Abstract

The invention discloses a standard device for inductance, capacitance and resistance used for value transmission in the process of detecting reactance instruments in the metrology department. Connecting lines and other components. When this standard device is working, it can be flexibly connected to various standard instruments for parameter combination. The wiring is simple and the accuracy is high. It can not only measure LCR parameters, but also output LCR parameters. All parameters can be measured with one connection, and the data can be directly traced to the standard. Inductance (H Henry standard), standard resistance (Ω ohm standard), standard capacitance (F farad standard), is a standard suitable for measurement institutions at all levels to establish electromagnetic basic values ​​(inductance H, capacitance C, resistance Ω) measurement device.

Description

technical field [0001] The invention relates to a measuring device, in particular to a standard device for inductance, capacitance and resistance used for transferring values ​​from a high level to a low level during the process of measuring, detecting and calibrating resistance, capacitance and inductance instruments. Background technique [0002] At present, when the metrology department detects AC parameter instruments such as capacitance boxes, inductance boxes, reactance boxes, and LCR measuring instruments, it needs to use a variety of standard instruments such as standard resistance, standard capacitance, and standard inductance to perform parameter combinations to complete the measurement. However, the wiring of this measurement method is complicated, the measurement accuracy is low, and the measurement of all parameters cannot be completed with one connection. It is necessary for this industry to develop a standard device for inductance, capacitance and resistance t...
