I-YYT703 Mask Vision Field Tester
I-low-voltage bulb ifakwa endaweni yenhlamvu yeso yokuma kwekhanda elijwayelekile, ukuze indawo yokukhanya ye-stereoscopic ekhishwa isibani ilingane ne-engeli ye-stereoscopic yesilinganiso sensimu yokubona yabantu abadala baseShayina. Ngemva kokugqoka imaskhi, ngaphezu kwalokho, i-cone yokukhanya yancishiswa ngenxa yomkhawulo wefasitela leso lemaski, futhi iphesenti lekhoni yokukhanya elondoloziwe lalilingana nezinga lokulondolozwa kwensimu ebonakalayo yohlobo olujwayelekile lwekhanda eligqoke imaski. Imephu yenkundla ebonakalayo ngemuva kokugqoka imaskhi ikalwe nge-perimetry yezokwelapha. Ingqikithi yendawo yokubuka yamehlo amabili kanye nendawo yenkundla yebhinobhore yezingxenye ezivamile zamehlo amabili kwalinganiswa. Amaphesenti ahambisanayo enkambu ephelele yombono kanye nenkambu ye-binocular yombono angatholakala ngokuwalungisa nge-coefficient yokulungisa. Inkambu ephansi yombono (idigri) inqunywa ngokwendawo yephuzu eliphansi lokuwela lebalazwe lensimu yebhinoni. Ukuthobela: GB / t2890.gb/t2626, njll.
Leli bhukwana liqukethe izinqubo zokusebenza kanye nezinyathelo zokuphepha. Sicela ufunde ngokucophelela ngaphambi kokufaka nokusebenzisa ithuluzi lakho ukuze uqinisekise ukusetshenziswa okuphephile nemiphumela yokuhlolwa enembile.
2.1 ukuphepha
Ngaphambi kokusebenzisa i-sgj391, sicela unikezwe isitifiketi sokufunda nokuqonda konke ukusetshenziswa nokuphepha kukagesi.
2.2 Ukuphelelwa amandla kwezimo eziphuthumayo
Esimeni esiphuthumayo, khipha ugesi wepulaki ye-sgj391 futhi unqamule zonke izinsiza zikagesi ze-sgj391. Ithuluzi lizomisa ukuhlola.
I-Radius ye-arc arch semicircular (300-340) mm: ingazungeza iqonde evundlile idlule ku-0 ° yayo.
Umumo wekhanda ojwayelekile: umugqa ongaphezulu wesibani sedivayisi yokuma komfundi ngu-7 ± 0.5mm ngemuva kwephoyinti eliphakathi lamehlo amabili. Ifomu lekhanda elijwayelekile lifakwe ebhentshini lokusebenza ukuze amehlo angakwesokunxele nakwesokudla abekwe ngokulandelana phakathi nendawo ye-arc arch semicircular futhi abheke ngqo iphuzu layo elithi "0".
Ukunikezwa kwamandla: 220 V, 50 Hz, 200 W.
Ukuma komshini (L × w × h): cishe 900 × 650 × 600.
Isisindo: 45kg.
