DELTA
SECTION 5: Maintenance
General care
The RetroSign GRX 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 RetroSign GRX 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.
Front lens
The lens does not need special maintenance. If dirty carefully moist the lens with ordinary window
cleaning liquid and clean it with a soft linen cloth. If damaged send the instrument to DELTA or one of
our authorized service dealers for repair.
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 precaution:
•
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.
Battery charger
Keep the battery charger clean by blowing compressed air on charger vents and wiping the charger
housing with a damp cloth. Contamination may result in electric shock or fire. Make sure the battery
charger is unplugged before cleaning it.
Calibration target
To make sure that the calibration of the retroreflectometer is correct it is important that the surface on
the calibration target is clean and undamaged. Keep the calibration target protected, and be careful
not to touch the calibration target (reflective side).
If the surface is stained, scratched, or broken the calibration target must be replaced. A replacement
calibration reference can be purchased from DELTA and changed by the user by unscrewing two
screws and replace the damaged calibration reference.
