7 Performing maintenance work
The OTT SVR 100 radar sensor is largely maintenance free. No adjustment or
calibration work is necessary. Likewise, it has no parts that have to be cyclically
replaced.
The following maintenance work should be performed at regular intervals, accord-
ing to your local conditions:
" Check the OTT SVR 100 for soiling (e.g. dense, dew-covered spiders’ webs or
insect nests can lead to negative impairment of the measured results). If neces-
sary, clean the sensor carefully (using standard mild and non-abrasive house-
hold cleaning agents and a soft sponge). Make sure that the swivel mount set-
ting does not change.
" Check that the measuring section is free of obstructions (for example flotsam or
overgrowing branches of trees and shrubs). Remove all obstructions.
Caution: Never open the OTT SVR 100 housing. There are no adjustments or
controls inside the housing.
