About

Linear Interpolation Master

This tool simplifies linear interpolation calculations for industrial commissioning engineers. It features large, easily readable numbers for field use and allows for quick swapping of coordinate systems, such as converting between 4-20mA and 0-100% scales.

Highlights
  • Large number display for field visibility
  • Quickly swap X and Y coordinates
  • 4-20mA to 0-100% conversion
  • 0-100% to 4-20mA conversion
