MQB-Meter-Qualification-Board

Meter Qualification Board (MQB) for Functional Meter Validation

The TESCO MQB Meter Qualification Board is designed to perform functional validation of electric meters, ensuring proper operation, communications, firmware integrity, and disconnect performance prior to deployment.

The MQB applies voltage and current on Phase A only, providing a cost-effective solution for utilities that need to verify meter functionality without requiring full multi-phase simulation or revenue-grade accuracy testing.

What is the MQB Used For?

The MQB is used to confirm that meters are:

  • Operating correctly
  • Communicating properly
  • Configured with the correct firmware and settings
  • Responding to disconnect and control commands

Unlike meter test boards, the MQB does not perform accuracy calibration. It is designed to ensure the meter is functionally sound and ready for service.

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.
