u
Take the batteries out of the measuring tool when you are not using it
for a prolonged period of time.
The batteries can corrode and self-dis-
charge during prolonged storage in the measuring tool.
u
Make sure to switch the laser off before changing the batteries.
An
accidentally switched on laser can blind other persons.
Mounting the Leg Extension
Slide the leg extension
(21)
from the front onto the fold-out leg
(1)
. Slide
the leg extension as far as possible over the joint of the measuring tool.
Operation
Starting Operation
u
Protect the measuring tool from moisture and direct sunlight.
u
Do not expose the measuring tool to any extreme temperatures or
variations in temperature.
For example, do not leave it in a car for ex-
tended periods of time. In case of large variations in temperature, allow
the measuring tool to adjust to the ambient temperature before putting it
into operation. The precision of the measuring tool may be compromised
if exposed to extreme temperatures or variations in temperature.
u
Keep the supporting surfaces and contact edges of the measuring
tool clean. Protect the measuring tool against shock and impact.
Dirt
particles or deformations can lead to faulty measurements.
u
Avoid hard knocks to the measuring tool or dropping it.
Always carry
out an accuracy check before continuing work if the measuring tool has
been subjected to severe external influences (see "Accuracy Check and
Calibration of the Measuring Tool", page 23).
Switching On and Off
u
Never leave the measuring tool unattended when switched on, and
ensure the measuring tool is switched off after use.
Others may be
blinded by the laser beam.
To
switch on
the measuring tool, press the on/off button
(14)
.
If the indicator
H
(a)
lights up, a value from the last measurement is still
saved. This value can be deleted by
briefly
pressing the on/off button
(14)
.
To
switch off
the measuring tool, press the on/off button
(14)
.
When no activity is performed on the measuring tool for approx.
30
min, the
measuring tool automatically switches off to save the batteries.
Aligning with the Spirit Levels
The measuring tool can be aligned horizontally with spirit level
(9)
and ver-
tically with spirit level
(10)
.
The measuring tool can also be used as a carpenter’s spirit level for checking
vertical and horizontal lines. For this, place or hold the measuring tool
against the surface subject to checking.
Rotating the Display
When you rotate the measuring tool 180°, the display will also rotate auto-
matically to make the displayed value easier to read.
"Normal measuring" Operating Mode
After switching on, the measuring tool is always in "normal measuring" oper-
ating mode.
In "Normal Measuring" mode, angle measurement and grade measurement
are carried out simultaneously.
Measuring Angles (see figures C–D)
Place the fold-out leg
(1)
and the base leg
(4)
flat on the surfaces adjacent
to the angle. The displayed measured value
(g)
corresponds with the in-
terior angle
w
between the base leg and the fold-out leg.
This measured value is shown on the display
(7)
until you change the angle
between fold-out leg
(1)
and base leg
(4)
.
Transferring Angles (see figure E)
Measure the angle to be transferred by placing the fold-out leg and base leg
on the target angle.
The position of the legs can be locked mechanically by tightening the locking
wheel
(3)
. The displayed value is not saved.
Place the measuring tool in the required position against the workpiece. Use
the legs as a straight edge to transfer the angle.
Storing the Measured Value
Press the
Hold
(17)
button to store (
H
) the current measured value
(g)
.
The indicator
(a)
flashes in the display for confirmation. The currently dis-
played value is frozen and will not change even when the leg is moved. If you
press the memory button
Hold
again, the indicator
(a)
will be shown per-
manently on the display. The displayed value will change depending on the
leg movement. The previously frozen value is now saved in the background.
If the memory button
Hold
(17)
is pressed again, the previously saved value
is displayed and the indicator
(a)
flashes.
To delete the contents of the memory, briefly press the on/off button
(14)
.
To be able to save a new value, a previously saved value has to be deleted.
Saved values cannot be overwritten.
