About Platterset

Alignment Lab compares tonearm geometry trials across your chosen groove span. Inspect tracking-error curves and export every sampled point with the actual inputs.

HOW TO USE THE UPGRADE
1. Open Align → Alignment Lab. Enter the pivot distance and groove span for the record format.
2. Compare one to six trials using bundled null-point references or custom null radii. Inspect the curves and geometric values.
3. Save the comparison and export the CSV. Follow your turntable and cartridge instructions for actual adjustment.

Alignment references, overhang tools, record-format references and other turntable setup tools remain. Existing setup records are preserved under Earlier setup records.

WHAT TO KNOW
Curves sample 401 points and report sampled peak and unweighted RMS angular error. They are theoretical geometry, not audible distortion, cartridge compatibility, setup accuracy or sound-quality scores. One to six trials and up to 50 sessions. Earlier setup records remain accessible as historical heuristic worksheets.
