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.

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.

Calibration and adjustment are different. I will explain the differences between the two. Calibration refers to assessing the health status of measuring instruments. Since it only involves checking the condition, it does not include activities to improve the accuracy errors of the instrument or to fix any malfunctions. Adjustment, on the other hand, involves bringing the measurement values of instruments closer to the values of standard instruments or ensuring they fall within the accuracy range. 【Calibration of Measuring Instruments Possible by Contec】 ■ JCSS Calibration *Note (We provide business support) ■ Calibration requiring traceability ■ Calibration requiring certification ■ Repair and calibration of various instruments ■ Measurements or calibrations requiring high accuracy ■ Regular calibration *For detailed information, please refer to the related links.

What is the calibration of an "oxygen meter" that measures oxygen concentration? To perform calibration, it is necessary to first purge all the oxygen from the piping. Our company allows a period of two weeks for this, but when the purging is completed and it's time for calibration, any defects could lead to significant time loss, so it is essential to conduct an inspection before purging. In the case of electrochemical oxygen meters, many issues occur in the cell. *For more detailed information, please refer to the related links. Feel free to contact us for more details.*

Next is the calibration of the "dew point meter" for measuring moisture content (dew point). In capacitive dew point meters, during dew point calibration, a dew point generation device is used to reproduce a desired dew point, and the sensor's sensing part, which is the device being calibrated, is actually exposed to that dew point environment for value assignment. Dew point environments are created for the number of measurement points specified by each manufacturer's calibration standards, as the values indicated by the sensor are not constant in relation to changes in the dew point. *For more detailed information, please refer to the related links.
