PRECAUTIONS
Before using this instrument, please make sure that each function is running well.
●Avoid to make the surface of the digital staff as well as the joints between each
section dirty or damaged, otherwise it will influence on the accuracy of reading and
measurement. This is because the instrument needs to transfer the black & white bar
code to electric signal. That’s why in case the digital staff is dirty, the accuracy would
be descended, or even the instrument is not able to measure.
●Tripod
The digital level should be mounted on wooden tripod. Metal tripod is lighter and
shack easily, which will affect the accuracy. Each leg of the tripod should be fixed well
by screws.
●Tribrach
Please check the adjusting screw on the tribrach frequently, do make sure the central
fixing screw is tightened.
●Packing well to avoid the instrument shaked
The digital level should be handled carefully to avoid shaking and crashing during
transportation. Severe shaking would damage the measurement functions. When
packing the instrument in the case, make sure the instrument is power off and take off
the battery too.
●Carry the instrument carefully
When you need to move the instrument, you must grasp the lifting handle and take it
off from the tripod.
●Avoid to expose the instrument in sun, rain or humid condition
Leaving the instrument in place of high temperature (+50℃) would damage the
instrument. Do not shoot the sun with the objective len; otherwise the spare parts
inside the instrument may be damaged.
●Avoid the great change of temperature
A great change on instrument temperature would descend the measuring range. For
example, when the instrument is moved out from a hot car, please leave the
instrument to adapt to the surrounding temperature before use.
●Battery Inspection
Check the remaining battery before use.

2. PREPARATION FOR MEASUREMENT
2.1 Mounting the Instrument
Placing the Tripod.
Type E aluminum tripod with flat or dome head tripod is required.
(1) Adjust the three legs of the tripod to a proper length and tighten the fixing screws
at the middle of the leg.
(2) Tighten the hexagonal nut on the head of the tripod in order to make the tripod
legs not too loosen. Place the tripod on a certain point, expand the legs until the
distance between each leg is about 1m. First, fix a leg, and move the other 2 legs to
make the head of the tripod approximately leveled. If necessary, adjust the length of
the tripod legs.
(3) Trample the legs into the earth or fix it well on the ground.
Mount the Instrument on the Head of the Tripod.
Take out the instrument carefully and place it on the head of the tripod.
(1) Aim the tripod central screw to the center of the tribrach and tighten the screw
until it is fixed at the head of the tripod.
(2) If you need to define an angle or a line through the horizontal dial, you should
center the instrument precisely with a plummet.
(3) Center the circular bubble by adjusting the three leveling screws of the tribrach. If
you are using a dome headed tripod, you should slightly loosen the tripod central
screw and rotate the instrument round the head of the tripod until the circular bubble
is centered, then tighten the screw.
Mounting the Instrument on a Certain Point (centering)
If you need to measure an angle or alignment, please precisely center the instrument
at a certain point with the plummet.
(1) Hang the plummet at the plummet hook of the central screw of the tripod.
(2) Adjust the plummet line to a proper height.
(3) In case the instrument is not centered at the known point, you can move the
instrument to that point without changing the position relationship between the
tripod leg and its head. First, put the tripod on the known point approximately until

14
the plummet is about 1cm away from the point. Second, grasp two legs of the tripod
and adjust the tripod by the third leg until the head of tripod is leveled approximately
with a proper height. Expand the legs of the tripod and fix it on the ground.
(4) Finally, observe the plummet and the hook and trample the legs into the ground.
(5) Slightly loosen the central screw of the tripod and move the instrument on the
head until the plummet is centered at the known point. Tighten the tripod central
screw.
Leveling the Instrument
Center the circular bubble by adjusting the tribrach screw.
First, put the tribrach as the below picture shown. Rotate 2 screws at the same time in
opposite direction until the bubble moves to a position where the line between the
bubble and screw C is perpendicular to the line between screw A and B (refer to
Picture A). Then rotate the screw C to move the bubble to the center of the central
circle. This procedure should be repeated for times until the bubble is centered on any
directions. While leveling, remember the “Left Thumb Principle” which means that the
moving direction of the bubble is the same as that of the left thumb. Do not rotate the
leveling screw without thinking.
Notice: Do not touch the telescope during leveling.
Collimating and Focusing
(1) Sight at the digital staff with the rough collimator.
(2) Rotate the eyepiece slowly until the image of the crosshair becomes clear.
(3) Rotate the focusing hand wheel until the image of digital staff becomes clear.
Rotate the horizontal tangent to move the image of the staff to the center of the

15
vertical hair of the crosshair.
(4) Observe through the eyepiece. Move your eye slightly up, down, left and right to
check whether the relative position between the crosshair and the image of the staff is
not changed. If not, please return to step 1.
Notice: Measurement accuracy may be influenced if the crosshair and focusing is not
clear.
2.2 Power On
Press the power key (POW/MEAS).
