SatLab Titan TAL32 User manual
FOREWORD
Thank you for purchasing the Satlab Automatic Level TAL32. For the best performance of the
instrument, please read this user manual carefully and keep them for future reference.
INTRODUCTION
Suitable for construction projects, mines, road works etc., this instrument is equipped with
an air compensator. A high precision leveling line will settle automatically after the circular
bubble is adjusted properly.
The telescope system is equipped with multilayer coating lens. Its high transmission rate is
also able to bring out clear and stable image for your work.
On top of that, its IP66 standard protects this instrument from dust and water, which expands
its range of working environment.

WARNING
• Never observe the sun through the telescope system.
• Please be careful when working around high voltage facilities.
• Do not handle staff during thunderstorms.
• Please pay attention to the spiked feet of the tripod during transportation and operation.
• The survey should be operated in a safe area.
• Please observe local safety and traffic rules.

2. Instrument Operation
2.1 Instrument Setting
• Extend the tripod legs until the top
holder is at eye level.
• Tighten screws and stick tripod legs
firmly into the ground.
• Set the instrument and tighten the
centering screw. (fig. 1)
• Move the bubble to the centre of the
circle by adjusting the foot screws (fig. 2).
Adjust A and B screws to move the bubble
left and right, then adjust C screw to move
the bubble into the centre circle. A B

2.2 Sight and Focusing
• Rotate the eyepiece to make the reticle clear (fig.
3).
• Target the staff through the peep sight. Then
rotate the focusing knob to ensure that the staff
image is clear. Coincide the vertical hair with the
middle of the staff (fig. 4).
• Move your eye sight right, left, up and down. If
staff image and reticle hair remains still, you can
proceed with your work.

2.3 Measurement
2.3.1 Height Measurement
• Use the ruler side of the staff and keep it vertical.
• Adjust the eyepiece and focusing knob to make the reticle and staff images clear
• Read data as shown in fig. 5, H = 1.403m
2.3.2 Height Difference
• Set up the instrument at a point approximately halfway between point A and point B
• Position the staff vertically at point A, take the reading as ‘a’
Example: a = 1.735m
8
Fig. 5
• Then read the staff at point B and obtain the reading as “b”
Example: b = 1.224m
• The difference a-b is the AB height difference “h”
Example: h = a - b = 1.735m - 1.224m = 0.511m
2.3.3 Stadia Measurement
Read the staff and count the difference of L between two stadia lines (fig. 7)
Upline: 1.480m
Downline: 1.328m

Fig. 8
Difference L = 1.480m -1.328m = 0.152m
Distance D = 100 * L = 15.2m
2.3.4 Angle Measurement
• Direct instrument to staff A and turn
Horizontal Circle to “0” (fig. 8)
• Point instrument to staff B
• Read off Hz-angle from Horizontal
Graduation Circle (fig.14): Hz = 54°

3. Checking and Adjustment
Please check the instrument before starting your work. The instrument
must be checked and adjusted by a trained person regularly.
3.1 Circular Bubble
• Center the bubble of the circular level
precisely by using the leveling foot
screws.
• Turn the telescope around 180° (fig. 9).
• The bubble needs adjusting if it is not
centered.
• Adjust the leveling foot screws to move
the bubble to the middle place of the
error (fig. 10).
12
3.2 Line of Sight
• Set the instrument at a point
halfway between point A and B,
spaced about 30-40m apart.
Take the readings of staff A and
B as “a1” and “b1” (fig. 12)
Calculate the real height
difference: ∆H = a1-b1
• Adjust the rest half of error by using
the allen key (fig. 11).
• Repeat the above steps until the
bubble remains centered when the
telescope is pointed at any direction.
Fig. 11
Fig. 12
13
• Set up the instrument about 1m away from point A. Then read staff A and staff B as “a2”
and “b2” (fig. 13).
• Then you can get the logical value b2’ = a2 - ΔH , b2’ is the height b2 should be
• When the difference between b2 and b2’ is more than 3mm, the line of sight
must be adjusted.
