For continuous measurements, press function
mode button
4
until the indicator for continuous
measurement appears on the display. To start
the continuous measurement, press the 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 plumb
lines or 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 diago-
nals.
The current measuring value is dis-
played in the result line
c
. The max-
imal (
“max”
) and the minimal
(
“min”
) measuring value are dis-
played 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 minimal and maximal values are de-
leted by pressing the button for clearing the inter-
nal memory
8
.
Pressing the measuring button
2
ends the continu-
ous measurement. The last measured value is dis-
played in the result line
c
. Pressing the measuring
button
2
again restarts a continuous measuring
run.
Continuous measurement automatically switches
off after 5 min. The last measured value remains in-
dicated in the result line
c
.
Indirect Distance Measurement
The indirect distance measurement is used to
measure distances that cannot be measured di-
rectly 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 ver-
tical direction. Any deviation in horizontal direction
leads to measuring errors.
The laser beam remains switched on between the
individual measurements.
For indirect length measurements, three measur-
ing modes are available. Each measuring mode
can be used for determining different distances.
a) Indirect height measurement (see figure C)
Press the function-mode button
4
until the indica-
tion for indirect height measurement
appears
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 around the reference
plane and measure distance
“1”
as for a length
measurement.
Upon completion of the measure-
ment, the result for the sought dis-
tance
“X”
is displayed in the result
line
c
. The measuring values for
the distance
“1”
and the angle
“
α
”
are displayed in the measured-val-
ue lines
a
.
b) Double indirect height measurement
(see figure D)
Press the function-mode button
4
until the indica-
tion for double indirect height measurement ap-
pears on the display.
Measure distances
“1”
and
“2”
in this sequence as
for a length measurement.
Upon completion of the measure-
ment, the result for the sought dis-
tance
“X”
is displayed in the result
line
c
. The measuring values for
the distances
“1”
,
“2”
and the an-
gle
“
α
”
are displayed in the meas-
ured-value lines
a
.
Pay attention that the reference plane of the meas-
urement (e.g. the rear edge of the measuring tool)
remains exactly at the same location for all individ-
ual measurements within a measuring sequence.
c) Indirect length measurement (see figure E)
Press the function-mode button
4
until the indica-
tion for indirect length measurement
appears
on the display.
Pay attention that the measuring tool is positioned
at the same height as the sought measuring point.
Now, tilt the measuring tool around the reference
plane and measure distance
“1”
as for a length
measurement.
Upon completion of the measure-
ment, the result for the sought dis-
tance
“X”
is displayed in the result
line
c
. The measuring values for
the distance
“1”
and the angle
“
α
”
are displayed in the measured-val-
ue lines
a
.
Wall Surface Measurement (see figure F)
The wall surface measurement is used to deter-
mine the sum of several individual surfaces with a
common height.
In the example shown, the total surface of several
walls that have the same room height
A
, but differ-
ent lengths
B
, are to be determined.
For wall surface measurements, press the function-
mode button
4
until the indicator for wall surface
measurement
appears on the display.
Measure the room height
A
as for a length meas-
urement. The measured value (
“cst”
) is displayed
in the top measured-value line
a
. The laser remains
switched on.
