Second reflecting mirror is attached on zero point arm part；
By the first autocollimator emergent light by half-reflecting half mirror, the second mirror imager the first autocollimator graticle
The first cross-graduation picture is formed, the first autocollimator emergent light is imaged on the first auto-collimation through the second reflecting mirror, half-reflecting half mirror
The second cross-graduation picture is formed at the graticle of instrument.
When the first cross-graduation picture is overlapped with the second cross-graduation picture, the angle of half-reflecting half mirror and the second reflecting mirror is 90 °；
When the first cross-graduation picture and the second cross-graduation picture are located at division line two sides, the appearance of the second reflecting mirror is adjusted
State is overlapped the first cross-graduation picture with the second cross-graduation picture.
8. bio-measurement instrument zero point arm adjustment method according to claim 2, which is characterized in that described by fixing
The position of half-reflecting half mirror, the first autocollimator and the second reflector alignment third reflecting mirror, specifically includes:
Third reflecting mirror is attached on zero point arm part；
Incident ray reaches third reflecting mirror through half-reflecting half mirror, the second reflecting mirror, observes reflection light in the first autocollimator
Whether the cross-graduation picture at place is overlapped with the cross division line of the first autocollimator；
If not being overlapped, the posture of third reflecting mirror is adjusted, so that cross-graduation picture and the first auto-collimation at the first autocollimator
The cross division line of instrument is overlapped.
