Dimensional metrology assesses the geometric characteristics of parts and products to assure their compliance with design specifications. Dimensional calibration verifies the accuracy of product features that can affect reliability and functionality, and can be a critical step during product development or following production
Our standard reference and equipment for calibration of dimensional items used are as follows;
Long Serial Gauge Block and Gauge Block Micrometer Set, and Ceramic Caliper Checker are used to calibrate Caliper, External Micrometer and Height Gauge;
Optical Parallel / Optical Flat Set / MU Checker are used to calibrate parallelism and flatness of Caliper, External Micrometer and Height Gauge;

Calibration of Caliper (Dial Caliper / Vernier Caliper / Digital Caliper)
A Caliper is a device used to measure the distance between two opposite sides of an object. To calibrate calipers, we have two choices of master equipments, either using gauge block set or ceramic caliper checker.
For Linearity Test:
It is measured using either caliper checker or gauge block. Firstly, open the measuring jaw and then move the measuring jaws together and read the zero reading. If not zero, make necessary adjustment if possible. When using the caliper checker, keep the measuring face of the calipers parallel to the surface of the caliper checker to ensure an accurate measurement. Check reading at minimum 5 test positions which covers the measuring range of the caliper each time returning the caliper to zero reading.
For Parallelism Test:
External and internal measuring faces are calibrated using either caliper checker or gauge block between the caliper’s external or internal jaws at three different positions (start, mid and end). Repeat at least 3 times by placing a gauge block or caliper checker of different lengths.
We will test for linearity, parallelism and flatness on vernier, digital caliper and dial caliper following JIS B 7507: 1993 – Verniers Caliper
Calibration of External Micrometer
A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for precise measurement of components in mechanical engineering and machining as well as most mechanical trades.
Calibration of an external micrometer is done by using a master gauge block set and gauge block micrometer set meanwhile; for linearity and parallelism, we use optical parallel and flat set.
Calibration of mechanical and digital external micrometers includes the calibration of linearity, parallelism and flatness which follows JIS B 7502: 1994 - Micrometer Callipers.
Calibration of Height Gauge
A height gauge is a measuring device used either for determining the height of objects, or for the marking of items to be worked on. These measuring tools are used in metalworking or metrology to either set or measure vertical distances; the pointer is sharpened to allow it to act as a scriber and assist in marking out work pieces.
Calibration of linearity, parallelism and flatness of measuring jaw and scriber on vernier height gauge, dial height gauge and digital height gauge follows the JIS B 7517: 1993 - Vernier, Dial and Digital Height Gauge standard.
Calibration of height gauge uses either a gauge block set or calliper checker; and MU checker for parallelism and flatness.
Calibration of Dial Gauge / Dial Test Indicator
A Dial Gauge / Dial Test Indicator are variations of an instrument used to accurately measure small distances and angles, and amplify them to make them more obvious.
Calibration of accuracy and repeatability on Dial Gauge / Dial Test Indicator, follows JIS B 7503: 2011 – Dial Gauge and JIS B 7533: 1990 – Dial Test Indicator (Lever Type).
A coating thickness gauge is used to measure dry film thickness. Dry film thickness is probably the most critical measurement in the coatings industry because of its impact on the coating process, quality of coating and cost.
Dry film thickness measurements can be used to evaluate a coating’s expected life, the product’s appearance and performance, and ensure compliance with a host of International Standards.
It is calibrated using a thickness foil with reference to specification manual.
