# Troubleshooting

### Measurement Errors

The cabling for the current transformer should be held as short as possible. In case of significant measurement errors after Installation, please consider the following points:

* The use of Rogowski ­coils as current transformers for the converter counter is discouraged because of the multiple current / voltage transformation and external amplifiers. Each transformation adds a multiplicative error on the measurement.
* Energy Direction (current transformer) : If all currents are expected to be positive (import measurement) but one or several currents are negative, please check the correct installation of your current­ transformers as they have been wrongfully installed.
* Transformer Ratio (current transformer) : The transformer ratios on the meter must be the same as the ones of the installed current / voltage transformers.
* Correct Phase assignment: Current L1 and Voltage L1 must be connected to the same measurement system. See Connection Diagram.

### **Reporting Bugs and Issues**

If you encounter a bug or an issue that is not covered in the documentation or you suspect a technical problem, please report it to our support team. To facilitate the resolution process, include the following information:

* A detailed description of the issue.
* Steps to reproduce the problem, if possible.
* Any error messages or warnings.
* Information about your device, lorawan network, and any other useful information.

### **Continuous Improvement**

We are committed to improving the performance and user experience of our devices. Your feedback is valuable in helping us identify and address issues, so don't hesitate to reach out with any problems or suggestions.
