Detection speed (mm/min)

At the start of the measurement the sample stage is first moved upwards. The contact
between the plate and the surface of the liquid is registered owing to the change in
force; the height position is stored for the measurement. The search speed is the
speed at which the sample stage moves upwards to find the liquid surface. The set
value of 20 mm/min is normally suitable. You should not increase it by much as
otherwise the detected surface height becomes less accurate.
7.2.3

Immersion depth (mm)

This is the distance by which the sample stage is moved upwards after detection of the
surface in order to immerse the plate in the liquid. This immersion ensures a more
rapid and better wetting of the plate surface. The plate is returned to the height of the
liquid surface for making the measurement. The standard value of 3 mm has proven
itself in practice. With viscous samples, emulsions and dispersions and with solutions
whose constituents could dry out on the plate this immersion should be prevented,
(immersion depth 0 mm) as otherwise measuring errors could occur.
