DELTA LTL2000S(Q) Retroreflectometer 1 SECTION 1 INTRODUCTION Introduction This manual covers both LTL2000S and LTL2000SQ. Some functions will only be available on LTL2000SQ and will be printed in blue colour.
DELTA LTL2000S(Q) Retroreflectometer 2 Serial communication on RS232 port gives exte nded comm and, calibration, diagnostics and data dump facilities. The LTL2000S(Q) is powered by a rechargeable lead acid battery, giving several hours of measurement capacity.
DELTA LTL2000S(Q) Retroreflectometer 3 Getting started Buttons M e a s u r e Me n u En t er Hom e O F F C ali b r at e Pr i n t Sc ro l l d o w n S c r ol l u p O N Measuring Turn the instrument on by pressing and holding the button until the LCD shows: Calibrate the instrument if necessary, see Calibr ation page 6 .
DELTA LTL2000S(Q) Retroreflectometer 4 scroll through the status list to see the possible cause of the problem. For further description on the error messages see Status Display page 19. Alternatively or select the menu Print Status to print a complete instrument status.
DELTA LTL2000S(Q) Retroreflectometer 5 the Mean calculation function is enabled and there is m ore than 1 measurement in the calcula- tion then the number of meas urements is shown first.
DELTA LTL2000S(Q) Retroreflectometer 6 Calibration - LTL2000S A calibration should always be carried out befo re starting a new seri es of measurements. Calibration is done by placing the calibration unit underneath th e instrument between the rails. The easiest way to place the unit is to tilt the instrument backwards.
DELTA LTL2000S(Q) Retroreflectometer 7 The display shows: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Step 8 To verify the calibration do a Rl measurem ent on the normal before rem oving the normal in step 8. To document the calibration press the key to print.
DELTA LTL2000S(Q) Retroreflectometer 8 Calibration - LTL2000SQ A calibration should always be carried out befo re starting a new seri es of measurements. The LTL2000SQ is supplied with two calibration units. One for Rl and one for Qd. The order of R1 / Qd calibration is not cr itical .
DELTA LTL2000S(Q) Retroreflectometer 9 If the key is pressed the calibration result is printed. In the example above the Qd f unction is now calibrated to a Qd value of 215. If an error is detected during the calibration procedur e then the display will indicate this.
DELTA LTL2000S(Q) Retroreflectometer 10 Remember : Recharge battery when possible. Never le ave battery discharged for longer periods of time. Keep protection window, light tr ap and calibration unit clean. LTL2000S(Q) is an optical precision instrument, handle with care.
DELTA LTL2000S(Q) Retroreflectometer 11 SECTION 2 GENERAL INFORMATION Rl Measurement The Rl part of the LTL2000S(Q) Retroreflectometer measures the Rl (coefficient of retro re- flected luminance) parameter. The Rl param ete r repres ents the brightne ss of the road mark- ings seen by drivers of motor vehicles by headlight illumination.
DELTA LTL2000S(Q) Retroreflectometer 12 The illuminations field with a length of 200 mm length and 43 mm wide gives a large measur- ing measurement field of 85 cm 2 .
