1. Kuenderana kwerutivi rwemupendero wakatwasuka pakatarisana nenzvimbo yekushanda: Isa mupendero wakatwasuka wegranite paplate yakatsetseka. Pfuura mupendero we dial gauge, wakashongedzwa nechikero che 0.001mm, nepabhawa rakatenderera rakajairika wobva waisa zero pa sikweya yakajairwa. Wobva waisa mupendero we dial gauge padivi rimwe remupendero wakatwasuka. Kuverenga mupendero we dial gauge ndiko kukanganisa kwe perpendicularity kwedivi iroro. Saizvozvowo, edza mupendero we perpendicularity kune rimwe divi, wobva watora mupendero we maximum error.
2. Chiyero cheNzvimbo yeKubata yeParallel Straightedge: Isa chinhu chinoratidza panzvimbo yekushanda yestraightedge ichaedzwa. Gaya pamusoro payo paplate yesimbi yakakandwa kana straightedge ine kururama kwakafanana kuti uratidze nzvimbo dzakasiyana dzekubatana panzvimbo yekushanda. Wobva waisa pepa rinoonekera (senge pepa replexiglass) rine masikweya madiki mazana maviri e2.5mm x 2.5mm, rinoyera 50mm x 25mm, chero panzvimbo yekushanda yestraightedge ichaedzwa. Tarisa chiyero chenzvimbo yesquare yega yega ine nzvimbo dzekubatana (mumayuniti e1/10). Verenga huwandu hwezviyero zviri pamusoro apa wopatsanura ne2 kuti uwane chiyero chenzvimbo yekubatana panzvimbo yenzvimbo yakaedzwa.
Chechitatu, tsigira ruler yakafanana nemabhuroko akaenzana pamatanho ekutsigira akajairika 2L/9 kubva kumagumo ese eruler. Sarudza bhiriji rekuyera rakakodzera zvichienderana nehurefu hwenzvimbo yekushandira yeruler (kazhinji nhanho 8 kusvika ku10, ine span iri pakati pe50 ne500mm). Wobva waisa bhiriji kune rimwe divi reruler woisa reflector kana level pariri. Fambisa zambuko zvishoma nezvishoma kubva kumugumo mumwe weruler kuenda kune mumwe, uchifambisa span yega yega kubva pa autocollimator ine graduation ye1″ (kana 0.005mm/m) kana electronic level ine graduation ye0.001mm/m (kune kureba kwenzvimbo yekushanda inodarika 500mm, ruler yeClass 1 ine graduation ye0. Kuverenga panzvimbo iyi kunogona kutorwa ne 0.01mm/m coincident level (level yefuremu ine graduation ye0.02mm/m inogona kushandiswa padanho rechipiri). Musiyano uripo pakati pekuverengwa kwepamusoro nepadiki ndiko kukanganisa kwekutwasuka kwenzvimbo yekushanda yenzvimbo. Kune chero 200mm yenzvimbo yekushanda, kukanganisa kwekutwasuka kunogona kuonekwa uchishandisa 50mm kana 100mm bridge plate, uchishandisa nzira iri pamusoro.
IV. Kufanana kwenzvimbo dzepamusoro nedzepasi dzekushanda, uye nzvimbo yekushanda nedzepasi dzekutsigira, dzedanho rakafanana. Kana pasina plate yakatsetseka yakakodzera, divi redanho rinogona kuiswa panzvimbo yekutsigira uye musiyano wekukwirira kwedanho wakayerwa uchishandisa lever micrometer ine graduation ye0.002mm kana micrometer ine graduation ye0.002mm.
