Calibration

Contec provides thorough support for the high accuracy and quality required in periodic calibration!No matter how accurately calibrated measuring instruments are, the discrepancies (instrumental errors) from standard devices due to aging cannot be avoided. Therefore, it is important to understand the current state of the measuring instruments through regular calibration.At Contec, we offer support to enhance the reliability of your products through high technology backed by a well-managed calibration environment and extensive experience.The reason measuring instruments must be calibrated repeatedly after being adjusted once is because of the phenomenon of 'aging,' which is unavoidable in all things.This is equally true for measuring instruments; components such as sensor detection parts, internal circuit boards, and the electronic components mounted on them are all affected without exception.As a result, the sensors may fail to respond correctly to measurement values, and there can be discrepancies (deviations) between the information from the sensors and the output values or displayed values.As time passes, these discrepancies (errors) gradually widen, and ultimately, they can fall outside the product's accuracy range, making regular calibration indispensable.

What is Calibration? - The Meaning of Calibration and the Reasons Why Measuring Instruments Need Regular Calibration.

What is proofreading?" "A clear explanation of the risks that arise from postponing proofreading and the disadvantages in corporate quality management.

You may be one of those who think, "I've heard the term 'calibration,' but I don't really know its meaning in detail," or "I know that measuring instruments need calibration, but I don't really understand why it should be done regularly," or "I want to have the correct knowledge about calibration, but it's a bit awkward to ask someone now." In response to those questions, Contec Co., Ltd., which has accumulated extensive knowledge and experience in calibration, repair, inspection, and testing of electronic devices, measuring instruments, and precision equipment since its establishment in 1978, will provide answers from a professional perspective. *For detailed content of the article, you can view it through the related links.

[Column] What is the 4-20mA output of measuring instruments? Is calibration necessary?

Even when the measurement value is 0, it outputs 4mA, and in the case of a disconnection, it becomes 0mA, making it easy to identify abnormalities!

The 4-20mA output is a type of analog output that outputs a current range from 4mA to 20mA, representing 0 to 100%. It is widely used as a standard analog output in measurement instruments due to the numerous advantages listed below: - It outputs 4mA even when the measurement value is 0, and it becomes 0mA in case of a disconnection, making abnormalities easy to identify. - There is no attenuation over long distances of several hundred meters (in the case of voltage output, the longer the distance, the more it attenuates due to resistance). - It is more resistant to noise compared to voltage signals. - Conversion to 1-5V is easy. For these reasons, it is adopted in many devices. *For detailed content of the column, you can view it through the related links.
