Main Printed Circuit Board Assembly (PCA)
The 'Error' message is a firmware-level lockout occurring when the microprocessor detects a checksum mismatch in the calibration ROM or a hardware failure in the measurement engine. This failure mode prevents the device from performing its primary function of signal processing and True-RMS calculation. Replacing the main PCA is the only surgical resolution as it contains the logic, ADC, and calibrated memory necessary for valid operation.
