Precaution
1. Avoid heavy shock
For long-distance transportation, pay attention to external
package and shock proof.
2. Setting and moving
When placing the instrument on the tripod head, hold the
instrument and rotate the tripod screw until it is fixed securely
on top of the tripod head. Repeat the above mentioned
procedure for removing the instrument from tripod head. If the
instrument must be carried with tripod attached, never carry
it horizontally over the shoulder, always keep it in vertical
direction when carried. The instrument must be kept in
container for long-distance transportation.
3. Keep it clean
Clean dust of the instrument surface with cotton wool or small
brush after using the instrument. Dry the instrument on time
after it exposed in the rain. Make sure not to use chemicals
to clean battery case and plastic parts. If necessary, damp soft
cloth is permissible. High aborbent cotton and lens-cleaning
paper are used for exposed optics. Never use handkerchief
and clothes.
4. Avoid the long-time irradiation
Never leave the instrument in extreme heat longer than
necessary. It could adversely affect its performance.
5. Check the battery
Be sure to check the battery for voltage level before use.
6. Notice
Store the instrument in a place with good air circulation and
low humidity. Temperature is kept under 45 C. Often change
drier in the instrument container.

4. Preparative before measurement
4.1 Level the instrument
Level and center the instrument correctly to ensure the best
performance.

4.1.1. Place the tripod
First, put the tripod leg in the proper position and tighten the
locking screws.
4.1.2. Attaching the instrument to the tripod head
Place the instrument carefully on the tripod head, and move
the instrument slowly by loosening adjusting screw. Align the
plumb bob with the point on the ground when aligned, tighten
the adjusting screw.
4.1.3. Initial rough leveling the instrument with circular level
a. Use leveling screws 1, 2 to move the bubble of the circular
level until the bubble of the circular level is located on a line
perpendicular to a line running through the centers of the
two leveling screw adjusted.
b. Revolve the leveling screw 3 to shift the bubble to the center
of the circular.
6
4.1.4 Further leveling the instrument with plate level
a. Loose horizontal motion clamp and revolve the instrument.
By adjusting leveling screw 1, 2, the plate level vial is parallel
to a line running through the centers of two leveling screws,
and place the bubble in the center of the level vial.
b. Next, revolve the instrument 90 (100g) around its vertical
axis and use the remaining screw 3 to center the bubble
once more.
o
bubble bubble

c. Repeat the above procedure for each 90 revolution of the
instrument and check whether the level bubble is correctly
centered for all points.
4.1.5. Centering the instrument with optical plummet
Adjust the eyepiece of the optical plummet telescope to the
user’s eyesight. Move the instrument by loosening with the
center mark of the optical plummet telescope. Carefully move
the instrument in order to make it steady.
4.1.6. Final leveling of the instrument
Repeat procedure of 4, and check whether the level bubble is
in the center of the level vial. Finally tighter adjusting screw.
4.2 Power switch on
1. Press , all segments of display with light on. The display
shows that vertical angle should be sent to zero.
2. Rotate the telescope to set the instrument to a vertical angle
reading of 0.
3. Press over 2 seconds, it can be power off.

Measuring distance with the cross-hair in telescope reticle is
another application of the theodolite series products. This is
a simple method, but scale station pole is needed, for example,
horizontal measuring staff and apparent distance staff. By view
-ing through the telescope, the length between upper and lower
stadia hairs multiplied by 100 is the distance from the instrument
to the station pole(the length refers to the reading from station
pole between two stadia hairs).
10. Other function
10.1 Measuring distance
1. First fix the station pole at the measuring point.
2. Level instrument.By viewing through the telescope, make
sure the reading between two stadia lines.
3. The distance from instrument plumb bob center to station
staff “L” is 100 times of “I”, L=100 x I.

10.2 Tilt correction function
This instrument provide vertical axis incline compensator. It can
compensate the cline angle automatically. When the incline sensor
is switched on, the instrument can detect the vertical axis incline
angle. When instrument inclines over the compensator range,
it displays “TILT”. You should level the instrument manually.
