1. A method performed by a computer processor, comprising:
- detecting the presence of a communicatively coupled path between the processor and a process control device;
measuring an electrical characteristic of the communicatively coupled path;
retrieving an electrical requirement of a communication protocol of the process control device from a memory device;
calculating a deficiency in the presence of the communicatively coupled path, and between the electrical characteristic and the electrical requirement;
retrieving an electrical mitigation that reduces the deficiency from the memory device; and
rendering the electrical mitigation on a display device.

Abstract
Multi-functional field maintenance (FM) tools that connect to process control devices, such as FOUNDATION Fieldbus and Highway Addressable Remote Transducer devices, can automatically detect and simultaneously identify communications, troubleshoot connections, and supply power in a process control plant. Simplifying the troubleshooting process, by guiding a user of a multi-functional FM tool through recommended troubleshooting steps, while simultaneously detecting and correcting issues reduces the number of tools required to maintain process control devices, reduces the risk of damage, and improves efficiency by minimizing production downtime.
