Measuring Procedure

Once switched on, the measuring tool is in the length measurement function. For a
different measuring function, press the button 7 [Func]. Select the desired measur-
ing function with the buttons 3 [+] or the button 8 [–] (see "Measuring Functions",
page 35). Activate the measuring function with button 7 [Func] or with the measur-
ing button 2 [ ].
After switching on, the rear edge of the measuring tool is preset as the reference level
for the measurement. To change the reference level, see "Selecting the Reference
Level", page 34.
Place the measuring tool against the desired starting point of the measurement (e.g.
a wall).
Note: If the measuring tool has been switched on using the On/Off button 5 [
briefly press the measuring button 2 [
To initiate the measurement, briefly press the measuring button 2 [
ser beam is switched off. For a further measurement, repeat this process.
Do not point the laser beam at persons or animals and do not look into the
laser beam yourself, not even from a large distance.
Note: The measured value typically appears within 0.5 s and no later than approx.
4 s. 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
measurement the laser beam is automatically switched off.
Selecting the Reference Level (see figure A)
For the measurement, you can select between three different reference planes:
– the rear measuring-tool edge (e.g. when measuring onward from a wall),
– the front measuring-tool edge (e.g. when measuring onward from a table edge),
– the centre of thread 13 (e.g. for tripod measurements).
