NSSL EFM Redesign

This repository contains all files and relevant information for the electric field meter (EFM) designed for NSSL. This instrument has been in existance for many years, but beginning in approximatley 2019/2020 Leeman Geophysical was contracted to help design and implement the next generation of the device. This README should be a living document keeping the most current and relevant information on the assembly, operation, and programming of the instrument.
