[ Instrument Network Instrument Development ] On March 20, 2019, Gansu Metrology Institute successfully passed two research projects including “Study on Measurement Methods for Flame Detectors†and “Research and Development of Digital Multimeter Automatic Calibration Systemâ€. Experts accepted by the Gansu Provincial Market Supervision Administration.
The "Research on the Measurement Method of Flame Detector" has put forward the index system, simulator and other testing instruments suitable for on-site detection and corresponding detection methods by studying the principle, structure and performance of the existing flame detector. Through field application and verification, it can solve the problem that the current flame detector field detection method is not perfect.
The "Research and Development of Digital Multimeter Automatic Calibration System" is based on the JJF1587-2016 Digital Multimeter Calibration Specification. The Fluke 5522A multi-function calibration source is used as the main measurement standard. Based on the LABVIEW software platform, the project has been developed. Digital multimeter automatic calibration system. The system realizes automatic calibration of five functions of DC voltage, AC voltage, DC current, AC current and DC resistance of the digital multimeter with GPIB program control interface. The calibration function, range, calibration point and indication value are displayed in real time. , indication error, allowable error, and automatically generate calibration original records, while ensuring accurate and reliable calibration data, improve work efficiency and quality.
