Operation
Initial Operation
Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or variations in
temperature.
As an example, do not leave it in vehicles for a long time. In case of
large variations in temperature, allow the measuring tool to adjust to the ambient
temperature before putting it into operation. In case of extreme temperatures or
variations in temperature, the accuracy of the measuring tool can be impaired.
Setting Up the Measuring Tool (see figure A)
Set up the measuring tool at least 5 m away from the line laser. Switch on the pulse
function of the line laser. Select an operating mode on the line laser where either only
one horizontal or vertical laser plane is generated.
Note:
Do not select an operating mode with both horizontal and vertical laser plane
(cross-line operation), as otherwise faulty height indications of the laser beam may
occur.
Position the measuring tool in such a manner that the laser beam can reach the recep-
tion area
10
. Align the measuring tool in such a manner that the laser beam runs lat-
erally through the reception area (as shown in the figure).
Switching On and Off
A loud audio signal sounds when switching on the measuring tool. Therefore,
keep the measuring tool away from your ear or other persons when switching
on.
The loud audio signal can cause hearing defects.
To
switch on
the measuring tool, press the On/Off button
2
. All display indicators as
well as all LEDs light up briefly and an audio signal sounds.
To
switch off
the measuring tool, press the On/Off button
2
again. Before switching
off, all LEDs briefly light up.
When no button is pressed on the measuring tool for approx. 20 minutes and when no
laser beam reaches the reception area
10
for 20 minutes, the measuring tool auto-
matically switches off in order to save the battery. The switching off is indicated by
brief lighting up of all LEDs.
Selecting the Setting of the Centre Indicator
You can use button
1
to specify the accuracy with which the position of the laser beam
is indicated as “centred” on the reception area:
– Measuring accuracy “Fine” (indication
g
on the display),
– Measuring accuracy “Coarse” (indication
f
on the display).
Whenever switching on the measuring tool, the accuracy level “coarse” is set.
