Description of product
LAP-TEQ PLUS 13
A complete LAP-TEQ PLUS angle measuring system consists of a display unit
and at least one sensor unit.
The sensor unit is designed for mounting on the topmost element of a line
array or of the bumper and measures the horizontal angle between its
longitudinal axis and the earth’s surface. This provides information on the
horizontal orientation of the speaker element and/or of the entire array.
The laser beam of the sensor unit is used for visually checking the area that is
supplied with sound. This allows you to determine whether the height of the
speaker system is optimally adjusted in order to distribute sound to a spectator
stand or a balcony.
If the laser beam hits a projection surface at a short distance, in addition to the
actual laser cross you will also be able to see a square window and several
points in extension to the cross axis. These artefacts are no longer visible with
the normal working distances of the system and do not constitute a defect.
The products LAP-TEQ Display, LAP-TEQ Sensor, LAP-TEQ Display PLUS
and LAP-TEQ Sensor PLUS are mutually compatible and can be operated
together in any combination.
LAP-TEQ Sensor is limited to operation with the base plate oriented
downward.
The calibration of a sensor unit from the display unit is possible only with the
combination LAP-TEQ Display PLUS and LAP-TEQ Sensor PLUS.
For calibration of LAP-TEQ Sensor PLUS without LAP-TEQ Display PLUS
please contact your sales partner.

Attention!
Danger of damage to device
► All components are maintenance free. Never open the
device; otherwise, the warranty will be voided.

First operation
LAP-TEQ PLUS 17
► Connect the display unit (1) and a sensor unit (3) using a standard 3-pin
XLR cable (2).
There is no limit to the number of sensor units that can be connected
successively to a display unit. For example, three sensor units can be used to
check the correct orientation of a left and right PA system, as well as a centre
cluster. Alternatively, one sensor unit can be attached permanently to each
bumper.
To function correctly, the display unit must be connected to a sensor unit using
a standard XLR connection cable. The sensor units are supplied with power by
means of the XLR cable. There are no rechargeable batteries or other
batteries in the sensor unit.
If the cable between the display and the sensor unit is longer than 75 m, this
will reduce the brightness of the laser. However, the measuring function will
not be affected.
For a distance greater than 75 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.

First operation
18 V-04/2018
Notice
The calibration cable included with the device can also be used
for a function check. Use of the calibration cable alone does not
start the calibration process.
► For mounting the sensor units, use the flange holes (1) on the bottom of
the housing.
For secure mounting on a bumper without a special LAP-TEQ holder, you can
use the optional TEQSAS LAP-TEQ magnetic holder. The sensor must be
bolted firmly to the flying frame or secured by suitable means against falling.
4.3 First operation
The sensor units are calibrated at the factory so that the base plate has to be
oriented downward. To use the sensor unit in a different position, it must be
recalibrated. Four positions are possible (90° grid on the longitudinal axis), see
page 24.
For the first-time use the base plate must be positioned downward.

5 Operation
5.1 Power on/off
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 for about 3 seconds.
If the system has started up correctly, the green laser lights up and the current
angle measurement is displayed.
The angle measurement is refreshed every 2 seconds. This integrated feature
is necessary to prevent the last digit in the display from changing constantly,
which could result for example from wind movement.
Notice
Pressing the “CAL” button on the display unit during operation
does not switch the sensor unit to calibration mode. Instead, a
short guide to calibration is displayed. The display automatically
switches back to the angle measurement after a few seconds.
► Power off: Press the “Power” button again.

Operation
20 V-04/2018
5.2 Display texts
If no cable or sensor unit or a defective cable is
connected to the display unit, the warning “no sensor”
appears on the display when the display unit is switched
on: Establish a correct connection between the display
unit and the sensor unit.
If the word “over” appears on the display, the
permissible measurement range of +/- 50° was
exceeded. This measurement range is sufficient for
practical application.
If three dashes appear on the display, the sensor unit is
being used in a position for which it was not calibrated.
After switching off the power the last measured reading
is written to the internal memory of the display unit.
When it is switched on again this reading appears in the
bottom line of the display. This facilitates the comparison
of identical horizontal alignment of the left and right PA
system.
