Images - SDT VIGILANT User Manual

New Units can also be defined, which can be associated to the predefined or to new Properties created
by the user. The following screen shows the fields that define the Units.
Option Description
Label Text that identifies unequivocally the Unit within the system. It can contain numbers,
upper and lower characters. Special characters or blank spaces are not allowed.
Property Sets the Property associated to the Unit.
dB unit Sets if the Unit will be used with a linear or a logarithmic scale (dBs).
Factor Sets the factor that converts the default Unit of the Property into the one being configured.
The default Unit is shown at the right of this field, and on its definition is set with a
conversion factor of 1.
Offset Defines the offset applied to the measurement to convert its units into the Unit being
configured. This value will be subtracted from the measurement after applying the Unit
factor.
dB Sets the reference value (in default Units) for the dB calculation. This field is only available
Reference in case decibel units are selected.
dB Factor Sets the scaling factor to be applied to decibel units (10 or 20). This field is only available in
case decibel units are selected.
Units can be configured to behave linearly or logarithmically with respect to the
reference unit. For some Units, a proportional scaling transformation is used, via the
equation of a line, using a slope and an offset. Decibel scales use a logarithmic
transformation, based on the relationship between the new unit and the reference
unit. A multiplicative factor is applied to the logarithm which is defined on the dB
factor.
