2.1.2 Reflector
When measuring distance, a reflector prism needs to be placed at the target place.
Reflector systems come with single prism and triple prisms, which can be mounted with
tribrach onto a tripod or mounted onto a prism pole. Reflector systems can be
self-configured by users according to job.
2.1.3 Tribrach
Use the straight screwdriver to loosen the fix screw on the tribrach, with 180°anti-clock
wise direction. Then pull out the equipment.

2.1.4 System Information
Hold the power key in 1s to power on. The initial page is the angle measurement mode (a),
press to enter the system information page (b). Press [3] Information to
check the hardware information.
Hold the power key in 4s to power off.
2.1.5 Initial Settings
Mount the instrument to the tripod. Level and center the instrument precisely to
ensure the best performance.
Operation Reference:
1. Leveling and Centering the Instrument by plumb bob
1) Setting up the tripod
① First of all, extend the extension legs to suitable length, make the tripod head
parallel to the ground and tighten the screws.
② Make the centre of the tripod and the occupied point approximately on the same
plumb line.
③ Step on the tripod to make sure whether it is well stationed on the ground.
2) Attaching the instrument on the tripod
Place the instrument carefully on the tripod head and slide the instrument by
loosening the tripod screw. If the plumb bob is positioned right over the center of the
point, slightly tighten the tripod.
3) Roughly leveling the instrument by using the circular vial
① Turn the leveling screw A and B to move the bubble in the circular vial, in which
case the bubble is located on a line perpendicular to a line running through the centers

8
of the two leveling screw being adjusted .
② Turn the leveling screw C to move the bubble to the center of the circular vial.
4) Precisely leveling by using the plate vial
① Rotate the instrument horizontally by loosening the Horizontal Clamp Screw and
place the plate vial parallel to the line connecting leveling screw A and B, and then
bring the bubble to the center of the plate vial by turning the leveling screws A and B.
② Rotate the instrument 90º(100g) around its vertical axis and turn the remaining
leveling screw or leveling C to center the bubble once more.

9
③Repeat the steps ①② for each 90º(100g) rotation of the instrument and check
whether the bubble is correctly centered in all directions.
2. Centering by using the optical plummet
1) Set tripod
Lift tripod to suitable height, ensure equal length of three legs, spread and make
tripod head parallel to the ground, and place it right above the measurement station point.
Prop up tripod on the ground and fix one leg.
2) Install instrument and collimate the point
Set instrument carefully on tripod, tighten the central connecting screw and adjust
optical plummet to make the reticle distinctly. Hold the other two unfixed legs with both
hands and adjust position of these two legs through observation of optical plummet. As it
approximately aims at the station point, make all three legs fixed on the ground. Adjust
three leg screws of the instrument to make optical plummet collimate precisely to the
station point.
3) Use circular vial to roughly level the instrument.
Adjust length of three legs of tripod; make the circular vial bubble of the instrument in
the middle.
4) Use plate vial to level the instrument accurately.
① Rotate the instrument horizontally by loosening the Horizontal Clamp Screw and
place the plate vial parallel to the line connecting leveling screw A and B, and then
bring the bubble to the center of the plate vial by turning the leveling screws A and B.
② Rotate the instrument 90℃, make it perpendicular to the connecting line of level
screws A and B. Turn level screw C to make the bubble of the plate vial in the middle.
5) Precisely centering and leveling
Through observation of optical plummet, slightly loosen the central connecting screw and
move the instrument evenly (Don’t rotate the instrument), making the instrument
precisely aim to the station point. Then tighten the central connecting screw and level the

10
instrument precisely again.
Repeat this operation till the instrument collimate precisely to the measurement station
point.
2.1.6 Star Key
Press to activate the Star Key menu, press direction key / / / to move
the cursor, press function keys to operate. Press to exit the menu.
(1) Direction keys
Reflector: the default setting is NON-P. Press to switch among Prism, Sheet and
Non-prism mode.
Plummet: the intensity for laser plummet. Press to switch the value among 2→1
→0→4→3→2, 0 means off.
Contrast: the default value is 10. Press to switch the contrast for LCD screen
among 10→11→……→16→00→01→02……→09→10.
CrosHair: Illumination for crosshair. The default value is 0. Press to switch the
value among 0→1→2→3→4→0, 0 means off.
(2) Function keys
ILL: Illumination for LCD screen and keyboard. The default setting is on. Press F1 to
open or close the illumination.
TILT: On/Off the tilt sensor. The default setting is dual-axis sensor. Press F2 to enter 1/2
page. Then press X-ON for single X-axis compensation, press F2 XYON for dual-axis
compensation. Press F3 OFF to close the compensator. Press F4 to enter 2/2 page. It
will display the compensate value on current position.
Point: On/off laser pointer. The default setting is off. Press F3 to switch the laser

11
pointer between on and off.
PARA: Parameter setting menu.
Input the value of temperature and atmosphere pressure. It will calculate the PPM
automatically based on the atmosphere correction.
Reference value: Temperature 20℃,pressure P=1013hPa
Calculation formula:
t
P
003661.01
294922.0
44.278PPM


Users can also calculate the PPM value based on the formula by themselves and input
the value by manual.
Note: a) Input range for temperature :-30℃~+60℃, min. 0.1℃increase; Input range
for atmosphere pressure560~1066hPa, min.0.1hPa increase. B) Input range for PPM is
-999.9~999.9ppm.
(3) Reflecting Signal
When the deviation among line of sight and emitting & receiving axis is over-range, please
adjust the emitting axis to the prism center.
Press to select Prism mode, press F4 PARA then aim at the target center. It
will show the intensity of signal by a column. The default prism constant is -30mm. Adjust
the horizontal tangent unit or telescope focusing ring, the emitting axis will focus precisely
to the target center when the reflecting signal reaches the maximum value.

2.2 Angle Measurement
Press to power on the equipment, N6 will enter
the angle measurement mode automatically. If the
current mode is distance or coordinate
measurement mode, press to switch to angle
measurement mode.
2.2.1 Function Menu in Page 1
2.2.1.1 ALL
ALL means measuring and saving. If the user need to change the current file or create a
new file as the current file, please press FILE on page 3 at first.
When creating a new file, the equipment will create the .SMD and .SCD file under the
same name automatically. SMD means South Measure Data, is used for record the data of
horizontal disk, vertical disk and SD. SCD means South Coordinate Data, is used for record
3D coordinate for measured points.
