| Abstract: | The instrument which can measure the impulse grounding resistance directly is designed.The measuring instrument uses the advaced DSP TMS320LF2407A and complex programmable logic device MAX7128AE that are made by TI company as the main chip collects the voltage and current signels at the same time,while the device extends 1M words FLASHROM outside.The theoretical basis of measurement methods is introduced and the accuracy of the device is verified by actual measurement. |
