Reference + hands-on practice

This guide has two halves: the reference procedures below (pick an indicator at left), and hands-on practice trainers for every unit — jump to Practice Mode ↓.

Choose an indicator from the list to see its calibration procedure.

▣ Practice Mode

Tap the keys — no scale required

Every indicator in the reference above has a hands-on trainer here, drawn to match the real panel down to the hidden keys. The next key glows, the display responds like the real unit, and a wrong key gets flagged. The Libra Cart is app-based, so its trainer is a phone walk-through. Nothing here touches a live scale.
