• 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.

Measurement of Vertical Angle
• 0° angle position can be set as follows in the initial setting:
ZEN==90 (Zenith 90°)
0°
90°
180°
270°
ZEN==0 (Zenith 0°)

Compensation of the Tilt Sensor to
Vertical Angle.
• If the instrument is inclined within ±3’,
the tilt sensor can compensate the vertical
angle. If the inclination is greater than ±3’,
the instrument will display [TILT] as
shown in the figure.
Display of slope
• Press [V/%] button, the vertical angle
display is changed to slope display; press
[V/%] button, the vertical angle display is
resumed.
Note: When vertical angle is converted to
slope, the precision of the slope reading is
two digits after the decimal. The value of
slope is displayed only within ± 45°
(100%). There will be no slope display
exceeding this range.

Measurement of Horizontal Angle
• Reset of Horizontal Angle
Press [0SET] button, the horizontal angle
returns to zero
Selecting the Direction of Measurement of
Horizontal Angle.
• Press [R/L] button to change the
direction of measurement of the horizontal
angle.
When “HR’ is displayed, the angle
increases with clockwise turning.
When “HL” is displayed, the angle
increases with counterclockwise turning.
Holding Horizontal Angle.
• Press [HOLD] button, the horizontal
angle will be held. The reading of the
horizontal angle will remain unchanged
even if the direction of telescope is
changed. Press [HOLD] button again, the
hold of horizontal angle is released.

Measuring Distance Using the Stadia Method
Read the leveling rod using the stadia hair on the reticule of the telescope. Multiply the
reading by 100, to obtain the actual distance L from the target to the measured point.
(100 is the multiplication constant error of the instrument, i.e., L = l x 100)

Installation and Removal of the Base
Base Removal
• Turn the screw on the Tribrach Locking Lever outward using a flat screw driver to its stop.
• Turn Tribrach Locking Lever 180° counterclockwise. Holding the base with one hand,
take the main body off the base.
Base Installation
• Turn the Tribrach Locking Knob 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 clockwise until it reaches the position limit so that the
‘v’ mark points downward. Turn the locking screw inward until it hits its stop.
INSPECTION
Tubular vial
• Attach the instrument to a tripod and rough level. Position the tubular vial parallel to a
line connecting any two of the three leveling screws on the base. Adjust the two leveling
screws so that the tubular bubble is centered.
• Turn the instrument 180° and check if the bubble remains at the center.
• If the bubble remains at the center, no adjustment is required. Otherwise, perform
adjustments as follows:
• Using the bubble adjustment screws, move the bubble towards the tube center for half of
the error
• Turn the leveling screw to correct the other half of the error so that the bubble is
centered.
• Rotate the instrument 180 degrees and check if the bubble remains centered. If the
bubble is centered, the adjustment is complete. If not, repeat the steps until the bubble is
centered when the instrument is at any position.
Circle vial
After making sure that the tubular vial is correctly adjusted, check the circular level. If the
bubble is centered, no adjustment is required. Otherwise, adjust the three adjustment
screws with a needle to center the bubble.
Optical Plummet
• Attach the theodolite to a tripod (no leveling is required).
• Place a target under the instrument.
• Focus the image of the target then adjust the leveling screws so that the target is centered
in the reticule.
• Turn the instrument 180°.
• If the target remains at the center of the reticule, no adjustment is required. Otherwise,
adjust as follows.
• Unscrew the optical plummet protective cover ring
• Using the adjustment screws for the reticule, reduce the off—center distance by half.
Note: use the needle (as shown below).
• Repeat the above steps until the target coincides with the center.
Perpendicularity of Vertical Crosshair of Reticule of Telescope
• Attach the instrument on a tripod and precisely level
• Place a target point, A, 50M away from instrument.
• Aim the telescope at point A. Move the telescope using the vertical fine movement. If
point A moves along the vertical hair of the reticule, no adjustment is required.
Perform the following adjustment if the point A strays from the vertical crosshair:
• Remove the protective cover of the reticule and slightly loosen the four adjusting screws.
Turn the assembly so that point A coincides with the vertical hair, retighten the four
adjusting screws.
Repeat the above steps until there is no error.

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. Next 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.
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. Otherwise, perform
adjustment as follows:
Press and hold [R/L] + [HOLD] buttons
while pressing [ON/OFF] button.
Release [ON/OFF] button when full
character display appears and then release
[R/L] + [HOLD] buttons when four
beeps are heard.
Swing the telescope near horizontal with
the instrument in the normal position.
Allow the vertical angle to reset after it
crosses zero. Aim the telescope in the
normal position at object P and press
[0SET] to confirm.
Aim the telescope in the reverse position
at object P and press [0SET] to confirm.
With this, the compensation of index
error is completed.

Display Meaning and remedy
E01 Count error, if displayed repeatedly, repair is needed
TOO FAST
The telescope or collimation unit rotated too fast, press any key
except [on/off ] and [
], the instrument returns to normal state
E04 Horizontal sensor I error, repair is needed.
E05 Horizontal sensor II error, repair is needed.
E06 Vertical sensor error, repair is needed.
TILT
The tilt sensor is out of range. Level the instrument again. If this
does not clear the error code, repair is needed. Note: For a
temporary solution, the tilt sensor can be turned off.
