About this app

ScaleJV is a versatile signal range converter calculator designed for automation engineers, programmers, and technicians. The app allows you to define a signal range (e.g., 4-20mA to 0-10m) and input a value to get the corresponding value in the other unit. This flexibility, along with fully customizable ranges, makes ScaleJV an essential tool for anyone working with automation systems, measurement processes, or industrial signal conversions. The app is available in multiple languages.

Key Features:

- Define custom signal ranges for automation tasks (e.g., 4-20mA to 0-10m)
- Real-time value conversion for instant feedback
- Fully customizable ranges to suit your specific needs in automation and measurement
- History of the last 20 calculations for quick reference
- Simple and intuitive interface, without ads or distractions
- Works entirely offline, no internet connection required
- Available in multiple languages
- Interactive graph to visually illustrate the calculated range and result
- Ability to create and save presets for frequently used custom ranges in signal processing

Why ScaleJV ?

As an automation programmer, I created this app to address a common need in my work: quickly converting values within defined signal ranges for automation and measurement tasks. When I couldn’t find a simple and up-to-date app for these conversions, I developed **ScaleJV** for my personal use, and then decided to make it available to others. My goal is to provide a practical, lightweight, and functional tool without the usual hassles, such as ads or subscriptions.

ScaleJV is here to help streamline your daily automation, measurement, and programming tasks!
