ample, move a desired distance away from a wall while read-
ing off the current distance at all times.
For continuous measurements, repeatedly press the button
for changing function (4) until the indicator for continuous
measurement appears on the display. To start the continu-
ous measurement, press the measuring button (2).
The minimum measurement is used to determine the
shortest distance from a fixed reference point. For example,
it can help in determining verticals or horizontals.
The maximum measurement is used to determine the
greatest distance from a fixed reference point. For example,
it can help in determining diagonals.
The current measured value is shown in the
result line (c). The maximum ("max") and min-
imum ("min") measured value appear in the
measured value lines (a). It is then always
overwritten if the current length measurement
value is smaller or larger than the previous minimum or max-
imum value.
Press the memory deletion button (8) to erase the previous
minimum or maximum values.
Press the measuring button (2) to end the continuous meas-
urement. The last measured value is displayed in the result
line (c). Pressing the measuring button (2) again starts a
new continuous measurement.
Continuous measurement automatically switches off after
five minutes. The last measured value remains displayed in
the result line (c).
Indirect distance measurement
The indirect distance measurement is used to determine dis-
tances that cannot be measured directly, due to an obstacle
that would impede the path beam or the absence of a target
surface that could serve as a reflector. This measuring pro-
cedure can only be employed vertically. Any horizontal devi-
ation will lead to measurement errors.
The laser beam remains switched on between the individual
measurements.
For indirect length measurements, three measuring modes
are available. Each measuring mode can be used for determ-
ining different distances.
a) Indirect height measurement (see figure C)
Repeatedly press the button for changing function (4) until
the indicator for indirect height measurement
the display.
Ensure that the measuring tool is at the same height as the
lower measuring point. Then tilt the measuring tool around
the reference level and measure distance (1) as for a length
measurement.
Once the measurement is complete, the result
for the required distance "X" is displayed in
the result line (c). The measured values for dis-
tance "1" and angle "α" can be found in the
measured value lines (a).

b) Double indirect height measurement (see figure D)
Repeatedly press the button for changing function (4) until
the indicator for double indirect height measurement
pears on the display.
Measure distances 1 and 2 in succession as for a length
measurement.
Once the measurement is complete, the result
for the required distance X is displayed in the
result row (c). The measured values for dis-
tances 1 and 2 and angle α can be found in the
measured value rows (a).
Ensure that the reference level for the measurement (e.g.
the rear edge of the measuring tool) remains in exactly the
same place for all the individual measurements in a single
measuring process.
c) Indirect length measurement (see figure E)
Repeatedly press the button for changing function (4) until
the indicator for indirect length measurement
the display.
Ensure that the measuring tool is at the same height as the
required measuring point. Then tilt the measuring tool
around the reference level and measure distance "1" as for a
length measurement.
Once the measurement is complete, the result
for the required distance "X" is displayed in
the result line (c). The measured values for dis-
tance "1" and angle "α" can be found in the
measured value lines (a).
Wall area measurement (see figure F)
The wall area measurement is used to determine the sum of
multiple individual areas with a common height.
In the illustrated example, the total area of several walls that
have the same ceiling height A but different lengths B is to
be determined.
For wall area measurements, repeatedly press the button for
changing function (4) until the indicator for wall area meas-
urement appears on the display.
Measure the ceiling height A as with a length measurement.
The measured value ("cst") is displayed in the top measured
value line (a). The laser remains switched on.
Then measure the length B
The area is automatically calculated and dis-
appears on
1
played in the result line (c). The last measured
value for length can be found in the middle
measured value line.(a). The laser remains
switched on.
Now measure the length B
The individual measured value displayed in the
middle measured value line (a) is added to the
length B
displayed in the bottom measured value line
(a)) is multiplied by the saved height A. The total area value
is displayed in the result line (c).
You can measure any number of lengths B
automatically added and multiplied by the height A.
