper mechanical seal on the meter base unit.
Hardware Lock Security
The hardware-locked security feature is an ordering option for some ION meters.
This hardware lock is factory set; to make configuration changes to billing
parameters on a hardware-locked meter, you must first place the meter in TEST
mode. Refer to your meter’s User’s Guide for the location of the test mode button.
In all cases, the TEST mode button is located under the anti-tamper sealed outer
cover.
In certain countries the meter is no longer revenue certified if the hardware lock is
broken.
Typical values that are protected include:
◆ kWh, kVARh, kVAh delivered, received, del-rec, del+rec.
◆ kW, kVAR, kVA Thermal and Sliding Window demand min and max values.
◆ Digital Outputs controlling the energy pulsing applications.
◆ All Power system settings, including PT an CT ratios.
