General care

The Retroreflectometer is constructed for outdoor use in ordinary good weather conditions. It will stand moist weather with wet roads, but caution must be taken against rain or splashes and dirt from traffic. The LTL2000S(Q) Retroreflectometer is an optical instrument and shall be handled as such. Avoid shock and vibration if possible.

Note

Keep dust/protection window and light trap clean

Protection window

The protection window is located in the optical unit. The protection window is coated with a high efficiency anti reflection coating. Care must be taken not to damage this coating by cleaning. A fine brush can be used for removing loose particles/dust. If this is not sufficient the window should by cleaned using a soft paper tissue or cloth and some window cleaning liquid.

Battery

The LTL2000S(Q) Retroreflectometer is powered by a sealed 12V/3.5Ah lead acid battery, which under normal use requires no maintenance. However it is recommended to keep the battery fully charged. A fully charged battery is more capable of withstanding low tempera- ture and ageing.

Battery charger is provided as a standard accessory for charging the battery from mains. The output cable of the charger is equipped with a socket matching the connector in the instru- ment. Connect charger to mains and instrument. The red indicator will be switched on as long as the charging is in progress. Thereafter it switches periodically on and off. Normally the charging will take about 8 hours. Typically the battery achieves 90% of the capacity in 5 hours. No harm will result from leaving the charger connected for time in excess of the above indicated duration of the charging process. However, the battery must be disconnected from the charger when disconnecting the mains.

The battery is located in a compartment at the front of the tower. To replace the battery re- move the screws holding the right side cover plate, seen from behind. Remove the screws from the right hand side of the red front- and back cover plate. Remove the side cover plate. Remove the 2 nuts holding the clamp plate. Lift out the battery of its container. The battery can now be removed and replaced. Refit in reverse order.
