surements.
DOL 51 must warm up for half an hour before being ready to measure (see the section of LED indication).
The sensor must be placed in middle of the livestock house or in the center between walls/filters when used in
an air cleaner. Make sure there is an adequate distance to walls and air inlets.
DOL 51 must not be suspended from the electric cable.
Figure 1: DOL 51 must be mounted vertically with the sensor pointing down; +/- 15° at a location with low vibra-
tion and, as far as possible, stable temperatures.
