Height adjustment

Before using the LTL-X, notice that the operating panel can be adjusted in height for ergo-

nomic considerations. The height is adjusted by pressing the red knob on the front of the

instrument and at the same time lifting the handle on the operating panel. Release the knob

and continue lifting until the handle locks.

Measuring

Turn on the LTL-X by pressing and holding the ON/OFF button until the welcome

message appears. The display will then change to the measure mode. (An exception is when the

instrument is set to ask for user identification, see User select in this section).

Calibrate the instrument if necessary. See Calibration in this section.

Place the instrument on the road marking.

Press the green OK-button to take a measurement. A measurement will be finished in

approx. 1 sec.

When the measurement is complete, the R

value will be displayed. Data is automatically

transferred to the data log. If there is a problem with the measurement a warning icon or an

error icon will pop up (see Warnings and errors, see pg. 39) and an audible alarm will sound (if

enabled, see Sound settings).

Measurements taken with a battery voltage that is too low are rejected or marked in the log

and an error icon appears.

To print the last measurement data, press the PRINT/OUT button . The Print/Output

function must be set to Int. (See pg. 39). Printing can be stopped by pressing the PRINT/OUT

button or the ON/OFF button for approximately 0.5 sec.
