Indirect Distance Measurement - Bosch GLM 80 Operating And Safety Instructions Manual

For continuous measurements,
press function mode button 4 until
the indicator

display. To start the continuous
measurement,
measuring button 2.
The minimum measurement is
used to determine the shortest
distance from a fixed reference
point. It is used, as an example, for
determining
horizontal partitions.
The maximum measurement is
used to determine the greatest
distance from a fixed reference
point. It is used, as an example, for
determining diagonals.
("min") measuring value are
displayed in the measured value
lines a.
It is always overwritten,when the
current length measurement value
is less than the present minimal or
larger than the present maximal
value.
The previous
maximal values are deleted by
pressing the button for clearing the
internal memory 8.
Pressing the measuring button 2
ends the

Indirect Distance Measurement

or
The
measurement is used to measure
distances
measured directly because an
obstacle would obstruct the laser
beam or no target surface is
available as a reflector. This
measuring procedure can only be
used in vertical direction. Any
deviation in horizontal direction
leads to measuring errors.
The laser beam remains switched
on between
measurements.
For indirect length measurements,
three
available. Each measuring mode
can be used for determining
different distances.
a) Indirect height measurement
and
Press the function-mode button 4
until the indication for indirect
height measurement
on the display.
Pay attention that the measuring
tool is positioned at the same
height as the bottom measuring
point. Now, tilt the measuring tool
