Abstract

The invention discloses an inductance, capacitance and resistance standard device for performing quantity transmission in the process of detecting reactance instruments by a metering department. The inductance, capacitance and resistance standard device comprises a box body, as well as wiring terminals, a selecting disc, a function identifier and connecting wires which are arranged on the box body. In work, the inductance, capacitance and resistance standard device can be flexibly connected with a variety of standard instruments for parameter combination; wiring is simple and high in accuracy; the inductance, capacitance and resistance standard device can measure and output LCR (inductance, capacitance and resistance) parameters, and can measure all parameters by once wiring; data can be directly traced back to a standard inductance (H Henry standard), a standard resistance (omega ohm standard) and a standard capacitor (F farad standard); therefore, the inductance, capacitance and resistance standard device is a standard device suitable for measurement of electromagnetic basic quantity values (inductance H, capacitance C and resistance omega) by metering institutions in all levels.

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...
