Meter Test Board (MTB1)
TESCO’s MTB1 is a full series-parallel, multi-position test board designed for advanced accuracy testing, AMI/AMR validation, and functional meter diagnostics. It provides meter shops with a complete platform for software and firmware verification, communication troubleshooting, and long-duration load simulations—including dropped cycle, phasor distortion, and harmonic waveform testing. The MTB1 supports a wide range of meter forms, and its automated features and integrated reference standard help streamline testing, improve repeatability, and reduce manual setup time.
For utilities and meter manufacturers looking to verify performance under real-world conditions, the MTB1 offers unmatched flexibility and precision.
