Take the sample ring with the soil out
of the transportation box.
Take lids off and clean the sample ring.
Put the sample ring on the ring with
porous plate.
Put both rings into the trough.
Fill in 2 cm (1 in) of degassed water
with similar ionic composition as
the soil sample.
Raise the water level almost to the
sample height (recommended times
see below)
Do not pour water on the sample –
you may trap air.
Use the time table below for a reference
to determine how long samples take to
saturate.
