Instrument Calibration | Detailed Explanation

Instrument Calibration | Detailed Explanation 


Instrument Calibration is the process of configuring the instrument to provide a result for the samples within an acceptable range. Although the exact process can vary from product to product, the calibration process usually involves using the instrument to test samples of one or more known values ​​called "Calibrator".
Calibration is a comparison between a known measurement (standard) and a measurement using your instrument. Typically, the accuracy of a standard must be ten times the accuracy of the device being measured.For calibration of scale, a calibrated slip gauge is used

Need of Instrument Calibration

In today's industry, more devices are already being used for detectable accuracy, yet the accuracy of the instrument can be the difference between ruining the entire measurement process and getting it right the first time. If you need it or not, the question is ultimately what you and you or your quality auditing team need to decide.
The rules do not prescribe which equipment to calibrate when and when it should not. This is certainly in addition to those determined by your own quality management systems. If your company's process involves measurement using any type of instrument, then your standards may require that you can prove that the instrument provides accurate readings and can rely on it to do what it mean to measure. If this is the case, then annual calibration is common practice and will most definitely be necessary for calibration.

Importance of Instrument Calibration

The importance of calibration is not only to check that the displayed values ​​of the instrument are within the specification, but also to help you understand the inaccuracy of the displayed values ​​at specific points of measurement.
When you are calibrating an instrument, it is best to measure at the points of measurement. For example, food caterers and retailers require that they keep hot-kept food at 63 ° C or above to avoid the cultivation of harmful bacteria, so calibrating a thermometer at 63 ° C would be appropriate.
A calibration certificate proves that an instrument has been checked and verified against these critical points of measurement, and will list any errors in that instrument, which assure you to demonstrate to an auditor or client that your Instrument reading is within specified accuracy, and is fit for your desired application. The certificate will be available for most instruments that are used in a professional environment where traceable accuracy is required.
In a professional environment, calibrating an instrument based on its purchase and based on annual re-calibration as per standard procedure, but if your instrument application demands a shorter duration between calibrations, then often setting 'automatic re-Set' is the best. It is good practice, also a Call process with qualified laboratory technician also help, In this way you will always be reminded that when your instrument is about to be calibrated, and without your prior knowledge the accuracy of the instrument will not be compromised.
If you are using an instrument that is not calibrated, then it is assumed that your measurements may be considered unreliable and incomplete to national or international standards in a professional environment.

Why Calibration is Required?

Virtually all appliances degrade over time in a rough fashion. As components age, they lose stability and drift from their published specifications. Normal handling can also adversely affect calibration, and rough handling can throw equipment out of calibration altogether, even if it appears to be physically fine. Regular calibration assures that the equipment consistently meets the required specification. Having a well-designed and organized calibration program often results in quality, productive efficiency and increased revenue.

When we need Instruments Calibration?

Calibration intervals can vary within an industry or plant. The frequency depends on the equipment and application. As a rule, however, calibration must be done at least once a year. In more critical applications, the frequency will be much higher.

Who performs the Instrument calibration?

When planning and implementing a calibration program, it is important to use a provider who is qualified and follows a national standard. Choosing a company to the ISO 17025 standard is the best option, and in some industries, required. ISO / IEC 17025: 2005 specifically refers to the requirements of testing and calibration laboratories and lays down very stringent standards for those using it, Accredited calibration providers, such as Precision Calibration Systems, monitor through their accrediting bodies with very specific quality management system requirements, with regular audits and reviews. What makes Precision Calibration Systems stand out from the competition is our customer accountability and turnaround time
