USER MANUAL AL 26 Plus Laserliner

General safety instructions – The device must only be used in accordance with its intendedpurpose and within the scope of the specications. – The measuring tools and accessories are not toys. Keep out of reach of children. – The structure of the device must not be modied in any way. – Do not expose the device to mechanical stress, extreme temperatures, moisture or signicant 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.

Completely read through the operating instructions, the „Warranty and Additional Information“ booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and passed on together with the device.

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 waterproof10

AL 26 AL 32 The AL32 has segmentation within the crosshairs for accurate targeting.

1. Bring crosshairs into focus (5)

Initial alignment of the telescope towards the graduated staff is done by hand, using the iron sights.

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). 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.

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.

Distance determination

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 = 100 x e), the result is the distance E = 8 m. To achieve reliable results make sure the levelling staff is precisely aligned vertically.

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 (see calibration).

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.

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. ENAL 26 / 32 Plus

Adjustment will be required if the height differences are not the same. Contact your authorised dealer or else the UMAREX-LASERLINER Service Department.

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

Now direct the levelling instrument at levelling staff B. Read the value b

and calculate the height difference, which is (a

The adjustment of the level is correct when you get the reading (a

). 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. Crosshairs

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

from the level- ling staff A and the value b

from the levelling staff B. Calculate the height difference (a
