Frequently Asked Questions - AL 32 Plus Laserliner

How to focus the reticle of the AL 32 Plus?

Turn the eyepiece (5) until the reticle (crosshairs) appears sharp. Then focus on the staff using the focusing knob (4) so that the staff image is also sharp.

How to measure a height difference with this level?

Place the instrument halfway between two staffs A and B. Read the value on staff A (e.g., 140 cm), then on staff B (e.g., 90 cm). The difference A - B = +50 cm indicates that B is 50 cm higher than A.

How to determine a distance using the stadia reticle?

Read the value on the upper line (O) and lower line (U) of the reticle. The difference e = O - U, multiplied by 100, gives the distance E = 100 x e. For example, if O = 1.44 m and U = 1.36 m, then e = 0.08 m and E = 8 m.

How to measure a horizontal angle?

Place the instrument on a tripod, center it over the starting point. Aim at the first target point, set the horizontal circle to 0° using the knurled ring. Then aim at the second point and read the angle under the index line.

How to calibrate the circular vial?

Center the bubble using the leveling screws. Rotate the telescope 180°. If the bubble leaves the circle, adjust half of the deviation with the vial calibration screws. Repeat until the bubble remains centered after rotation.

How to check the accuracy of the compensator and reticle?

Set up the instrument halfway between two staffs 30 m apart. Read values a1 and b1 and calculate the difference. Then place the instrument 2 m from one staff, read a2 then b2. If (a1-b1) = (a2-b2), the instrument is correct. Otherwise, contact customer service.

What is the maximum distance measuring range?

The minimum staff range is 0.5 m. The maximum range depends on visibility and staff size. Theoretically, with a 4 m staff, the maximum distance is about 400 m (since the stadia reticle covers up to 4 m).

How to maintain the AL 32 Plus?

Clean the lenses with a soft, dry cloth or compressed air. Do not use solvents. Store the instrument in its case, in a dry place. Do not subject it to shocks or extreme temperatures.

What are the recommended working conditions?

Temperature from -20°C to 50°C, relative humidity max. 80% without condensation, altitude max. 4000 m. Allow the instrument to adapt to ambient temperature for 15 minutes before measurements.

Is the AL 32 Plus waterproof?

Yes, it has IP64 protection, meaning it is protected against dust (6) and water splashes (4). However, it should not be submerged.

Sturdy and reliable levelling instruments for the building and construction industry, with a high-performance lens producing a bright image

• Automatic horizontal levelling of the target line with precision, air-damped compensator.
• Distance determined with the aid of the marks on the crosshairs with easy conversion of the read value from centimetres to metres (multiplier 100).
• Practical mirror for easy alignment with circular bubble level.
  – Horizontal circle with endless vernier adjustment for precise targeting.
  – Iron rear- and foresight for rapid pick-up of aim.
• Convenient controls for easy, time-saving operation.
  – Dust- and waterproof

General safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• The measuring tools and accessories are not toys.
  Keep out of reach of children.
• The structure of the device must not be modified in any way.
• Do not expose the device to mechanical stress, extreme temperatures, moisture or significant vibration.
• The device must no longer be used if one or more of its functions fail or the battery charge is weak.
• Do not aim at bright light sources (laser, lamps, sun) as this can damage your eyes.
• Do not touch the optical lenses with your hands.
• Use air to blow dust off the optical lenses.
• To transport the levelling instruments secure them with the compensator lock in the original carrying case.
• Do not set up the tripod on unsecured roads: Risk of accident.

To rule out inaccuracies, the device should be placed at the measuring location 15 minutes before taking a measurement to allow it to assume ambient temperature.

1 Alignment

1. Bring crosshairs into focus (5)
2. Initial alignment of the telescope towards the graduated staff is done by hand, using the iron sights.
3. Focus the image of the staff, by operating the focusing knob, turn crosshairs onto the staff centre.
4. Make sure focusing is free of parallax. The focusing is alright when crosshairs and graduation of the staff don't change their positions even when looked at from different angles (keep changing position of the eye in front of the eyepiece).

AL 26 AL 32

The AL 32 has segmentation within the crosshairs for accurate targeting.

Remaining inclinations of the crosshairs which are left after the levelling bubble has been centred will be eliminated by the compensator. The compensator, however, will not eliminate any inclinations caused by faulty calibration of the levelling bubble or the crosshairs. Therefore, the positions of both gadgets should be checked before measuring (seecalibration).

2 Determination of a height difference

1. Place instrument halfway between the positions of staves A and B. Aim instrument at staff A and read the value of the graduation of the staff at your crosshairs (e.g. A = 140 cm). Turn instrument towards rod B and get the reading from the graduation (e.g. B = 90 cm).
2. The difference (A-B) results in a height difference H=+50 cm

between B and A. The point B is 50 cm higher than point A.

The difference H turns negative when point B is lower than point A.

A ½L ½L B

3 Distance determination

1. Read values of the upper graduation mark (0 = 1.44 m) and the lower graduation mark (e.g. U = 1.36 m).
2. Multiply the difference by the factor 100 (E=100xe), the result is the distance E=8m.

O=1.44 m 14 e U=1.36 m

To achieve reliable results make sure the levelling staff is precisely aligned vertically.

4 Angle measurement

1. Attach the plumb line to the hook and set up the tripod with the tripod head such that the plumb is roughly over the ground point. Tread legs of tripod firmly into the ground.
2. Attach instrument to tripod and fix it. Now centre the plumb bob exactly over the point by adjusting the lenghts of the tripod legs or by changing the position of the instrument on the tripod.
3. With the aid of your iron sights, aim telescope at the first aim, align by using the lateral fine adjustment. Now turn knurled ring until the index and the zero position of the horizontal dial are congruent (turn dial onto zero).
4. Aim telescope at the second aim and read the angle function under the index marking.

5 Calibration

Levelling bubble

1. Control: Set horizontal dial onto 0^ . Place bubble right into the centre of the circle on the levelling bubble by turning the levelling screws (6). Turn telescope through 180^/200 gon. The circular bubble level is correctly aligned when the bubble is still in the centre.

2. Adjustment: In case the bubble is now out of the centre marking, set half of the deviation „a“ which is (fi a) by operating the three calibration screws on the levelling bubble. After that, adjust levelling bubble by using the levelling screws, then check calibration by turning the whole instrument through 180°/200 gon.

3. Repeat control and calibration until the bubble of the levelling bubble remains in the inner circle after each turn of the instrument.

The measuring device should be calibrated and tested on a regular basis to ensure it is accurate and working properly. We recommend the measuring device is calibrated every year. If necessary, contact your distributor or the UMAREX-LASERLINER service department.

Crosshairs

1. Control:

Set up and align the instrument in the middle between two fixed level-ling staff positions A and B approx. 30 m apart.

Read off the value a_1 from the levelling staff A and the value b_1 from the levelling staff B. Calculate the height difference (a_1-b_1) .

Now place instrument in a distance of approx. 2 m away from staff A and read the value a_2 .

Now direct the levelling instrument at levelling staff B. Read the value b_2 and calculate the height difference, which is (a_2-b_2) .

L = 30 m a₁ ½L ½L b₁ A B

A a₂ 2 m b₂sol b₂ B

The adjustment of the level is correct when you get the reading (a_1-b_1)=(a_2-b_2) . This means that the values of the height differences achieved with the first and the second measurement are equal, and the instrument operates error-free.

Adjustment will be required if the height differences are not the same.

Contact your authorised dealer or else the UMAREX-LASERLINER Service Department.
