I'm interested in your device that measures DC and would like some additional information. Specifically, I'm looking to understand whether it can provide real-time feedback on the direction of current flow. It's crucial for my application to determine if the battery is currently charging or discharging. Could you clarify if the device has the capability to distinguish between these two states? Having this feature would significantly impact how I plan to use it in my projects. I'm eager to hear more about its functionalities and any technical specifications that might be relevant to my requirements.
