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.
