Frequently Asked Questions
Common questions about ISO/IEC 17025 dimensional and precision-metrology calibration at Techmaster Electronics.
What dimensional instruments does Techmaster calibrate?
We calibrate digital and vernier calipers, outside / inside / depth micrometers, dial and digital indicators, bore gauges, gauge blocks, pin / plug / ring gauges, height gauges, CMMs, optical comparators, granite surface plates, squares, sine bars, laser interferometers, profile projectors, and roundness testers.
Is dimensional calibration accredited to ISO/IEC 17025:2017?
Yes. Techmaster Electronics is ANAB-accredited to ISO/IEC 17025:2017 (Certificate AC-1736) covering dimensional measurement at our Vista, Santa Clara, and Orlando laboratories. Methods follow ASME B89, ISO 3650 (gauge blocks), and ISO 10360 (CMMs) with calibration uncertainties on every accredited certificate.
How often should gauge blocks, calipers, and CMMs be recalibrated?
Standard cycle for handheld dimensional gear (calipers, micrometers, indicators) is annual; gauge blocks every 1 – 3 years depending on grade and usage. CMMs require annual volumetric verification per ISO 10360-2. AS9100 / IATF 16949 customers typically receive uncertainty budgets sized to their tolerance limits.
Do you perform on-site CMM and surface-plate calibration?
Yes. We perform on-site CMM volumetric verification (ASME B89.4.10360.2 ball-bar or step-gauge), large-format granite-plate flatness surveys (autocollimator / electronic level), and laser-interferometer machine-tool axis checks. Our engineers travel with grade-AA artifacts and Renishaw / Keysight laser systems.
Where do you perform dimensional calibration?
In-lab dimensional calibration is performed at our Vista CA (corporate HQ), Santa Clara CA, Orlando FL, and San Antonio TX laboratories with 20 °C-controlled metrology rooms. Free local pickup and delivery is available in Silicon Valley, Southern California, and Orlando. On-site CMM and surface-plate calibration is available throughout the continental United States.
