2. OPERATION
2.1 Preparation
Unpacking
Lay down the case lightly with the cover upward. Unlock the case, and
take out the instrument.
Storage of Instrument
Cover the cap, put the instrument into the case with the vertical clamp
screw tightened and circular vial upwards (lens towards tribrach).
2.2 Instrument Setup
1) Setting up the tripod
A. Loosen the screws on the tripod legs, pull out to the required length
and tighten the screws.
B. Make the center of tripod and the occupied point approximately on
the same plumb line.
C. Step on the tripod to make sure if it is well stationed on the ground.
2) Instrument setup (Laser plummet)
A. Place and fix the instrument carefully on the tripod
B. Press [★]and select [7]LaserPlt to turn on the laser plummet. Hold the
two legs which are not fixed on the ground and decide the position to
fix according to the laser dot. When the laser dot is roughly on the
station point, fix those 2 legs.

9
Instrument setup (Optical plummet)
Adjust the eyepiece of the optical plummet telescope to your eyesight.
Slide the instrument by loosening the tripod screw; place the point on
the center mark of the optical plummet. Sliding the instrument carefully
as to not rotate the axis will allow you to get the least dislocation of the
bubble.
3) Roughly leveling by the circular vial
A. Rotate the foot-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 of the two leveling
screw being adjusted .
B. Rotate the foot-screw C to move the bubble to the center of the
circular vial.
4) Leveling by the plate vial
A. Rotate the instrument horizontally by
loosening the horizontal clamp unit
and place the plate vial parallel to the
line connecting rotating the foot-screw
A and B, and then bring the bubble to
the center of the plate vial by rotating
the foot-screw A and B.
B. Rotate the instrument in 90º(100gon)
around its vertical axis and turn the
remaining leveling screw or leveling C

10
to center the bubble once more.
C. Repeat the steps and check whether the bubble is correctly
centered in all directions.
If the laser or optical plummet doesn’t stay at the center position after
levelling, please slightly loosen the screw under the tripod head and
move the instrument (don’t rotate the instrument) until the equipment is
on the station point. Tighten the screw and level the instrument again.
Repeat these steps until the instrument is precisely centered and
leveled.
Note:
You can also level the instrument precisely by the E-bubble.
When the tilt is over ±4’, the system will enter the adjusting page of tilt
sensor automatically.
2.3 Battery
Inserting
Put the battery into the instrument, push it. Check and insert it correctly
to side into the housing.
Replacing
Press the battery lock on both sides, remove the battery. When the
remaining voltage is less than one grid, please stop your operation and
charge it as soon as possible.
Before remove the battery from the instrument, make sure that the
power is turned off. Otherwise, the instrument may be damaged.

11
Charging
The battery must be charged prior to using before the first time
operation.
The battery LI-39 should be charged only by the official charger NC-III,
which packed together with the instrument. Please connect the power
supply in 220V, among 0°~±45°C.
When the indicator on the charger is red, the charging process has
begun. When indicator turns green, the charging has finished. For
safety, please pull out the battery and charger in time.
In order to get the maximum service life, please charge the battery at
least once in a month.
Note:
a) The operating time depends on the outside conditions, such as
ambient temperature, charging time, the cycles of charging, etc. It
is recommended for safety to charge the battery beforehand or to
prepare spare full-charged batteries.
b) The remaining voltage of battery shows the power regarding to the
current measure mode. The consumption of distance
measurement is higher than angle measurement in normal. When
switching the measurement mode from angle to distance in a low
battery voltage, the equipment might be interrupted.
2.4 Tribrach
Dismounting
If necessary, the instrument can be dismounted from tribrach. Turn the
locking knob in 180° counter-clockwise to disengage anchor jaws,

12
and take off the instrument.
Mounting
Insert three anchor jaws into holes of
tribrach and line up the directing stub.
Turn the locking knob about 180°
clockwise to mounting the instrument.
2.5 Eyepiece Focusing
Sight the Telescope to bright place and rotate the eyepiece tube to
make the reticle clear. Roughly collimate the target by the top of the
triangle mark on EDM cover.
Rotate the focusing screw on eyepiece to make the image clear.
2.6 Input Mode
Swift the input mode between numbers
and alphabets by [Shift] on keyboard or
[123]/[abc] on soft-keypad.
Swift the case of alphabets by [α] on
keyboard.
