Your 400 instrument can be used for density measurement
functions, for dot area and dot gain measurement functions, and for
calculating measurement range. This chapter covers density
functions, and the following chapters cover dot and range functions,
respectively.
For density measurement, you need to set some measurement
parameters. You need to select:
Ÿ the desired measurement function (density); and
Ÿ the desired density measurement modeabsolute density, or
density minus reference
These parameters must be set for all types of density measurement.
Once these parameters are set, you can set your instrument to
evaluate measurement data two different ways:
Ÿ As a straight density measurement data. Viewing this data
requires no additional setup.
or
Ÿ As a density difference measurement data. This data shows you
the amount of difference between the measured density and a
pre-set reference density. To view data in this format, you need
to establish a reference measurement, and set up the instrument
for density difference readings (page 3-3).
