二、體視顯微鏡在使用前的調校主要有：

調焦，視度調節，瞳距調節和燈泡更換幾個步驟。下麵分別進行說明。

1、調焦：

將工作台板放入底座上的台板安裝孔內。觀察透明標本時，選用毛玻璃台板；觀guan察cha不bu透tou明ming標biao本ben時shi
，選xuan用yong黑hei白bai台tai板ban。然ran後hou鬆song開kai調tiao焦jiao滑hua座zuo上shang的de緊jin固gu螺luo釘ding，調tiao節jie鏡jing體ti的de高gao度du，使shi其qi與yu所suo選xuan用yong的de物wu鏡jing放fang大da倍bei數shu大da體ti一yi致zhi的de工gong作zuo距ju離li。調tiao好hao後hou，須xu鎖suo緊jin緊jin固gu螺luo釘ding。調tiao焦jiao時shi，建jian議yi選xuan用yong平ping麵mian物wu體ti，如ru印yin有you字zi符fu的de平ping整zheng紙zhi張zhang、直尺、三角板等。

2、視度調節：

先將左右目鏡筒上的視度圈均調至0刻ke線xian位wei置zhi。通tong常chang情qing況kuang下xia
，先xian從cong右you目mu鏡jing筒tong中zhong觀guan察cha。將jiang變bian倍bei手shou輪lun轉zhuan至zhi最zui低di倍bei位wei置zhi，轉zhuan動dong調tiao焦jiao手shou輪lun和he視shi度du調tiao節jie圈quan對dui標biao本ben進jin行xing調tiao節jie，直zhi至zhi標biao本ben的de圖tu像xiang清qing晰xi後hou，再zai把ba變bian倍bei手shou輪lun轉zhuan至zhi最zui高gao倍bei位wei置zhi繼ji續xu進jin行xing調tiao節jie直zhi到dao標biao本ben的de圖tu像xiang清qing晰xi為wei止zhi，此ci時shi，用yong左zuo目mu鏡jing筒tong觀guan察cha，如ru不bu清qing晰xi則ze沿yan軸zhou向xiang調tiao節jie左zuo目mu鏡jing筒tong上shang的de視shi度du圈quan

，直zhi到dao標biao本ben的de圖tu像xiang清qing晰xi為wei止zhi。

4、燈泡更換：

無wu論lun是shi更geng換huan上shang光guang源yuan燈deng泡pao，還hai是shi更geng換huan下xia光guang源yuan燈deng泡pao，在zai更geng換huan前qian，請qing務wu必bi將jiang電dian源yuan開kai關guan關guan上shang，電dian源yuan線xian插cha頭tou一yi定ding要yao從cong電dian源yuan插cha座zuo上shang拔ba下xia。當dang更geng換huan上shang光guang源yuan燈deng泡pao時shi
，先xian擰ning出chu上shang光guang源yuan燈deng箱xiang的de滾gun花hua螺luo釘ding
，取qu下xia燈deng箱xiang，然ran後hou從cong燈deng座zuo上shang卸xie下xia壞huai燈deng泡pao，換huan上shang好hao燈deng泡pao
，再zai把ba燈deng箱xiang和he滾gun花hua螺luo釘ding裝zhuang上shang即ji可ke。當dang更geng換huan下xia光guang源yuan燈deng泡pao時shi，需xu將jiang毛mao玻bo璃li台tai板ban或huo黑hei白bai台tai板ban，從cong底di座zuo上shang取qu出chu，然ran後hou從cong燈deng座zuo上shang取qu下xia壞huai燈deng泡pao，換huan上shang好hao燈deng泡pao；再把毛玻璃台板或黑白台板裝好即可。更換燈泡時，請用幹淨的軟布或棉紗將燈泡玻殼擦拭幹淨，以保證照明效果。
