INTRODUCTION

Introduction

This manual covers both LTL2000S and LTL2000SQ. Some functions will only be available on LTL2000SQ and will be printed in blue colour.

The LTL2000S is a portable field instrument, intended for measuring the reflection properties of road markings “Rl” as seen in the vehicle headlight illumination.

To measure the Rl properties (coefficient of retro reflected luminance) the road is illuminated at an angle of 1.24 deg. and the reflected light is measured at an angle of 2.29 deg.

The LTL2000SQ is intended for measuring both “Rl” and the lightness of road surfaces and road markings “Qd” as seen under daylight conditions or with stationary lighting.

To measure the Qd properties (the luminance coefficient under diffuse illumination) the road is illuminated with a diffuse source and the reflected light is again measured at an angle of 2.29 deg.

An observation angle of 2.29 deg corresponds to an observational distance of 30 metre, thus relevant for a motorist viewing situation under normal driving conditions.

Rl and Qd is important factors in the ON-SITEquality control of road markings.

The operation of the instrument is very simple and requires a minimum of instruction. An er- ror message or warning is given in case of unreliable or erroneous measurement.

The LTL2000S(Q) measures the Rl and Qd values according to international agreements. Re- sults are presented in plain English on a LCD display. The built-in printer and non-volatile memory provides on site registration of measurements with corresponding date and time.
