 Magnets have a strong magnetic force. When handling magnets, be
careful that they do not pinch your fingers or skin. Wear safety gloves, if
necessary.
 Magnets are brittle and can crack or shatter. Avoid magnets striking each
other or hard surfaces. Do not expose them to mechanical stress such as
drilling or grinding.
 Magnets and their coatings can contain nickel. Regular contact with them
can trigger nickel allergies. Avoid contact between magnets and bare skin.
In persons with a nickel allergy, contact can cause allergic reactions. If you
have a nickel allergy, you should not handle magnets.
 The magnetic field of a magnet can cause irreversible damage to objects.
Maintain a sufficient safety distance of at least 1 metre. Objects that can
be damaged include, for example:
- electronic devices such as hearing aids, laptops and monitors
- objects that contain iron, such as mechanical watches
- data carriers such as magnetic strips on credit cards, hard drives, etc.

Notice
In the factory setting, the trigonometric correction is activated
and unit is set to “m” (metres). To deactivate the trigonometric
correction and/or to change the unit to “ft” (feet), refer to
“Trigonometric correction / length unit” on page 20 and follow
the instructions provided there.
A complete LAP-TEQ Elevation distance measuring system consists of an
elevation unit mounted on a magnetic mount and a connected display system
such as LAP-TEQ Display PLUS or LAP-TEQ Motion System.
The elevation unit is designed for mounting on a flying frame, for example, and
measures the vertical distance between the zero line on the unit (see Your
device at a glance on page 12 ) and the surface beneath. This provides
information on the height of the speaker element and/or of the entire array.
The laser beam of the elevation unit is used for visually checking the area of
the surface to which the measurement is made. This allows you to determine
whether the end point of the measurement is correct.
The magnetic mounting bracket can also be used to mount a LAP-TEQ Sensor
PLUS. It is then possible to simultaneously measure the height and the vertical
alignment. Both values are shown simultaneously on the display. Use of a
LAP-TEQ Motion System as the display unit allows simultaneous adjustment
of the height and alignment.

► Connect the elevation unit (1) to the input “IN”, and the display unit (3)
using a standard 3-pin XLR cable (2).
There is no limit to the number of elevation units that can be connected
successively to a display unit. For example, three elevation units can be used
to check the correct orientation of a left and right PA system, as well as a
centre cluster.
To function correctly, the display unit must be connected to a elevation unit
using a standard XLR connection cable. The elevation unit is supplied with
power by means of the XLR cable. There are no rechargeable batteries or
other batteries in the elevation unit.
Notice
The length of the cable (2) between the display unit and the
elevation unit must not exceed 70 m.
For a distance greater than 70 m, you must use an XLR cable
with a larger cross section than 0.22 mm². This will reduce the
voltage drop along the cable route.

LAP-TEQ Elevation 19
5 Operation
5.1 Power on/off
Notice
Make sure that the reference point for the measurement is
correct. If the deviation to perpendicular is so large that the
laser detects an object, for example, this will result in an
incorrect measurement.
Check the condition of the device:
► Check for visible defects.
► Check to make sure that all parts of the device are firmly mounted.
Warning!
Danger of eye injuries from laser beams!
If the laser beam hits the eyes via optical devices, this can
result in irreparable damage.
► Never look into the laser or direct the laser beam onto
reflecting surfaces!
► Make sure that no one is within the effective range of the laser.
► Power on: Press the “Power” button on the display unit for about 3
seconds.
If the system has started up correctly, the red laser lights up and the current
distance is displayed. If a LAP-TEQ Sensor PLUS is connected in addition, the
current angle reading will be displayed simultaneously.
The measurement is refreshed continuously; in unfavourable conditions (cp.
Observe ambient conditions on page 25 ) this can take up to 3 seconds.
► Power off: Press the “Power” button on the display unit again.

Trigonometric correction / length unit

6 Trigonometric correction / length unit
Notice
In the factory setting, the length unit is set to “m” (metres). It can
be changed to “ft” (feet).
Notice
In the factory setting, the trigonometric correction is activated.
If the elevation unit cannot stabilise freely (e.g. due to cable tension), the
trigonometric correction can correct the deviation.
If the trigonometric correction is activated, a deviation from perpendicular is
corrected. The corrected value is shown on the display. If it is deactivated, the
actual reading of the crooked measurement, which could be incorrect, will be
displayed.
