Digital laser
measure
GLM 150 C
Max. transmission power 8 mW
A) For measurements from the front edge of the measuring tool,
this applies for high reflectivity of the target (e.g. a white-
painted wall), weak backlighting and 25°C operating temperat-
ure. In addition, a deviation of ±0.05mm/m must be taken into
account.
B) For measurements from the front edge of the measuring tool,
this applies for high reflectivity of the target (e.g. a white-
painted wall), and strong backlighting. In addition, a deviation
of ±0.15 mm/m must be taken into account.
C) After calibration at 0° and 90°. Additional pitch error of max.
±0.01°/degree up to 45°. The measurement accuracy refers to
the three orientations of the grade measurement calibration,
see figure H
D) At an operating temperature of 25 °C
E) The left-hand side of the measuring tool serves as the reference
level for grade measurement.
F) In continuous measurement mode, the max. operating temper-
ature is +40 °C.
G) non-conductive soiling only, whereby occasional temporary
conductivity caused by condensation is expected
H) The automatic switch-off time can be adjusted (to two, five, ten
minutes or never).
I) When using Bluetooth® Low Energy devices, it may not be pos-
sible to establish a connection depending on the model and op-
erating system. Bluetooth® tools must support the GATT profile.
The serial number (15) on the type plate is used to clearly identify
your measuring tool.
Fitting
Inserting/Changing the Batteries
It is recommended that you use alkaline manganese batter-
ies to operate the measuring tool.
– Press the release button (7) and fold the measuring pin
(8) out by 180°.
– To open the battery compartment cover (16), fold the
rotary lock (21) upwards and turn it anti-clockwise by
one quarter-turn. Lift up the battery compartment cover
using the rotary lock. Insert the batteries. When inserting
the batteries, ensure that the polarity is correct according
to the illustration on the inside of the battery compart-
ment.
u Take the batteries out of the measuring tool when you
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage.
u Note: TrackMyTools can only be used when batteries are
inserted.
Operation
Start-Up
u Never leave the measuring tool unattended when
switched on, and ensure the measuring tool is
switched off after use. Others may be dazzled by the
laser beam.
u Protect the measuring tool from moisture and direct
sunlight.
u Do not expose the measuring tool to any extreme tem-
peratures or variations in temperature. For example,
do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measur-
ing tool to adjust to the ambient temperature before put-
ting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperat-
ures or variations in temperature.
u Avoid substantial knocks to the measuring tool and
avoid 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 of the distance measurement", page18).
u The measuring tool is equipped with a wireless inter-
face. Local operating restrictions, e.g. in aeroplanes
or hospitals, must be observed.
Switching On/Off
During work, ensure that the reception lens (18), the laser
beam output (19) and the camera (20) are not closed off or
covered, otherwise correct measurement will not be pos-
sible.
– To switch on the measuring tool and the laser, briefly
press the front or side measuring button (2) [ ].
– To switch on the measuring tool without the laser, briefly
press the on/off/delete button (9) [ ].
u Do not direct the laser beam at persons or animals and
do not stare into the laser beam yourself (even from a
distance).
To switch off the laser, briefly press the on/off/delete but-
ton (9) [ ].
To switch off the camera, press the viewfinder button (10).
To switch off the measuring tool, press and hold the on/off/
delete button (9) [ ].
The measured values and device settings in the memory are
retained when you switch the measuring tool off.
Camera
The camera (20) is switched on automatically when the
measuring tool is switched on for the first time. To switch it
off, press the viewfinder button (10).
The camera setting (on/off) is saved when the measuring
tool is switched off.
Optimising visibility of the laser point
Especially when using the measuring tool outdoors, in sun-
light and also over long distances indoors, the laser point
may not be visible. The visibility of the laser point/measure-
ment point can additionally be improved in order to connect
the camera by:
– Setting the display brightness (tool settings)
– Using the zoom by pressing the button (5).
