What is Calibration?

In short, calibration is a written method in which the measurement to be measured is compared to a known value, usually a reference value.

It is worth remembering that all measurements have errors and calibration shows how many! A common example would be that when you drive your car you see that the speed is exactly 100 km / h. Then, the police stop you and realize that the speed limit is 80 km / h. The police officer gives you a ticket that shows you were driving 104 km / h. So you notice that your speedometer has an error of 4 km / h, you have just made an expensive calibration of your speedometer. The reference level used should be tracked.

Calibration traceability

Traceability is an unparalleled chain of measurements from standard measurements to international standards. In practice, this is done in several stages. Measurement values ​​are measured using a company operating scale or calibrator. The company’s performance measure should be calculated periodically using the highest reference levels, which are usually obtained from accredited calibration laboratories.

The designated calibration laboratory ensures that its references are regularly complied with in accordance with national laws. National laws are likened to international standards.

If this chain of prisoners is kept strong and kept working, it ensures that the measurements made on the factory floor are accurate and that their value is accurate.

If you buy a dose and keep using it for years without a repeat of that amount, it can be eroded from impatience or damage, and all your สอบเทียบเครื่องมือวัด calibrations are negative. This type of comparison only causes errors.

Why compare?

As mentioned above, calibration is important to ensure the quality of the finished product. There are also many other reasons for calibrations. To put it bluntly: all instruments are constantly washed away over time and lose their order from time to time. The solution ensures that the organization remains at the required level and meets the type and structure, and the requirements of governance, that the approach is adapted to protect both employees and customers, and ultimately for economic and environmental reasons.

Risks of non-correction

It is obvious to make calibrations that waste time and money. Too many calibrations waste resources, time, and money. But the cost of the calibration process should be weighed against the risks of inequality. If calibrations are neglected, they can lead to quality problems, non-compliance with production standards, production failure, risk of loss of staff and customers, economic losses, and other causes.

Disposal: If the instrument is not properly adjusted, it can lead to a loss of resources and time spent on operations, resulting in a total increase in cost.

Negative or unpredictable quality: If the device is improperly installed, there is a good chance that the type of finished product will be defective or questionable. Calibration helps to maintain the type of production at different stages, which are affected if the deviation is appropriate.

Fines or Disagree: Damaged customers can return the product and request a full refund, which is also good. But if they decide to go to court because of an injury, you may be preoccupied with the amount of money in terms of reputation and compensation.

Increased downtime: Bad end product type is the first sign that your equipment is not working properly. Regular recovery programs help give you early warning signs, allowing you to take action before another injury occurs.

Instrument calibration is as important as safety, which is a process established by the manufacturer. 

Accordingly, every company that uses equipment or instruments should make regular calibrations as defined by the manufacturers and equipment. The result of a poor measurement can often be greater than the cost of adjustment and good calibration management practices.

How often in repair?

Sometimes people ask how often measuring instruments need to be counted on a variety of types. But quality measurements do not define comparison time. You should define calibration times alone. Important points to consider when defining measurement times include the manufacturer’s measurement recommendations, uncertainty about measurement requirements, instrument stability history, past experience with similar equipment, value/value of the measure in question, and risk and consequences outside-of-tolerance conditions.

Once you start gaining experience and calibrating equipment for a long period of time, you will be able to measure calibration results and detect the risk of fidelity, so you can adjust the calibration time accordingly.
