peratures, then no further pretreatment is needed.
Before every new measurement at a lower tempera-
4
ture than just indicated by the thermometer, there
has to be proceeded as described at point 2. In case
that parts of separated filling are noticed, follow once
more point 1 and 2.
Normally the thermometer is calibrated for total im-
5
mersion, i. e. it shows exactly, if it will be immersed
up to the reading point into the medium to be measu-
red. At temperatures from about +50
the reading point should be above the medium a little
bit to avoid that liquid distils colourless in the safety
chamber (source of errors). The somewhat emerged
part of the liquid results a small error, which can be
determined by a correction of the emergent column.
A partial immersion instrument should be handled
6
according to above points 1 to 4 as well. The destil-
late as mentioned in point 5 however must not be
feared. The stipulated Average Temperature of
Emergent Column has yet to be kept exactly.
The thermometer should be kept upright in order to
7
avoid a separation of the liquid column. A vertical po-
sition of the instruments is also recommended, if it is
in longer use.
