The following will introduce the instrument calibration method of thermocouple temperature transmitter: pay attention to the risk control of explosion, pay attention to the degree of protection and certification mark, and suffocate the wrong polarity of the power supply, which may lead to unknown results. Instrument detection method of thermocouple thermostat: because it is 5V, input the resistance value range of the corresponding sensor and three transmitters listed on the nameplate, 1V output. According to the input resistance value of the bisected point range, within the accuracy range, check the temperature of the line output. Technical indicators, according to the knowledge of the test, determine the technical requirements that need to be met The instrument calibration method of the thermocouple temperature transmitter: and the range on the nameplate of the transmitter, 1V and 5V output, listed separately, when you enter the corresponding Resistance value sensor. Based on the equivalence point potential value of the input range, please specify the accuracy range along the output temperature. All equipment used for testing and/or calibration, including auxiliary measuring equipment that significantly affects the accuracy or validity of testing, calibration and sampling results (such as those used to measure environmental conditions), should be calibration. The laboratory shall develop plans and procedures for equipment calibration. A calibration laboratory is linked by an unbroken chain of calibration or comparison to the SI unit reference of the corresponding measurement to establish the measurement standard and the traceability of the measuring instrument to SI. Links to SI can be achieved by referring to national measurement standards. National measurement standards can be datums, which are primary implementations of SI units or expressions agreed upon in SI units based on fundamental physical constants, or secondary standards calibrated by other national metrology institutes. When using an external calibration service, the calibration service of a laboratory that can demonstrate qualification, measurement capability and traceability should be used to ensure traceability of measurements. Calibration certificates issued by these laboratories should include measurement uncertainty and/or a statement of compliance with established metrological specifications. Jiutian Instrument provides you with an international authoritative measurement and calibration service technical certificate scheme Instrument calibration and other services. Accurate, efficient and timely.
