AutoCross-Laser ACL 4C / ACL 4C RX - Spot-on.net

<strong>AutoCross</strong>-<strong>Laser</strong> <strong>ACL</strong> <strong>4C</strong> / <strong>ACL</strong> <strong>4C</strong> <strong>RX</strong>Preparing the calibration check:It is possible for you to check the calibration of the laser. To do this, positionthe device midway between 2 walls, which must be at least 5 metres apart.Switch the device on (<strong>Laser</strong> cross ON). The best calibration results are achievedif the device is mounted on a tripod. 1. Mark point A1 on the wall.2. Turn the device1.through 180° andA1mark point A2.You now have a2.horizontal referenceA2 between points A1and A2.Performing the calibration check:3. Position the device as near as possible to the wall at the height of3.A1A2A2point A1.4. Turn the devicethrough 180° andmark point A3. The4.A3difference betweenA2 points A2 and A3 isA3 the tolerance.Note: If points A2 and A3 are imore than 2 mm / 10 m, the device is inneed of calibration. Contact your authorised dealer or else the UMAREX-LASERLINER Service Department.Checking the vertical line: Position the device about 5 m from a wall. Fix aplumb bob with a line of 2.5 m length on the wall, making sure that the bobcan swing freely. Switch on the device and align the vertical laser to the plumbline. The precision is within the specified tolerance if the deviation between thelaser line and the plumb line is not greater than ± 1.5 mm.Checking the horizontal line:2,5 mPosition the device about 5 m from a wall andswitch on the cross laser. Mark point B on the wall. BCTurn the laser cross approx. 2.5 m to the right andmark point C. Check whether the horizontal linefrom point C is level with point B to within ± 2 mm. Repeat the process byturning the laser to the left.14< 2 mm / 10 m = OKenglish< 2 mm = OK
