OPERATION
Initial Operation
!WARNING Protect the instrument
against moisture and
direct sun light.
Do not subject the instrument to extreme
temperatures or variations in temperature.
As an example, do not leave it in vehicles
for long time. In case of large variations
in temperature, allow the instrument
to adjust to the ambient temperature
before putting it into operation. In case
of extreme temperatures or variations
in temperature, the accuracy of the
instrument can be impaired.
Avoid heavy impact or falling of the
instrument. After heavy exterior impact on
the instrument, an accuracy check should
always be carried out before continuing
to work.
Setting Up Instrument
!WARNING It is important that the
tripod is set up firmly.
Make sure that the tripod points are well
into the ground. On paved surfaces, be
sure the points hold securely.
The legs should have about a 3-1⁄2 foot
spread, positioned so the top of the tripod
head appears level.
If using a tripod with adjustable legs, be
sure the leg clamps are securely hand
tightened.
Before setting up your instrument, be sure
clamps are loosened and both telescope
lock levers are in the closed position.
Attach the instrument to the tripod
securely, hand tightening the instrument
base to the 5/8-11 tripod head.
Setting Up Over a Point
!WARNING Never use force on any
parts of the instrument.
All moving parts will turn freely and easily
by hand.
The DT8-05P and DT8-05LS is equipped
with an optical plummet. The DT8-05LP
is equipped with a laser plummet.
This eliminates the need to use a plumb
bob. The instrument is set up over a
reference point by looking through an
eyepiece and optically lining up over the
point (DT8-05P and DT8-05LS) or using
the laser plummet beam (DT8-05LP).
Move the tripod and instrument over the
approximate point. (Be sure the tripod
is set up firmly again. Loosen leveling
screws and shift the instrument laterally
until the instrument is positioned directly
over the point.
Positioning Directly Over Point Using
Optical Plummet
When looking through the eyepiece 11
the light path is reflected through center
of the instrument to the reference point (a
stake on the ground).
- Line up the tripod over the reference
point.
- Remove the plumb bob hanger from
the center stud of the tripod.
- Attach the instrument to the tripod.
- Level the instrument.
- Use the optical plummet to view the
reference point on the ground. Sight
through the optical plummet eyepiece
11 located beneath the telescope
eyepiece.
- Turn the optical plummet eyepiece 11
to bring the crosshairs into focus.
NOTE: The image seen in the eyepiece is
reversed left to right. This is important to
remember when shifting the instrument or
tripod to center over the reference point.
- Line up the crosshairs with the
reference point.

-10-
If necessary, the instrument can be shifted
by loosening the tripod center stud and
sliding the instrument from side to side for
proper positioning.

button. A laser point
will project through the center of the
instrument to the reference point (a stake
on the ground).
- Line up the tripod over the reference
point.
- Remove the plumb bob hanger from
the center stud of the tripod.
- Attach the instrument to the tripod.
- Level the instrument.
- Line up the laser point with the
reference point.
If necessary, the instrument can be
shifted by loosening the tripod center stud
and sliding the instrument from side to
side for proper positioning.
Leveling the Instrument
Center the instruments circular vial 8by
carefully extending or shortening the
tripod leg closest to the bubble. Caution:
Use only two legs. Repeat until alignment
is within 1/4-in (6 mm).
Set the instrument leveling screws. Turn
down the leveling screws 12 until firm
contact is made with the instrument base.
!CAUTION Do not overtighten the
leveling screws. It is
very possible to overtighten the leveling
screws. Only a firm contact between the
screws and the base is necessary. If the
instrument shifts on the base, turn down
the screw more firmly by hand.
Leveling the instrument so the vial bubble
remains centered through a 360° rotation
of the telescope is the most important
operation in preparing to use your
instrument.
When leveling your instrument, be sure
not to touch the tripod. Follow these
instructions carefully.
Use the tubular vial 17 to accurately level
the instrument. Unlock 13 and turn the
instrument so that the tubular vial 17 is
parallel to BC, any two leveling screws.
- Note the direction to turn the leveling
screws. When turning the two screws,
adjust them equally. The bubble will
move in the direction that your left
thumb turns.
- To move the bubble to the right, turn the
B leveling screw in and simultaneously
turn the C leveling screw in.
- To move the bubble left, move both
screws out simultaneously.
Once centered turn the instrument 90˚
over Aleveling screw and turn screw Ain
or out until bubble is centered.
Go back to the first position BC, and
repeat until the bubble is centered in both
positions. Then from position BC turn 180˚
to check the adjustment.
If the bubble stays centered or within ¼
division, you are leveled.
Next, check the ground point centering. If
you are not directly on the point, carefully
loosen the tripod fastener and move the
instrument on the tripod head in an x - y

-11-
direction. Do not rotate the instrument.
Recheck leveling and repeat until
instruments is level and over the ground
point at the same time. With practice, this
becomes easier.
Telescope Eyepiece Focus
Adjustment of Eyepiece
Direct the telescope to a bright
background. Turn the eyepiece ring so
that the crosshairs of the reticule are
clearly seen.
Elimination of Optical Parallax
Adjust the focusing ring to clearly see an
object on the reticule. Move your eyes up
and down to see if the image of the object
moves relative to the graduation lines.
If it does not move, there is no optical
parallax; otherwise turn the focusing ring
to eliminate the optical parallax.

