The starting conditions for a campaign are extremely important
Always power a laptop with a mains power unit, not just only by
battery.
It is extremely important that the cable is not moved during a
measurement campaign. Securely fix the cable as even a breeze
can move a dangling cable causing variance in the measurement.
Avoid leaving water drops on the fastener clips.
6.1 Starting conditions
The following conditions must be fulfilled before a measurement can
be started:
1. Prepare
the
described
chapters. Then apply a surplus
of water drops on the sample
with a pipette (photo right). This
will create equal conditions.
2. The initial water content of the
completely saturated sample is
estimated. It can be calculated if
the soil type is definitely known
(more in chapter 6.4).
3. The sample must be protected
from direct sunlight, air currents
or
extreme
