ANGLE MEASUREMENT
NORMAL/REVERSED POSITION TELESCOPE
“Normal position telescope” means that the shaft disc is on the left side of the telescope
when observers face eyepiece lens. “Reversed position telescope” means that the shaft
disc is on the right side of the telescope when observers face eyepiece lens.
Averaging the value of normal/reversed position can effectively eliminate the instrument
systematic errors. So when measure angle,please rotate telescope 180° and observe
with reversed position telescope after observing with normal position telescope.
HORIZONTAL ANGLE “0” SETTING
Sight the telescope at object A, press , set the horizontal angle reading as
0°00’00”.
Note: The key is valid only for horizontal angle. Horizontal angle can be set to 0 at
any time except when key is locked.

HORIZONTAL AND VERTICAL ANGLE MEASUREMENT
Set the mode for horizontal right, Press to change horizontal angle from right to left
mode.
• If display left,turn the alidade at clockwise to add horizontal angle.
• If display left,turn the alidade at counterclockwise to add horizontal angle.
Choosing left and right measuring style are decided by observers preference.
Vertical angle measurement setting
There are two way of measuring vertical angle: zenith 0 degree and 90 degrees
Measurement
Sight target 1 with cross line centered
Press , horizontal angle setting of target 1 is 0°00’00”
Turning clockwise, sight target 2 with cross line center, horizontal angle between target
1 and 2 (turning right) will be displayed.
Example:
Press
Sight Target 1
Vertical angle of target 1 (zenith distance)
Horizontal angle of target 1 has been set to 0
Choose the direction of the horizontal angle measurement, sight target 2
Vertical angle of target 2 (zenith distance)
Horizontal angle, right turning direction
target 1 has been set to 0

12
Press , choose right, turn telescope at counterclockwise, then sight target 1 with
cross line center. Press ,horizontal angle of Target 1 turn to be “0” position, then
sight target 2 with cross line center,display horizontal angle between 1 and 2 (turning
left).
Rotate telescope 180 degree, repeat steps.
Horizontal angle lock and release
In the procedure of horizontal angle observation, if you want to retain the measured
value,press .“left, right, horizontal” characters icker at lower left of the display and
the horizontal angle value will not change even if you rotate the instrument when you
sight at any direction.
Press again to release lock function.
Note: lock and release of is only valid for horizontal angle.
Horizontal angle quadrant setting
Sight at the rst object and then press to set the horizontal angle to zero.
Turn the instrument around the vertical axis until the beep starts, displaying
.
Lock the instrument by the clamp screw and set the horizontal angle to 90° 00’ 00” by
the tangent screw. Then, x the quadrant target direction by the telescope reticule.
Repeat to setting quadrant target point of 180°, 270°. The buzzer beeps when the read-
ing passes any of 0°, 90°, 180°, 270°.
Note: The beep can be canceled when we do initial setting.

www.SitePro.us.com 13
Vertical angle “0” setting
In initial setting, vertical“0”setting is zenith 0°/horizontal 0°.
ZEN=0 (zenith 0°) ZEN=90 (zenith 90°)
Measurement of zenith distance and vertical angle
Zenith Distance
If vertical angle is 0° for zenith direction, the vertical angle measured in this way is the
zenith distance.
Zenith (0° 00’ 00”)
Horizontal direction (90° 00’ 00”)
Zenith distance: Q = (L+360°-R) /2
Index difference: I = (L+R-360°) /2

Vertical Angle
If vertical angle is 0° in horizontal direction, then, the vertical angle measured in this way
is the perpendicular angle.
Note: If index difference ‘I’ ≥ 10”, adjustment should be made as 8.6.
Gradient percentage
The vertical angle can be converted into gradient percentage in angle measurement
mode.
The range of gradient is from horizontal direction to ±45° (except 45°). Otherwise the
instrument will not display the grade percentage.
Method: Press until two beeps, the display panel shows vertical angle or gradient
percentage alternately.

DISTANCE MEASUREMENT
Distance measurement with stadia hair of the telescope
The distance from the measuring object to the instrument can be obtained by using
the stadia hair (up and down or left and right) of the telescope, with the accuracy of
≤0.4%L(L: the distance of the target).
Measurement methods:
1. Set up the instrument at point A and put the surveying rod on point B.
2. Read the intercept of apparent lines from up and down(or left and right) from the
reticule on the survey rod.
3. The horizontal distance (L) between A and B equals L=a×l00.
INSPECTION AND ADJUSTMENT
Let the plate vial be in parallel with a line joining any two of leveling screws. Adjust the
two leveling screws and position the bubble in the center of the vial by turning the screws
in opposite directions at the same time.
Rotate the instrument 180°. If the bubble is in the center and always in the center while
the plate vial is moved to any directions, the plate vial is set correctly and the instrument
is leveled.
Adjustment
Leveling with plate vial, bring it half way back to the center by adjusting the leveling
screw which is parallel to the plate vial.
Correcting the remaining half by adjusting the bubble adjusting screws with the adjusting
pin.
Conrm that the bubble does not move from the center when the instrument is rotated
by 180°.If not,repeat above steps.
Turn the instrument around 90°and adjust the third screw to center the bubble in the
vial. Repeat inspection and adjustment steps until the bubble remains in center in any
directions.

