Maintenance
Service:
Service to the LTL3000 instrument must be done by DELTA or DELTA trained personal.
All spare parts (except for battery and charger) must be supplied only by DELTA.
General care:
The LTL3000 is constructed for outdoor use in fair weather conditions. The retroreflectometer can withstand
moist weather, but caution must be taken against rain or splashes and dirt from traffic. Even though the
LTL3000 is a robust instrument, it is also an optical instrument and must be handled with care:
•
Avoid exposing the instrument to high mechanical shocks and vibrations.
•
Avoid exposing the instrument to rapidly changing temperatures.
•
When not in use, store the instrument in its case in a clean and dry environment.
When the instrument is not in use, turn off the instrument and fold the screen cover down to protect the touch
screen. If the battery is not properly turned off, it will deplete the battery during storage.
You may clean the LTL3000 instrument and the touch screen using a soft, clean linen cloth with mild
detergent.
Battery:
A substantial drop in obtainable measurements on a fully charged battery indicates that the battery is worn
out and must be renewed.
For your safety:
Do not expose the battery to heat or flames:
Danger of explosion.
Do not place the battery on a heater or
expose to direct sunlight for long periods.
The battery can be stored within a temperature range between -10°C to +60°C (14°F to 140°F), but we
recommend storage between 0°C to +30°C (32°F to 86°F), due to lifetime considerations of the battery.
Allow a warm battery to cool before charging. When handling or storing the battery take special care to avoid
possible short circuiting the battery contacts.
See further details in the battery user guide.
Safety precautions:
•
The battery should be protected against impact. Do not open the battery.
•
Store the battery in a dry and clean place.
•
Due to environmental protection do not dispose the battery with household waste.
