Q: How to use the laser to create or check right angles?

Your BOSCH GRL 650 CHVG Professional laser allows you to create and check right angles thanks to its different emission modes and its accuracy of ±1.5 mm at 30 meters. Method 1: Use Point Mode and Perpendicular Lines Switch the device to Point Mode to mark a reference point on the ground Place the laser where you want to form the right angle Then use Line Mode (mobile beam within a limited angular range) to project a first horizontal line Rotate the laser 90° to draw the perpendicular line Method 2: Use the Tilt Function The GRL 650 CHVG has a tilt function that allows you to tilt the axes up to ±8.5° . This function remembers the last 4 tilt combinations, useful if you need to repeat the same right angle multiple times without recalibration. Key Points The automatic leveling system (range ±5°) compensates for small inclinations during positioning The Rotation Mode (150/300/600 rpm depending on setting) creates a continuous horizontal reference line By combining a horizontal beam and a vertical beam using Point Mode , you achieve a perfect right angle for your alignments Refer to the details of the modes in the PDF manual above to access the mode selection menus.

Question

Accepted Answer

Your BOSCH GRL 650 CHVG Professional laser allows you to create and check right angles thanks to its different emission modes and its accuracy of ±1.5 mm at 30 meters.

Method 1: Use Point Mode and Perpendicular Lines

Switch the device to Point Mode to mark a reference point on the ground
Place the laser where you want to form the right angle
Then use Line Mode (mobile beam within a limited angular range) to project a first horizontal line
Rotate the laser 90° to draw the perpendicular line

Method 2: Use the Tilt Function

The GRL 650 CHVG has a tilt function that allows you to tilt the axes up to ±8.5°. This function remembers the last 4 tilt combinations, useful if you need to repeat the same right angle multiple times without recalibration.

Key Points

The automatic leveling system (range ±5°) compensates for small inclinations during positioning
The Rotation Mode (150/300/600 rpm depending on setting) creates a continuous horizontal reference line
By combining a horizontal beam and a vertical beam using Point Mode, you achieve a perfect right angle for your alignments
