光軸之檢驗
To check if the optical axis of EDM and theodolite are matched, follow the procedure
below. It is especially important to check after adjustment of the eyepiece reticle is carried
out.
c
Position the Instrument and prism with about 2m apart and face them at each other.
(At this time, the power is ON. )
d
Sight through the eyepiece and focus to the prism. Then center the prism on the cross
hairs .
e
Set to the measure mode to distance measurement or set audio.
f
Sight through the eyepiece and focus the (blinking) red light spot by turning the
focusing knob in the direction of infinity (clockwise). If displacement of the reticle cross
hairs is within one-fifth of the diameter of the round red light spot both vertically and
horizontally, adjustment will not be required.
Note: If displacement is more than one-fifth in the above case, and still remains so after
rechecking the original line of sight, the instrument must be adjusted by competent
technicians. Please contact TOPCON or your TOPCON dealer to adjust the instrument.
