row shows the resulting distance between the two measured points .
Press and hold the button to display additional information about the
measurement, such as the horizontal distance , the height difference
between the measured points , or the included angle .
)
Measure to the top target point first. This point must lie behind the
bottom target point. If this is not the case, an error message appears in the
display.
Profile measurement
This function is used to measure profiles and terrain sections. After measu-
ring a reference point with a known height (e.g. bench mark or floor), the
height and horizontal distance to the instrument are displayed for each
following point.
)
We recommend using a tripod!
Press the key five times.
The following symbol appears on the display: .
With and enter the known height of the reference point (e.g. -
4,000 m in a construction system) and confirm with . The following
symbol then appears on the display: .
Now aim the instrument at the height reference point and press the
key - the gradient and distance are measured. The instrument is then ready
to measure profile points
.
Measure the profile points by pressing the key. The horizontal
distance from the instrument to the measured point and the height
of the point are displayed.
Press to exit the function.
)
If the tripod and the instrument are moved, always restart the func-
tion and measure the height reference point again before continuing to
measure!
Storage of constants / historical storage
Storage of a constant
You can store and recall a frequently used value e.g. height of a room.
Measure the desired distance, press and hold the
button until the
device beeps to confirm storage.
Recalling the constant
Press this button once to recall the constant and then press the
button to enter it into your calculation.
Historical storage
Press this button twice and the previous 30 results (measurements
or calculated results) are shown in reverse order.
The
and buttons can be used for navigation.
Press this button to use a result from the summary line for further
calculations.
Pressing the
and buttons at the same time erases all the values
in historical storage.
Timer (self-triggering)
Press this button to set a 5-second time delay.
or
Press and hold down this button until the desired time delay is
reached (max. 60 seconds).
Once the key is released with the laser activated, the remaining seconds
until measurement (e.g. 59, 58, 57...) are displayed in a countdown. The last
5 seconds are counted down with a beep. After the last beep the measu-
rement is taken and the value is displayed.
)
The timer can be used for all measurements.
