Display Illumination; Measuring Functions - Bosch GLM 500 Professional Originalbetriebsanleitung

Apply the measuring tool to the point at which you want to start the measurement (e.g.
wall).
Note: If the measuring tool has been switched on using the on/off button (5) [ ], briefly
press the measuring button (2) [ ] to switch the laser on.
To initiate the measurement, briefly press the measuring button (2) [ ]. Then the laser
beam is switched off. For a further measurement, repeat this process.
Do not direct the laser beam at persons or animals and do not stare into the laser
u
beam yourself (even from a distance).
Note: The measured value typically appears within half a second, and no later than ap-
proximately four seconds. The duration of the measurement depends on the distance,
the lighting conditions and the reflective properties of the target surface. Upon comple-
tion of the measurement, the laser beam is automatically switched off.
Selecting the reference level (see figure A)
You can choose between three different reference levels for the measurement:
– The rear edge of the measuring tool (e.g. when placing against walls)
– The front edge of the measuring tool (e.g. when measuring from a table edge)
– The centre of the thread (13) (e.g. for tripod measurements)
To select the reference level, press the button (4). Use the [+] button (3) or the [–] but-
ton (8) or the button (4) to select the required reference level. The rear edge of the
measuring tool is preset as the reference level every time the measuring tool is switched
on.
