FEATURES
.Distance and angle measuring functions are synthesized in the i
)SDM3E. Accurate and rapid operation can be executed with I
the SDM3E. i
.Horizontal dist~nce.height difference and coordinate are com- l
¡:
puted and displayed by keying in angle.
.Successive and tracking measurement as well as stake-out can
I
be selected. ¡
.The telescope can be plunged to either direction, enabling the
¡ ,
user to observe both faces, easily. l
.Adjustment of light intensity is not necessa¡y. 'L
.Incoming reflection from prism(s) is confirmed by light value
lamp or buzzing sound.
.All the necessary information is displayed.
.Function to output the measured data is provided.
.Corrections for earth-curvature and refraction are carried out
automatically.
.The SDM3E's power source is cut off two minutes after its last
operation. This saves battery capacity.
.. A convenient handle is provided for easy transportation.

V OPERATION
1. Setting up the SDM3E
(I) Setting up the tripod
I) Loosen wing nuts A.
A
Fig. 4
2) Keep tripod closed and raise the tripod head to about chin
leveL. Tighten wing nuts A.
3) Spread the tripod legs so that the three shoes form an
equilateral triangle and the tripod head is positioned
directly over the surveying point.
4) Make sure that: i. the tripod head is approximately
level, 2. the tripod shoes are firmly fixed in the ground.
Fig. 5
If the ground is not solid enough, drive wooden stakes on
which shoes are set.
