Getting started
Insert battery: Before using the LTL3000 instrument make sure that the battery is charged and inserted in the
battery slot on the side of the instrument.
Turn on: Press the green button on the handle of the LTL3000 instrument. After 10-15 seconds, the system has
booted, and the instrument is ready for use.
Stand-by: The LTL3000 automatically switches to stand-by mode if the instrument has not been used for a
specific amount of time. From stand-by mode the instrument is instantly ready when pressing the green button on
the handle.
Switch off: press the X-button on the handle of the LTL3000 and then press ‘Shutdown’ in the menu on the touch
screen, and the instrument will switch off. Note: If not properly switched off, the instrument will continue to
consume battery in standby mode.
Calibration procedure
Before a calibration is carried out make sure that the calibration unit is clean and undamaged.
Reference RL calibration (recommended daily)
To calibrate the LTL3000 use the RL calibration target delivered with the instrument.
Calibrate the RL value by following these steps:
• Select ‘Calibrate’ from the main menu.
• Type in the RL-calibration value printed on the calibration target sticker.
• Place the calibration target under the LTL3000 (in the front) and press ‘Calibrate RL’ on the screen. Note: the
pins on the calibration target fit into the slots underneath the LTL3000 instrument.
•Wait for success confirmation and remove the calibration unit
Reference Qd calibration (when needed):
The instrument is factory calibrated for the Qd value and thus Qd should only be recalibrated when needed.
The calibration can be verified by performing a Qd measurement on the Qd calibration marking delivered with the
instrument. If the reading is within a few percent recalibration is not required. Qd calibration requires the Qd calibration
marking. The instrument will warn about this fact before calibration. Note: Be aware that it is NOT possible to recover
the factory calibration if the Qd value is recalibrated.
To calibrate the Qd value follow these steps:
•Select ‘Calibrate’ from the main menu.
•Type in the Qd calibration value printed on the calibration target sticker.
•Place the LTL3000 all the way back on the Qd calibration target facing in the direction indicated.
•Press ‘Calibrate Qd’ on the screen.
•Wait for success confirmation.
Perform a measurement
Select ‘Measure’ from the main menu, and the instrument is now ready to perform a measurement.
Place the LTL3000 instrument on top of the specific road markings you want to measure and press the green button on
the instrument handle. NOTE. Make sure that the instrument is positioned correctly on the road marking. The two wear
plates in front of the instrument and the end of the instrument should be on the mark when measuring.
Wait a second until the reading is shown on the display. The measurement data is automatically saved by the
LTL3000 instrument. You can now continue to conduct another measurement.
If you want to switch to another measurement series, choose the relevant series from the drop-down menu or
select it in the Series menu and continue with your measurements.
