WHAT MEANS DIMENSIONAL CALIBRATION ?
Electrical calibration is checking condition , performance , sensitivity and accuracy of any electrical device. This is get done by applying AC or DC voltage , current , frequency or different electrical standarts.
Electrical calibration includes precise devices that evaluate the performance of key properties for other devices called units under test. Because these precise devices have thoroughly known performance characteristics compared to the test device.By this way , minimize errors is possible. Typically, the performance of such precision devices should be four or more times better than the customer's device.
Calibration is important because it helps to get accurate measurements, and accurate measurements help to optain the quality, safety and innovation of most products and services we use and rely on in our works always.
Calibration takes role on many things in the world. For example manufacturing. Without knowing accurate of production devices , it's impossible to manufacture parts or machines.
Safety and compliance with industry standards, such as those enforced by the audit and insurance organizations, are obvious reasons for keeping test and measurement tools calibrated.
WHAT TO DO
It is one of critical question in calibration world. There is no one absolute answer to fit all situations , devices and circumstances.
Calibration requirement frequency differs according to the circumstances below.
* Before a major critical measuring project
* After a major critical measuring project
* Recommendation of manufacturer calibration interval
* On special measurement
* To catch company quality policy
* After an event , like dropping , hitting , knocking
* Annual as a standard
CERTIFICATION AND ACCREDITATION
Test and measurement devices must be calibrated regularly to ensure they continue to perform their jobs properly. But where can get calibration service and from whom can it be performed ?
To ensure that you realize maximum productivity from your equipment in building the base for your own quality management program, choosing the highest possible quality laboratory is critical. You should prefer ISO/IEC 17025 Acreditted laboratories to make cooperation for your business.
Who can provide calibration in a laboratory or in field ?
