PREPARING FOR WORKING
1. Mount the level on a tripod.
2. By adjusting the tripod legs,
coarsely level the level.
3. Accurately level the level using
levelling screws, vial bubble should
be in the centre of vial.
AIMING
1. Turn the telescope onto bright background. Turning the eyepiece sharpen the crosshair
vision.
2. Using the collimator turn the telescope onto the staff.
3. Looking trough the telescope, turn the focusing knob to sharpen the staff vision.
4. Using the tangent screw set the vertical crosshair line on the staff.
MEASUREMENTS
1. Height measurement:
- read the value on the staff using middle line
Height reading on the picture is 3,456m
3
2. Distance measurement:
- read the value on the staff using upper and lower line. Difference between those lines
multiplied by 100 is equal to distance between level and the staff. On the picture reading of
upper line is 3,601m. Reading of lower line 3,309m.
Distance between level and staff is 100*(3,601-3,309)=29,2m
3. Angle measurement:
- aim at point A and write down the reading of horizontal wheel α
- aim at point B and write down the reading of horizontal wheel β
- calculate the angle AOB = γ= α–β
CHECKING AND CALIBRATING
1. Circular vial:
Checking: using the levelling screws move the bubble to the centre of the vial. Turn the
instrument 180°. Vial bubble should be still in centre. If it's not calibration is necessary.
Calibration: Using levelling screws remove the half of vial bubble inclination, next using the
calibration wrench move the bubble to the centre of the vial. Check the vial again.
2. Crosshair:
Checking: Place staves in distance from 30m to 50m between of them. Place the level in half of
distance between the staves. Using the levelling screws, level the vial.
Perform the reading of staff A in example
1,924m. Perform the reading of staff B in
example 1,712m
Calculate the height difference H=A-B in
example 0,212m
Set the level near staff A (about 1 m from
staff). Aim at staff A and make the reading
in example 1,696m. From reading of A staff
subtract calculated height difference, the
result with accuracy 3mm should be equal
reading on staff B in example 1,484m. If the
difference is greater the calibration is
necessary.

Calibration: Remove the eyepiece cover. Gently turn the calibration screw to crosshair set the
calculated earlier value on a staff in example 1,484m. Replace the eyepiece cover.
General notes
The following suggestions will help in the long comfortable work of level:
1. After finishing the measurements, clean the level before
putting it in box.
2. For cleaning lens use soft brush or special cloths. Never touch the lens by fingers
3. If the instrument was damaged or it doesn't work properly it should be fixed by authorized
service.
4. The level should be kept in clean, dry and breezy place.
5. While transporting the level you should avoid impacts and vibrations.
