I — Documentation

SVEND Technical Documentation

Stable references for how SVEND studies, data interfaces, and integrations work. A documentation page distinguishes what is available today from what is proposed, under validation, or deliberately outside the product boundary.

Ref: Product contracts · Integration boundaries · Validation status

II — Studies

Measurement study · Available

Gage R&R study bench

Declare parts and appraisers, issue a randomized run sheet with a recorded seed, capture readings off the instrument, and judge the completed study by ANOVA against a record whose readings are hash-chained.

Read the study reference →
Experiment study · Pro

DOE study bench

Declare factors in their real units, generate one of seven design families, carry a randomized run sheet to the line, and fit the effects against the design that produced them.

III — Interfaces and integrations

Interactive SPC instrument · Free

Control chart selector

Choose among I-MR, X-bar/R, X-bar/S, p, np, c, and u charts, then run documented manufacturing datasets through the Meganeura engine.

Data interface · Available

Import and export

Upload CSV data, paste comma- or tab-separated tables, and export analysis results as CSV, Excel, or structured JSON.

Read the data reference →
Data interface · Available

Minitab worksheets

Open an .MTW worksheet on the bench, run the study, and take a worksheet back out, including a Gage R&R in the column shape the analysis expects on the other side.

Device interface · Available

Digital gages and keyboard wedges

Capture numeric readings from USB and Bluetooth devices that behave as a keyboard, with Enter advancing the randomized Gage R&R run sheet.

Protocol reference

The Digimatic frame

What the SPC output on a Mitutoyo gage actually sends (thirteen nibbles carrying a value, a sign, a decimal position and a unit) and what its omissions mean for traceability and Gage R&R.

Interface compatible · Validation pending

Sylvac Bluetooth HID

Use the standard keyboard interface already accepted by SVEND with Sylvac instruments configured for Bluetooth HID operation.

Read the compatibility guide →
Keyboard available · Identified serial proposed

MicroRidge MobileCollect EVO

Connect Mitutoyo U-WAVE-T, U-WAVE-TM, and U-WAVE-TC transmitters to SVEND through a MobileCollect EVO base. Covers the keyboard-wedge path available today and the proposed identified USB-serial collector.

IV — Calibration

Reference material on the calibration program around a measurement system. SVEND does not sell calibration management; these pages exist because the questions they answer decide whether a measurement record is worth anything, and nobody writes about them.
Reference

When a gage fails calibration

The exposure window, the seven steps of an impact analysis, and the eleven things a records system must already hold for reverse traceability to be possible at all.

Read the recall reference →
Reference

Calibration intervals

An interval is a bet on end-of-period reliability. Where the number on a register came from, what setting one properly requires, and why the data it needs is usually thrown away.

Read the interval reference →
Reference

The gage register and the crib

Why a register identifies instances and not models, marking that survives a shop floor, what a check-out record is metrologically worth, and the two crib failure modes almost nobody fixes.

Read the register reference →
Reference

Tracking gages in a spreadsheet

The real incumbent, assessed honestly: the two different jobs a spreadsheet is doing, where each one breaks, and why a value in the wrong row is worse than a typo no matter how it got there.

Read the assessment →
Reference

Electronic signatures on certificates

What an advanced electronic signature proves and what it cannot, the four PAdES levels, why a self-reported signing time is not evidence of when, and why the standard names a person rather than a system.

Reference

The Digital Calibration Certificate

One format instead of an integration per laboratory. What a DCC carries, why a unit written as text is not a unit, and the three questions a document format does not settle.

Read the format reference →

V — Instruments

One page per instrument class, identically structured, each ending with the section no reference library on the web carries: how a reading actually gets off the tool.
Reference · Shared physics

The instrument reference

Abbe error, cosine error, temperature and measuring force: four mechanisms that recur through every instrument class, and why resolution is not accuracy.

Read the shared physics →
Reference · Instrument

Calipers

A 0.01 mm display on a ±0.02 mm instrument, a structurally Abbe-violating geometry, and the one holding instruction worth more than all the others combined.

Read the caliper reference →
Reference · Instrument

Micrometers

Why it beats a caliper by an order of magnitude for three structural reasons, and why a large frame must be zeroed in the orientation it will be used in.

Read the micrometer reference →

VI — Reading status

Available means the behavior is present in the running product. Proposed means the design is public for review but is not a claim that the complete integration ships today. Under validation means hardware or reference testing is in progress.

Manufacturer names identify compatibility targets. They do not imply that the manufacturer has reviewed, certified, sponsored, or endorsed SVEND unless a page explicitly says so.
