Meter Engineering Board 1 (MEB1), Series-Parallel Meter Engineering Board for Advanced Functional and Load Testing
The TESCO MEB1 Meter Engineering Board is a series-parallel, multi-position system designed for advanced functional validation and engineering-level testing of electric meters.
With engineering-grade metrology (~0.1% accuracy), the MEB1 enables utilities to perform load-based testing, demand validation, and comparative analysis across multiple meters—bridging the gap between basic functional testing and full accuracy calibration.
What is a Meter Engineering Board?
A meter engineering board is used to evaluate how electric meters perform under load and over time, including demand behavior, time-of-use operation, and overall meter response.
- Unlike meter qualification boards, MEB systems:
- Include basic metrology (~0.1%)
- Support load-based and comparative testing
- Provide deeper insight into meter performance
Description
Meter Performance Validation Under Load
The MEB1 is designed to evaluate how meters perform under real operating conditions by running tests over time and under varying load levels.
This includes validating:
- Demand calculations
- Time-of-use performance
- Meter response under sustained load conditions
With approximately 0.1% accuracy, the MEB1 provides engineering-level validation to confirm that meter performance is consistent and within expected operating ranges—without requiring revenue-grade calibration.

What Makes the MEB1 Different
The MEB1 is designed for utilities that need to validate how meters behave under load at scale.
By combining:
- Series-parallel architecture
- Multi-position testing
- Engineering-grade metrology (~0.1%)
The MEB1 enables utilities to perform high-throughput performance validation and engineering-level testing before calibration or deployment.
