Two control loops, run in order A single-cell charger is a current source that becomes a voltage source. Below the float voltage it holds the programmed current and the cell voltage climbs; at the float voltage the loop switches to constant voltage and holds it, and current falls as the cell fills. The cycle ends […]

Introduction A metal conductivity meter is essential for many industrial and environmental measurements. Metallic materials, primarily metals, can conduct electricity and thus be electrically charged. A metal conductivity meter is used in the industrial sector to measure the speed of current flowing through a piece of metal. A conductivity meter is a tool that
