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.

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.

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.

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.
Read the interchange reference →
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.
Read the setup guide →
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.
Read the protocol reference →
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.

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.
Read the reference →
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 →
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.

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.
