Vernier caliper calibration for manufacturing

On a Perth production floor the caliper is the first-line inspection tool for machined and fabricated parts. Gauge R&R studies and SPC data are only meaningful if the caliper itself is known to be reading correctly, which is what the calibration record establishes.

Calipers are the most-used dimensional instrument in any Perth workshop and the one most likely to have been dropped, over-tightened or used as a scribe. AmpTech calibrates vernier, dial and digital calipers in our Caversham lab against traceable gauge blocks, checking external, internal and depth measurement at points across the range.

Interval in manufacturing

12 months (6 months for final inspection)

ISO 9001; gauge control plan

Setting the interval

Twelve months is the standard workshop interval. Calipers used for final inspection or on tight-tolerance work are often placed on 6 months, with a quick gauge-block check between calibrations.

What the calibration covers

External measurement against gauge blocks at points across the range, including zero and full span
Internal (inside jaw) measurement against a gauge block stack
Depth rod measurement against a known step
Jaw parallelism and closure — light gaps at the tips show up as errors on small parts
Beam straightness and slide condition, and the zero setting on digital models

What your certificate records

The certificate format manufacturing procurement and audit teams ask for: the equipment under test, its serial number, the reference instruments used, as-found and as-left readings, environmental conditions and a traceability statement, plus the vernier caliper-specific items below.

As-found and as-left readings at each length checked, for external, internal and depth
Jaw condition and parallelism observations
Gauge blocks and reference standards used, with their traceability
Environmental conditions at the time of calibration

How manufacturing clients get vernier and digital calipers to us

Calibration is performed in our Caversham lab — not on site. We collect from and deliver back to manufacturing workshops and offices across Perth, and instruments from regional sites come by freight or via your Perth base.

Canning Vale and Bibra Lake manufacturing precincts
Welshpool and Kewdale fabrication and assembly workshops
Malaga light industrial and trade workshops
Osborne Park commercial and QC laboratories

Working with manufacturing procurement

We work with quality and production teams to align calibration intervals with your control plan, supply certificates that map directly to your gauge register, and schedule recall reminders so nothing falls out of cal during a production run.

FAQ

Vernier caliper calibration for manufacturing FAQs

How many calipers can we send at once?

As many as you like. Batches are calibrated together and returned with an itemised register that maps to your gauge list, and we can align due dates so the whole set comes due together.

What does a caliper calibration certificate actually show?

The reading of the caliper against gauge blocks of known size at several points across the range, on external, internal and depth functions, both before and after any adjustment — plus a note on jaw condition.

My digital caliper reads zero when closed — does it still need calibration?

Yes. Zero tells you nothing about the reading at 100 mm or about worn jaw tips. Calibration checks the whole range against gauge blocks.
