4. CALIBRATION Calibration checks should be done regularly to ensure good results Mount the DL on a tripod Set X and Y grades to 0 Using the sight grove aim the laser in positive X direction at a receiver at a distance of 50m set the reciever to its minimum deadband Adjust the height to get a stable centre reading from the receiver Turn the laser around 180 degrees aim at the receiver and check the height difference Do the same check in the Y direction If you error in any of the axes is larger than 5mm your laser is out of calibration and should be sent to your AMA Laser Systems dealer for calibration 4 BATTERY POWER The DL is powered by an in built battery pack The battery life during operation is about 60 hours under normal conditions with a fresh battery pack With a worn battery pack and in cold temperatures the laser can still operate some 20 hours Using a lower rotation speed will prolong the lasers operation time per charge The battery indicator 15 on the display gives a rough indication of the remaining battery life The display will show a blinking battery indicator when the battery is low and close to power down If the DL shuts down due to low battery the display will show bA Lo In this case shut the laser off and charge Charge the battery for 7 hours for full charge The first 4 hours will charge fast The laser can be operated when charging In emergency situations as little as 15 minutes of charging will give
