Thermocouple Calibration验证前校准、验证后检查
This is done by comparing a device or the output of an instrument to a standard having known measurement characteristics. Once the relationship is known, the device is calibrated and can be used to measure the output of other devices.
For many operations the quality of the thermocouple calibration needs to be known and is quantified by an uncertainty estimate for the calibration. This is so important for the scientific community and manufacturing operations that it has been proposed that an evaluation of the measurement uncertainty was added as part of the calibration process.
To improve the quality of the thermocouple calibration and have the results accepted by outside organizations it is desirable for the calibration and subsequent measurements to be “traceable” to the internationally defined measurement units. Establishing traceability is accomplished by a formal comparison to a standard which is directly or indirectly related to national standards (NIST in the USA), international standards.
Quality management systems call for an effective metrology system which includes formal, periodic, and documented calibration of all measuring instruments. ISO 9000 and ISO 17025 sets of standards require that these traceable actions are to a high level and set out how they can be quantified.
TQSoft™ thermal validation software can play an important role in such a quality management system. TQSoft™ has a Test Equipment Database, and can track Sensor Usage, calibration due dates and Uncertainty Management of each piece of equipment. It can also produce equipment audit reports for the use of any item of calibration equipment through to a set of validation tests performed, where the tests rely on the calibration performed with the item. This is the kind of feature vital to a good quality system.
TQSoft™ thermal validation software can interface to many leading calibration manufacturers equipment to read Reference Standard straight into the thermocouple calibration data. The process and report is 21CFR Part 11 compliant. At the same time TQSoft™ can collect and compare data from many types of data acquisition equipment to perform multi point (up to 12) sensor calibrations and calibration checks. It then stores calibration results and reports and can automatically apply the correct calibration information to test runs. It can apply straight line or polynomial fits to raw uncalibrated data, or it can download calibration set points to recorders and loggers.

热电偶校准
热电偶校准是建立测量设备和测量单位之间关系的过程。
这是通过将设备或仪器的输出与具有已知测量特性的标准进行比较来完成的。一旦知道了关系，设备就被校准并可用于测量其他设备的输出。
对于许多操作，需要了解热电偶校准的质量，并通过校准的不确定性估计来量化。这对于科学界和制造操作非常重要，因此有人建议将测量不确定度的评估作为校准过程的一部分添加。
为了提高热电偶校准的质量并使结果被外部组织接受，校准和后续测量最好“可追溯”到国际定义的测量单位。建立可追溯性是通过与国家标准（美国 NIST）、国际标准直接或间接相关的标准进行正式比较来完成的。
质量管理体系需要有效的计量系统，其中包括对所有测量仪器进行正式、定期和记录的校准。 ISO 9000 和 ISO 17025 标准集要求这些可追溯的行动达到高水平，并规定如何对其进行量化。
TQSoft™ 热验证软件可以在这样的质量管理体系中发挥重要作用。 TQSoft™ 拥有测试设备数据库，可以跟踪每台设备的传感器使用情况、校准到期日期和不确定性管理。它还可以生成设备审核报告，用于使用任何校准设备项目直至执行一组验证测试，其中测试依赖于对该项目执行的校准。这是对于良好的质量体系至关重要的功能。
TQSoft™ 热验证软件可以与许多领先的校准制造商设备连接，将参考标准直接读取到热电偶校准数据中。该流程和报告符合 21CFR 第 11 部分的规定。同时TQSoft™可以从多种类型的数据采集设备收集和比较数据，以执行多点（最多12个）传感器校准和校准检查。然后，它存储校准结果和报告，并可以自动将正确的校准信息应用于测试运行。它可以对原始未校准数据应用直线或多项式拟合，也可以将校准设置点下载到记录仪和记录仪。
