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.

Refer to Fig. I. page I.
o Handle
f) Battery case cover
ê Connector
Used for data output.
Ð Instrument height mark
o Illumination slot
o Reflector
Ð Peep sight
e 00 index
When the circle positioning ring æ is turned until the 00
button on the ring comes directly below the 00 index, 00
graduation is seen through the micrometer eyepiece.
o 00 button
This shows the location of 00 graduation of the horizontal
circle.
æ Lower fine motion
CD leveling screw
æ Tribrach
æ Clamp screw of swivel lever
Loosen the clamp screw immediately after you receive the
instrument.
æ Swivel lever
When this is given half a turn in an anticlockwise direction, it
is possible to lift the main body from the tribrach.
æ Base plate
d\ lower clamp
4D Circular level adjusting screw
The circular level adjusting screws can be turned with the
adjusting pin to center the circular level bubble.
Gi Circular level
., Circle positioning ring
When the lower clamp CD and horizontal clamp 0 are
loosened, the horizontal circle can be turned with the ring.
tI Eyepiece for optical plummet
Turn the eyepiece to focus on the reticle.
