We go back to the measurement principle of a digital level, and examine the reading accuracy. Hereafter, as long as there is no notice in particular, we treat the digital level NA 3000 and staff GPCL3 manufactured by Leica. When using a digital level, we most worry about whether a level recognizes a sta scale correctly or not. Moreover, we also want to know the measurement accuracy. In this case, the quantity which must be grasped at least is the minimum resolution of a reading, and proportional relation between a reading and a staff scale. The results of our examination mostly confirm the characteristic of specifications given by Leica. The resolution of measured value was decided as 20 micrometers or less at the maximum. Furthermore, the error of linearity was presumed to be about 20 micrometers over 3m staff. Since the stability and setting accuracy of horizontal axis are the basic performance of a level, we made those examinations of Leica digital level in the second half part of the report.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜総説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71721","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKEDA, Toyotaro"}]},{"nameIdentifiers":[{"nameIdentifier":"71722","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOYAMA, Etsuro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032188","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11602838","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute，University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学地震研究所技術部総合観測室"},{"subitem_text_value":"Technical Supporting Section for Observational Research, Earthquake Research Institute, the University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"竹田, 豊太郎"}],"nameIdentifiers":[{"nameIdentifier":"71719","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小山, 悦郎"}],"nameIdentifiers":[{"nameIdentifier":"71720","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"11_001-010.pdf","filesize":[{"value":"1.4MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"11_001-010.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32197/files/11_001-010.pdf"},"version_id":"8736b0bf-f7a0-412f-ac97-da53276af4ba"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Digital level","subitem_subject_scheme":"Other"},{"subitem_subject":"Minimum resolution","subitem_subject_scheme":"Other"},{"subitem_subject":"Accuracy for digital reading","subitem_subject_scheme":"Other"},{"subitem_subject":"Stability of aiming axis","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"デジタルレベルの測定精度について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"デジタルレベルの測定精度について","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4477","4478"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32197","relation_version_is_last":true,"title":["デジタルレベルの測定精度について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:30:21.177125+00:00"}
