Switching On/Off

To switch on the measuring tool, briefly press the measuring button (2). The measuring
tool and laser are switched on.
Never leave the measuring tool unattended when switched on, and ensure the
u
measuring tool is switched off after use. Others may be dazzled by the laser beam.
To switch off the measuring tool, press and hold the measuring button (2).
Measuring Process (see figure A)
Once switched on, the measuring tool is in the length measurement function.
The rear edge of the measuring tool is always the reference level for the measurement.
Apply the measuring tool to the point at which you want to start the measurement (e.g.
wall).
To initiate the measurement, briefly press the measuring button (2). Then the laser
beam is switched off. To switch the laser beam on again, briefly press the measuring but-
ton (2). To initiate a further measurement, briefly press the measuring button (2) again.
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 0.5 seconds and no later than 4
seconds. The duration of the measurement depends on the distance, the lighting condi-
tions and the reflective properties of the target surface. Upon completion of the meas-
urement, the laser beam is automatically switched off.
Auto-Sum (see figure B)
The auto-sum automatically shows the sum of all individual measurements (e.g. useful
for the material calculation).
The auto-sum value is erased as soon as the device is switched off or if it automatically
switches off when no button is pressed after 5 minutes.
The auto-sum is not saved. A subsequent correction of the auto-sum is not possible.
Aim the laser beam at the target surface.
To initiate the measurement, briefly press the measuring button (2).
The current measured value (c) is shown on the bottom line of the
display. The laser beam is switched off.
