In ExPresso Mini the Delta Mode can be
activated.
Taken measurements will then be compared
to reference densities, pre-set in the Density
Reference Setup.
The reference data and the result will be dis-
played. The reference line is always the refer-
ence value and the corresponding tolerance.
The figure describes the situation inside and
outside of the tolerance and the situation
outside of the graphic space.
