An essential process in maintaining instrument accuracy, calibration can be both simple and complex. Accurate readings are vital to sound decision making. Accuracy of measurements can affect a company’s productivity and profitability.
The calibration process typically involves the use of specialized test equipment. Some instrument manufacturers supply testing and calibration kits with their instruments. But where accuracy needs to be ensured an expert calibration service will be employed. The equipment they utilize covers a far broader range of testing and calibration possibilities than generic manufacturer supplied equipment.
The primary reason for calibration is routine maintenance. Other reasons for calibration include the manufacturing of a new instrument or a new installation., Where an instrument has malfunctioned or been damaged, the emergency maintenance then carried out may also require calibration. Where certain changes in environmental conditions occur users may find that readings are questionable. Sudden changes in air pressure, shocks, water damage, gas leaks, corrosion are all examples of environmental changes that may call for recalibration.
Depending on the environment the instrument is being used in, different levels of calibration will be required. In accordance with legal requirements and a companies own policy the range in which an instrument is configured is decided. Legal requirements vary from one area to the next. Because of this companies will hire expert calibration technicians where they do not have their own in-house calibration specialist.
A calibration expert not only brings with them a wide array of tools and equipment but also a great wealth of experience. This allows them to problem solve and error check rapidly and efficiently. An employee unfamiliar with the process could wrestle with any problems that occur for far longer. A calibration technician can also provide reports and recommendations; identify potential areas of improvement and highlight possible performance issues. The technician must be able to investigate and troubleshoot issues affecting accuracy, especially where the cause is completely unknown.
Groups other than specialist industries can benefit from regular calibration. When services such as electricity, water or gas have improperly calibrated meters, incomes can be affected for homes, ordinary businesses and municipalities alike.