• Move the telescope up and down
when the instrument is at the normal
position. The beeper beeps and the
LCD displays the vertical angle. The
instrument enters into measuring
mode.
• After the power is switched on and
the instrument has entered into
measuring mode, the battery level is
indicated by the battery symbol in
the lower right corner of LCD.
• If all of the three squares are
displayed, the battery is fully charged.
• Decreasing squares indicates
reduction of charge.
• If the battery symbol blinks, the
battery is low and needs recharging
or replacing.
Measurement of Angle
Observing in the “Normal” and “Reverse”
Positions of the Telescope
The normal, or direct, position of the
telescope refers to observation with
the vertical circle being on the left. The
reverse position refers to observation
with the vertical circle being on the right.
The mechanical errors can be offset by
averaging the values measured in the
normal and reverse positions.
Normal Reverse
Measurement of Vertical Angle
• 0° angle position can be set as
follows in the initial setting:
ZEN==0
(Zenith 0°)
ZEN==90
(Zenith 90°)
90° 270°
180°
0°
0° 180°
270°
90°

-13-
Compensation of the Tilt Sensor to
Vertical Angle
• If the instrument is inclined
within ±3’, the tilt sensor can
compensate the vertical angle.

CHECKS AND ADJUSTMENTS
Removal
• Turn the screw on the tribrach locking
Lever 13 outward using a flat screw driver
to its stop.
• Turn the tribrach locking lever 13 180°
counterclockwise. Holding the base with
one hand, take the main body off the base.
Attachment
• Turn the tribrach locking lever 13
counterclockwise until it reaches the
position limit.
Align the positioning block on the main
body of the instrument to the notch on the
base. Install the main body onto the base.
• Turn the tribrach locking lever 13 clockwise
until it reaches the position limit so that the
‘v’ mark points downward.
• Turn the screw inward until it hits its stop.

When attempting to check and adjust the
instrument, corrections must be made in
a certain order to ensure the adjustments
are correct.
Order of adjustment:
1. Check and adjust the tubular plate
vial 17.
2. Check and adjust the circular leveling
vial 8.
3. Check and adjust the optical
plummet 11 (DT8-05P & DT8-05LS)
Always recheck your adjustments. We
recommend that any adjustments, other
than those above, be done by a qualified
repair technician.
Tubular plate vial
A. Place the plate vial parallel to the
leveling screws, A and B. Center the
bubble using these two level screws.
B. Turn the instrument 90° and center
the bubble using leveling screw C.
C. Return to the original position in step
A. Recheck the bubble and center as
necessary. Rotate the instrument 180°.
The bubble should still be centered in
the vial. If not, go to next step.
D. Using the adjusting pin, provided
in the case, turn the screw until the
bubble moves halfway back to its
original position.
E. Return the instrument to its original
position and repeat steps A through
C. Repeat these steps until the
bubble stays centered in all positions.

-16-
Circular Leveling Vial
If the circular vial is centered after leveling
the plate vial, then no further adjustment
is necessary. If not, proceed with the
following adjustment.
A. Using the adjusting pin, provided in
the case, turn the adjusting screws
until the bubble is centered in the vial.
Do not over tighten the adjusting screws
B. Loosen one screw by turning it 1/4
turn, then tighten the other screw by
1/4 turn.
Optical Plummet
This adjustment is required to make
the line of sight of the optical plummet
coincide with the vertical axis.
A. Point the optical plummet at a ground
target. This can be done by adjusting
the level screws or by loosening
the instrument fastening screw and
moving the instrument over the
target.
B. Turn the instrument 180° and
re-sight the target through the optical
plummet. If the target is still centered,
no adjustment is necessary. If not, go
to next step.
D. Using the adjusting pin, provided in
the case, turn the reticle adjusting
screws until half the displacement has
been removed. Loosen one screw
1/4 turn, then tighten the opposing
screw 1/4 turn.

E. Repeat steps A through D until there
is no displacement of the target when
the instrument is turned about its
vertical axis.
Collimation Error
• Attach the instrument on a tripod and
precisely level.
• Aim at point A in the distance with the
normal, direct position of telescope.
Record the reading of the horizontal
angle - HR-DIRECT.
• Using the reverse position of the
telescope, take the reading of the
horizontal angle - HR-REVERSE, then:
Collimation Error C = (HR-Direct -—
HR-Reverse ± 180°)/2
If C <10”, no adjustment is required.
If C >10”, the following adjustment is
required:
• Adjust the horizontal fine motion in
the reverse position of the telescope
so that the reverse reading HR-Rev =
HR-Rev + C.
• Remove the protective cover of the
reticule of the telescope and adjust
both the left and right adjusting
screws so that the vertical hair of the
reticule coincides with object A.
• Repeat the steps until acceptable
condition is reached.

-17-
Index Error of Vertical Circle
• Attach the instrument on a tripod and precisely level.
• Aim at any object, point P, in the normal position and
take the reading of vertical angle - V-Direct.
• Turn the telescope to the reverse position and aim it at
point P again. Take the reading of other vertical angle -
V-Rev.
If (V-Direct + V-Rev) - 360°= ≤15”, no adjustment is required.
