4. arging will drain the batteries causing poor capacity You will need to charge and discharge a couple of times to get the battery up to full capacity after a longer period on the shelf This will however not cause noticeable permanent damage For best performance make a habit of maintenance charging once per month 5 PLANNING FOR YOUR DLP USAGE There are three main modes of operation for the DLP Self levelling plumb beam Self levelling inclined beam Manually adjusted beam Regardless of the mode of operation you select keep in mind that any instrument can give false readings because of malfunction or mishandling Make sure to always doublecheck the accuracy with frequent geodetic measurements or by process of elimination i e using many lasers This is particularly important in slipforming projects where there can be no doubt on the accuracy When deciding on the laser setup strategy keep the following in mind On high structures keep the laser beam well away from curing concrete walls preferably 1 2 meters If too lose heat convection will cause errors because of mirage style deviation of the laser beam All instruments are sensitive to changing temperature In hot sun exposed cold or changing conditions consider covering the laser setup with a wooden housing Make sure the laser is mounted on a rigid structure that will not shift due to knocking mud setting or heavy vibration Take care to protect the la

8. operation is sometimes used for inclined pylons etc The way of setting up and operating follows the above section on self levelling plumb beam with one addition The laser needs to be set up accurately with regards to the X direction To achieve this a wide variety of sights and scopes can be used Pay attention to the rotation alignment as an error of 5 arc minutes at an inclination of 10 gives an error of 7mm on 50meter distance There is a special function under the user configuration mode that enables you to field calibrate the X axis to the scope Read more about the SCOPE function under 3 Operation Use the X axis for inclination between 5 and 20 use the second tilted 5 8 thread for inclinations above 12 Manually adjusted beam This mode of operation is used when the structure is built floating or when the structure can shift during construction The beam is fixed with reference to its mounted housing with no reference to the true verticality no self levelling action In this mode mount the laser fixed to the structure so that it follows any movements the structure is doing After mounting the laser let it stabilise in the Auro mode to achieve a vertical beam then switch to MANUAL mode Use the arrow buttons to move the beam to the desired position 6 TECHNICAL SPECIFICATION Laser source sseR e Visible diode 635nm Class 3R Range dose tdeo de e Re Seeds 200m Accuracy at 0 inclination
