MQB-Meter-Qualification-Board

Meter Qualification Board (MQB) for Functional Meter Validation

Multi-position testing platform for AMI meter qualification, validation, and communication testing

The TESCO Meter Qualification Board (MQB) enables utilities to power, load, and test multiple electric meters simultaneously for functionality, communication, and firmware validation prior to deployment.

MQBs are designed to support AMI meter qualification and certification processes by providing a controlled environment for validating meter performance. By applying load and simulating real-world electrical conditions, the MQB allows utilities to verify meter functionality, communication, and configuration before meters are installed in the field.

Available in multiple configurations, MQBs can be banked together to support multi-position testing, allowing utilities to efficiently test multiple meters simultaneously within a single system.

Applications

The MQB is ideal for:

  • Meter Qualification & Certification
    Validate meter performance prior to deployment in AMI systems
  • Firmware & Configuration Verification
    Ensure correct firmware versions and predefined settings across meter populations
  • Communication Testing
    Verify connectivity and communication functionality of AMI meters
  • Disconnect Testing
    Test remote disconnect/reconnect functionality and confirm operational state
  • Batch Testing for Deployment Readiness
    Test multiple meters simultaneously to improve efficiency and reduce deployment risk

What Makes the MQB Different

The MQB is designed for utilities that need reliable functional validation without the complexity of full multi-phase testing or accuracy calibration systems.

By focusing on:

  • Functional performance
  • Communications validation
  • Operational behavior

The MQB provides a cost-effective and efficient solution for verifying meter readiness before deployment.

FAQs

A meter qualification board is used to verify that an electric meter is functioning correctly, including communications, firmware, and operational behavior.

No. The MQB does not include a reference standard and is not designed for revenue-grade accuracy testing.

The MQB is designed for functional validation, where full phase simulation is not required. This simplifies the system while still allowing verification of meter operation.

Yes. The MQB supports AMI meter validation, including communications, firmware, and disconnect functionality.

The MQB is best used when basic functional validation is required, and full multi-phase testing is not necessary.
