If rechargeable are used, first recharge the batteries. See battery section.
Charging the batteries The charger requires approx. 10 hours to charge empty rechargeable batteries. For this charging, connect the plug of the charger to the recharge jack of the unit. New or long-time out-of-use rechargeable batteries reach their best performance after being charged and recharged five times. The batteries should only be charged when the laser is between 50° F and 104° F (10° C to 40° C) Charging at a higher temperature may damage the batteries.
OPERATING EXAMPLES Determining the Height of Instrument (HI) The height of instrument (HI) is the elevation of the laser’s beam. The HI is determined by adding the grade-rod reading to a benchmark or known elevation. Set up the laser and place the grade rod on a job-site benchmark (BM) or known elevation. Slide the receiver up/down the grade rod until it shows an on-grade reading. Add the grade-rod reading to the benchmark to determine the height of instrument. Example: Benchmark = 30.55 m (100.
In order to avoid offset errors, the receiver should be used close to the elevation where the laser has been set up. If a remote control is available, the up and down arrow buttons can be used for fine adjustments. LEVELING ACCURACY Influences on the leveling accuracy The overall accuracy of the unit can be influenced by many factors: • factory accuracy; • temperature of the unit; • ambient influences like rain, wind and temperature.
If the unit is within its working accuracy limits (± 20”) the maximum difference from true level at 20 m (65 ft.) + 20 m (65 ft.) = 40 m (130 ft.) is 4 mm (3/16 inch). Repeat the above steps for “minus X” and for “plus-” and “minus Y”, so that a measurement for all four axes of the unit have been performed. The accuracy of the detector has to be regarded. PROTECTING THE UNIT Do not expose the unit to extreme temperatures or temperature changes (do not leave inside the car).
