| Abstract: | The implementation of a high precision calibration instrument for MOA(Metal Oxide Ar-rester) measurement device is introduced.Its hardware components and module functions are described,and the flowchart of its software design is offered.The instrument provides a controlla-ble standard electrical source,which simulates the real working environment of MOA effectively.While supplying the standard electrical source to MOA measurement device,the measured values are compared with standard values and the calibration is then carried out.Field application shows that the instrument has advantages of low cost,high precision,better anti-interference capability and friendly man-machine interface. |
