What: A calibration and testing are procedures in which an instrument, tool, or device is tested to confirm that it conforms to the standard. Calibration is very important, as it ensures that objects are working properly. There are a number of reasons to conduct a calibration test, ranging from concerns that something is not working as it should be in preparations for an event in which very precise calibration is desired, and there are a number of ways to perform a calibration.

In some cases, people may conduct their own calibration tests. For example, a supermarket might check the accuracy of its scales every week with an object of a known weight. Market employees would zero out the scales, place the object on the scale, and take a reading before zeroing the scale out again and weighing a second time. For thoroughness, several different weights would be tried, to confirm that the scale can handle a range of weights. If inaccuracies were identified, the scales would need to be repaired, adjusted, or replaced. Calibration test kits are available for many common instruments and tools so that people can perform equipment calibration on their own.

The initial salary can be between 15-20,000 per month, which vary in private, and government firms.

How: Typically calibration and testing professionals chart the sequence of testing and calibration for instruments and equipment as per the blueprints, schematics, technical manuals and other specifications. They meticulously conduct preventive and corrective maintenance of peripheral equipment and test apparatus. To excel in this field you need good communication skills backed by logical thinking to interact with engineers, supervisors and other technical workers to assist with equipment installation, maintenance and repair techniques. Hone your maths, stats and algebra skills, as you will be required to analyse and convert test data, using mathematical formulas and report results and proposed modifications.

Determining causes of operating errors and deciding what to do about it is another major area of work that you will need to undertake. Work opportunities exist in calibration labs and industries engaged in electro-technical, mechanical, radiological, thermal and optical and fluid-flow measurements. You can also work with various MNCs, PSUs, R&D centres and SMEs that require calibration and testing services.

Where: New Delhi (www.stqc.nic.in) offers a post- diploma in test engineering, calibration & maintenance of electronic equipment. Regional Testing Centre, Chennai, offers entrepreneurial and skill development programmes in calibration of measuring instruments (mechanical/electrical and electronics).

The eligibility for this course is: Degree/diploma in engineering in relevant field. After gaining some work experience and expertise in the field, you can opt for some of the advanced training courses offered by National Accreditation Board for Testing & Calibration Laboratories (NABL), New Delhi (www.nabl-india.org).
