A middle sign plus a lit green light indicates the laser signal is on grade. Note: When the laser signal moves towards the center position, the displayed up or down arrows will decrease in size, until the center single line appears. C.
1622i_Manuals 12/14/16 12:52 PM Page 18 Sound function on: • If the laser signal is on the top (left) side, then the detector will give a fast tone. • If the laser signal is on the bottom (right) side, then the detector will give a double tone. • If the laser signal is on the middle, then the detector will have a solid tone. 4.
1622i_Manuals 12/14/16 12:52 PM Page 19 8. Self-Check & Fine Calibration IMPORTANT: It is the responsibility of the user to verify the calibration of the instrument before each use. Horizontal line accuracy (horizontal) 1. Place unit on a tripod approximately 5m from a wall. Secure the instrument on the tripod. 2. Face the front of the instrument to the wall, unlock the instrument, and power on the horizontal and vertical laser lines. Make a mark on the wall where the cross-line is displayed.
1622i_Manuals 12/14/16 12:52 PM Page 20 3. Power on horizontal and vertical laser lines, and make a mark where the cross laser meets target ‘A’. Mark this as ‘A1’. 4. Turn the instrument by 180°, so that the cross line meets target ‘B’. Mark this as ‘B1’. 5. Move the tripod within .6m of target ‘A’. Make a mark where the cross meets target ‘A’, and label as ‘A2’. 6. Rotate the instrument by 180° and make a mark where the cross meets target ‘B’, and label as ‘B2’. 7. Calculate (A1-A2)-(B1-B2) = E.
1622i_Manuals 12/14/16 12:52 PM Page 21 Dot Accuracy 1. With the laser on its base and set on a flat platform, turn the laser on. 2. Mark the down beam location and use this as your reference point. 3. Locate the up beam and mark its point as ‘A’. 4. Rotate the laser (not moving the base) 180° by swiveling the laser on its base and mark the up beam location as ‘B’. 5. Rotate the laser 90° and mark the up beam as ‘C’. 6. Rotate the laser 180° and mark the up beam as ‘D’.
1622i_Manuals 12/14/16 12:52 PM Page 22 7. Perform another self check calibration as described previously to make sure the laser is calibrated. 8. If the laser is still beyond its accuracy specification, recalibrate the laser again. 9. If laser is still out of calibration, contact Johnson Level & Tool for service. 10. Return the plastic screws, being careful not to over-tighten. Self-checking the 3 Horizontal Beams 1. As shown in Fig.
