LTL2000S(Q) Retroreflectometer
18
The LTL2000S(Q) is factory calibrated. Nevertheless start important measurements with a
calibration. Study the Retroreflectometer status and error messages if any. See also Section 4
– Maintenance (page 25).
When the battery voltage becomes low a warning is shown in the display (W). It is still possi-
ble to take measurements but when the voltage drops further, readings can be erroneous.
If in doubt whether the readings are correct make a control measurement on the calibration
unit.
Note
Keep light trap, optical-protection window and ceramics on calibration unit clean.
Keep battery fully charged. A well charged battery is more resistant to ageing and damage by
freezing
