Functions
In CenterFind mode, the rotary laser automatically attempts to align the laser beam to the centre line of the laser receiver by moving the rotation head up and down.
If the rotary laser is in the horizontal position, the laser beam can be aligned in relation to the X-axis of the rotary laser, to the Y-axis or to both axes at the same time see Inclination determination with CenterFind mode (see figure D). If the rotary laser is in the vertical position, only alignment to the Y-axis is possible.
Start CenterFind mode:
Position the rotary laser and laser receiver so that the laser receiver is situated in the direction of the X-axis or the Y-axis of the rotary laser. Align the laser receiver so that the required axis is at a right angle to the reception area (1).
If the laser beam is aligned to both axes, then place a laser receiver connected to the rotary laser in the direction of the X- and Y-axis respectively. Each laser receiver must be situated within the pivoting range of ±8.5 % of the rotary laser.
Switch on the rotary laser in rotational operation.
LR 65 G: In the settings menu, the centre function must be put in CenterFind (CF) mode. When aligning to two axes of the rotary laser, this applies to both laser receivers.
To start the CenterFind mode for the X‑axis, either press and hold the CenterFind (17) mode button, or press and hold the CenterFind (17) mode button, together with the X‑axis button (16).
To start the CenterFind mode for the Y-axis, press and hold the CenterFind (17) mode button, together with the Y‑axis button (15).
Should the laser beam be aligned to both axes at the same time, CenterFind mode must be started separately on each laser receiver.
Following the start of CenterFind mode, the rotary head on the rotary laser moves up and down. During the search process, CFX (X‑axis) or CFY (Y‑axis) appears in the text display (e).
If the laser beam hits the reception area (1) at the height of the centre line of the laser receiver, the centre line indicator (h) will appear and XOK (X axis) and YOK (Y axis) will appear in the text display (e). The value of the incline that is found is displayed on the rotary laser. CenterFind mode will be ended automatically.
Cancelling CenterFind mode:
To cancel the CenterFind mode, press and hold the CenterFind mode button (17).
Troubleshooting:
If the laser beam was unable to find the centre line of the laser receiver within the pivoting range, ERR appears in the text display (e) and all LED direction indicators light up. Press any button on the rotary laser and one on the laser receiver to close the error messages. Reposition the rotary laser and laser receiver so that the laser receiver is situated within the pivoting range of ±8.5 % of the rotary laser. Ensure that the laser receiver is aligned to the X-axis or Y-axis so that the laser beam can pass through the reception area (1) horizontally. Then restart the CenterFind mode.
LR 65 G: If both axes of the rotary laser should be aligned to a laser receiver, the same centre function must be set on both laser receivers. A combination of CenterFind mode and CenterLock mode is not possible.
If CenterLock mode is already set on one axis and CenterFind mode is started on the other axis, ERR and CL will appear alternately in the text display (e). Select CenterFind mode on both laser receivers and re-start the function.
Using CenterFind mode, the inclination of a surface can be measured up to max. 8.5 %. To do this, set up the rotary laser at one end of the inclined surface in a horizontal position on a tripod. The X- or Y-axis of the rotary laser must be aligned with the inclination to be determined. Switch on the rotary laser and allow it to level in.
Secure the laser receiver to a measuring rod (25) with the holder. Place the measuring rod near to the measuring tool (at the same end of the inclined surface). Align the height of the laser receiver on the measuring rod so that the laser beam of the rotary laser is indicated as "centred" ➊.
Then place the measuring rod with the laser receiver at the other end of the inclined surface at ➋. Ensure that the position of the laser receiver on the measuring rod remains unchanged.
Start CenterFind mode for the axis to which the inclined surface is aligned. At the end of CenterFind mode, the inclination of the surface is shown on the rotary laser.
In CenterLock mode, the rotary laser automatically attempts to align the laser beam to the centre line of the laser receiver by moving the rotation head up and down. In contrast to the CenterFind mode, the position of the laser receiver is continually checked and the inclination of the rotary laser automatically adjusted. No slope values appear on the display of the rotary laser.
Alignment is possible for the X‑axis and Y‑axis both when the rotary laser is in a horizontal position and when it is in a vertical position.
Start CenterLock mode:
Position the rotary laser and laser receiver so that the laser receiver is situated in the direction of the X-axis or the Y-axis of the rotary laser. Align the laser receiver so that the required axis is at a right angle to the reception area (1).
If the laser beam is aligned to both axes, then place a laser receiver connected to the rotary laser in the direction of the X- and Y-axis respectively. Each laser receiver must be situated within the pivoting range of ±8.5 % of the rotary laser.
Switch on the rotary laser in rotational operation.
In the settings menu of the laser receiver, the centre function must be put in CenterLock (CL) mode. When aligning to two axes of the rotary laser, this applies to both laser receivers.
To start the CenterLock mode for the X‑axis, either press and hold the CenterFind (17) mode button, or press and hold the CenterFind (17) mode button, together with the X‑axis button (16).
To start the CenterLock mode for the Y-axis, press and hold the CenterFind (17) mode button, together with the Y‑axis button (15).
Should the laser beam be aligned to both axes at the same time, CenterLock mode must be started separately on each laser receiver.
Following the start of CenterLock mode, the rotary head on the rotary laser moves up and down. During the search process, CLX (X‑axis) or CLY (Y‑axis) appears in the text display (e).
If the laser beam hits the reception area (1) at the height of the centre line of the laser receiver, the centre line indicator (h) and the text display (e) LOC will appear. The CenterLock symbol is displayed on the rotary laser on the start screen for the corresponding axis.
In the event of changes to the position of the laser receiver or rotary laser, the inclination is automatically adjusted on the rotary laser.
- Take great care when working with the CenterLock mode that rotary lasers and laser receivers are not moved unintentionally. Incorrect measurements can arise from the automatic adjustment of the inclination with every change of position.
Cancelling CenterLock mode:
To cancel or end the CenterLock mode, press and hold the CenterFind mode button (17). If the laser beam was already successfully aligned with the centre line of the laser receiver at this point, the set inclination remains on the rotary laser even when CenterLock mode is cancelled.
Troubleshooting:
If the laser beam was unable to find the centre line of the laser receiver within 2 min (no matter whether at the start of the mode or after changes to position), ERR appears in the text display (e) and all LED direction indicators light up.
Press any button on the rotary laser and one on the laser receiver to close the error messages. Reposition the rotary laser and laser receiver so that the laser receiver is situated within the pivoting range of ±8.5 % of the rotary laser. Ensure that the laser receiver is aligned to the X-axis or Y-axis so that the laser beam can pass through the reception area (1) horizontally. Then restart the CenterLock mode.
If both axes of the rotary laser should be aligned to a laser receiver, the same centre function must be set on both laser receivers. A combination of CenterLock mode and CenterFind mode is not possible.
If CenterFind mode is already set on one axis and CenterLock mode is started on the other axis, ERR and CF will appear alternately in the text display (e). Select CenterLock mode on both laser receivers and re-start the function.