16
Circular vial
Ajustment is unnecessary if the bubble of the circular vial is in the center after inspection
and adjustment of the plate vial. If not,it is necessary.
If the bubble of the circular vial is not in the center, bring the bubble to the center by us-
ing adjusting pin or adjustable wrench to adjust the bubble adjusting screw.
When adjusting, rst loosen the screw on the Opposite of the offset side, then, tighten
the adjusting screw on the offset side, bring it to the center.
After the bubble stays in the center, keep the fastening strength of the three screws in
uniformity.
Reticule gradient of telescope
Fix the instrument on tripod and level. Sight at an object A, approximately 50m far from
instrument, through the telescope and lock the horizontal and vertical clamp screws.
Move point A to the edge of the eld of view by the vertical tangent screw. No adjust-
ment is necessary if point A moves along the vertical line of the reticule.
If the point A does not move along the vertical line, rst, remove the reticule cover
between eyepiece and focusing screw, and you can see the four screws.
Loosen the four reticule adjusting screws uniformly with an adjusting pin. Rotate the reti-
cule around the aiming axis, and align the vertical line of the reticule with point A.Tighten
the reticule adjusting screw uniformly.
Repeat the inspection and adjustment to check that if the adjustment is correct.
Cover the reticule cover back.

Perpendicularity of aiming axis to horizontal axis(2C)
Fix the instrument on tripod and level. Sight at the object A in normal position (left or
right ways turning are all acceptable,just keep in same way during inspecting,and please
not press ) and read the horizontal angle left1.
Loosen vertical and horizontal clamp screws, and reverse the telescope. Sight at the
object A in reversed position and read the horizontal angle value left2
So: 2C = left1-(left2180°)
If |2C| < 16”, needless to adjust.
If |2C| ≥ 16”, need to adjust.
In the inverted position rotate at mirror micro hand wheel so that the inverted mirror
reading
Left2 = left2+C
Take down the cover of the reticule. Adjust the two adjusting screws by loosening one
and tightening the other. Move the reticule to sight at the object A exactly.
Repeat inspection and adjustment until | 2C | <16”. Cover the cover of reticule back.
Vertical index zero compensation
The instrument with vertical disc which be equipped with auto compensation and zero-
storing device,please make inspection as follows:
After precisely leveling the instrument,make the direction of telescope coincide with the
line between center of instrument and screw of any tripod leg (setting as M),then tight
the horizontal clamping knob.
Turn power on,sight at target A and tight the vertical clamping knob,then instrument will
display the vertical angle.
Rotate the screw M slowly in one direction until it gets about 10mm and the instrument
display “TILT”,it means the vertical incline has been out of compensation range.
Then rotate the screw M in the opposite direction,the instrument is operating smoothly if
vertical angle is redisplayed,otherwise, the compensator is abnormal or failure.
The adjustment of the compensator is complicated, please send it to factory for repairing
if it is abnormal or failure.

18
Vertical index difference and vertical index zeroing
Note:After making adjustments make the inspection as following:
Leveling the instrument and turn the power on. Then, sight at a reference A with normal
position telescope and obtain the vertical angle (L).
Reverse the telescope and sight at the object A again and obtain the vertical angle (R).
• If vertical angle is zero at zenith, then, vertical index difference I = (L+R-360°) / 2
• If vertical angle is zero at horizontal, then, I = (L+R-360°) / 2 or (L+R-540°) / 2.
• If | I| ≥ l0”, vertical index zeroing should be set again.
After leveling the instrument, press + key and ,release when display charac-
ters and release + until three beeps,The instrument displays:
In normal position, Sight at a clear and stable object A , which is nearly the same height
as the instrument, turn the telescope around near the horizontal direction until vertical
angle of A appears. Press key, displaying FACE-2.
Reverse the telescope and sight at the object A again. Press key to nish vertical
index zeroing setting. The instrument returns to angle measurement mode.
Repeat the inspection procedure until index difference (I) meet the requirement, If the
vertical index difference does not meet the standard yet after being adjusted repeatedly,
the instrument should be sent to factory to be repaired.
