7 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 fi ve times.
8 OPERA TING 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.
9 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 fi ne adjustments.
10 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.
