Push.the.sensor.cover.downwards.to.measure.the.air.
values.(see.fig . . 2) . . Pull.the.sensor.out.to.the.desired.
length.(see.fig . . 3.and.also.item.7:.Appliance.probe)
Direction of the sensor head:
There.is.a.marking.on.the.top.of.the.sensor.head . . This.
marking.must.point.against.the.direction.of.the.wind.
when. measuring. (see. fig . . 4/5) . . If. the. measurement.
has. been. performed. correctly,. the. measured. value.
appears.as.a.digital.value.on.the.display . . The.tempe-

Performing a multi-point mean value calculation
Press.the. .(Mean).button . . Mean.appears.and.you.
are. now. in. the. mode. for. calculating. a. multi-point.
mean. value. for. air. speed . . To. initiate. the. calculation.
for.temperature.or.volumetric.flow,.please.press.the.
.Flow/Temp.button .
As.soon.as.measurement.begins,.i .e . . as.soon.as.the.air.
speed.sensor.has.been.prepared.for.use.(push.the.sen-
sor.head.cover.downwards.and.set.the.marking.against.
the. wind. direction),. you. can. save. the. first. measured.
value.immediately.by.pressing.the.
