4. CARE AND MAINTENANCE
Misapplication or negligence of the terms of service instruction can cause damage effect to your health.
•
Avoid excessive vibration and shocks! Store the instrument and it’s accessories only in carrying case.
•
Optical level-is an accurate instrument, which should be stored and used with care.
•
In high humidity and temperature you should dry out the instrument and clean it after usage.
•
Do not store the instrument at a temperature below -25ºC and above 50ºC, otherwise the instrument can be out of
•
action.
Do not put the instrument into the carrying case if the instrument or case are wet. To avoid moisture condensation
•
inside the instrument- dry out the case and the instrument.
Check regularly instrument adjustment!
•
Keep the lens clean and dry. To clean the lens use soft cotton cloth.
•
Never place the instrument on the ground.
•
If you leave the instrument on the tripod, close the lens with cover and cover the instrument.
•
For cleaning plastic case use neutral detergents or water. Don’t wipe the case with dissolvent.
•
When you put your level into the case, place all accessories on their places,
•
5. PREPARATION BEFORE STARTING TO WORK
5.1. SET UP THE INSTRUMENT
1) Untie the belt around tripod legs and untwist clamping screws (Pic.1)
2) Without setting up the tripod, stretch out the legs till the tripod head will be at eye
level. Then tighten clamping screws.
3) The distance between legs should be equal to the equilateral triangle.

Pic.1

4) Tripod head should be placed horizontally. Fix the end parts of tripod legs,
plunging them into the ground (Pic.2)
5) Tighten retaining bolt, holding the instrument on the tripod (Pic.3).
6) When you use the tripod with spherical head, loosen slightly retaining bolt.
Holding with both hands the instrument with support (6), move the instrument along the tripod head to make the bubble into the center of the circular
level (8) (Pic.4).
7) Tighten retaining bolt.
8) With the help of leveling screws (5) make the bubble directly into the
center of the circle level (Pic.5)

5.2. FOCUSING AND SURVEYING
1) Point the instrument at bright uniform background.
2) Rotate clockwise the ocular ring up to the stop. After that look into the ocular of the telescope and focus the view of
reticule, slightly rotating anticlockwise the ocular ring. You should stop rotating when the view of reticule will be clear. You
shouldn’t repeat this procedure very often.
3) Point the instrument at the staff with the help of front sight (13). Then, with rotation of the knob (4) place the staff in the
center of eyesight. Remove parallax* between the staff and reticule while rotating rack-and-pinion (7).
*Parallax removal
There is no parallax, when the object view and reticule view are xed to each other even if we change eye position to the
ocular. Parallax can cause big measurement errors. That’s why you should remove it with the help of rotating rack-andpinion (7).
5.3. CIRCULAR LEVEL
1) With leveling screws (5) make the bubble into the center of circular level (2).
2) Rotate the instrument through a full 180˚ (pic.6).

MEASUREMENT FOUNDATION
RUBER-X32
The bubble should be in the center. If it is shifted from the center, follow the instruction:
3) Remove only half of the bubble shift with leveling screws (5) (Pic.7)
4) Remove the remaining half of the bubble shift with rotation of adjusting screws of the level with the
hex-nut wrench (Pic.8).
5) Repeat these actions till the bubble shift will remove completely.
Pic.7 Pic.8
5.4. AUTOMATIC COMPENSATOR
1) Make the bubble into the center of circular level.
2) Point at clear object. Then rotate leveling screw on 1/8 rotation to the right and to the left,
check the shift of the horizontal reticule to the object. Stadia hair should twitch and back to
the previous place.
It is recommended to check the instrument action every time before working.
Note: Level ADA Ruber x32 is equipped with clamp (14) for xation of the level during transportation in the case.

There is another way to check the compensator.
Make the bubble into the center of circular level.
When you see clear object, hit slightly the tripod legs or the instrument case. Horizontal line should twitch slightly and
back to the previous place.
5.5. RETICULE
1) Set up the instrument between A and B points.
Take readings “a1” and “b1”. (Pic.10)
2) Set up the instrument at 2 m off the point A. Take readings “a2” and “b2”
(Pic.11).
Let the telescope be pointing at front staff.
Pic.10
Compute
b2'=a23-(a1-b1)
if b2'=b2, there is no need in adjustment.
If the difference between b2' and b2 is significant, make the adjustment
in following order:

3) Provide an access to the adjusting screws.

Clamping screws
Pic.12
4) If the difference between b2' and b2 is positive (negative), horizontal line should be raised (lowed). To raise/low
horizontal line you should screw/unscrew adjusting screw. Determine new difference value b2'-b2 and if necessary,
repeat the adjustment.
Note: to remove “skew” of reticule loosen clamp screw, turn the ocular.
6. THE ACTION OF THE INSTRUMENT
6.1. DETERMINATION OF ELEVATION
1) Set up the instrument between the A and B points (Pic.13)
Note: to check the distance use stadia hair of reticule.
For more accurate measurements set up the instrument close to the center of distance between staffs. It helps you to
avoid errors which result from noncoincidence of axis of sight.
2) Set up the staff at A point. Take readings ‘‘a’’ (back staff) along the staff at A point.
11
MEASUREMENT FOUNDATION
2) Set up the staff at A point. Take readings ‘‘a’’ (back staff) along the
staff at A point.
3) Point at the staff which is set up at B point and take readings “b”
(front staff).
4) The difference “a-b” is the elevation “h” point to A point (Pic.13)
Example:
H=a-b
=1.735 m
-1.224 m
=0.511 m
Thus B point is higher than A point on 0.511.
(Elevation value will be negative, if B point is lower than A point).
<If the distance between A and B points is too big or height
difference is signicant>
1) Divide the distance into several sections and determine the elevation
for every section. Pic.13
