| Abstract: | The error resources of detectors made up of nominal instrments at themain of ZX78 resistance and ZY4 dourble bridge checker are found, the quantitativeanalysis is made. Then all indefinite degrees of portable double and single bridge ofthe detector are catcuIated. Finally the detector is verlfied to meet JJG 125-86 DCelectric bridge detecting regulation. |
