Factory Defaults
When first installing the IMP+ i.s., or subsequently moving or using the unit
on a new application, before proceeding to program the unit for its intended
application it is recommended that you ensure that all parameters are at their
default values by completing a Factory Defaults P930, as described in
Chapter 5 Parameter Guide.
When you first switch the IMP+ i.s. on, it will be reading the distance from
the face of the transducer to the material surface. It will be indicating in
metres, as shown on the display.
TIP
In some applications, it is simplest to empty the
vessel, take a reading from the Imp for distance
and then setup the empty level to this figure.
Once you are satisfied with the installation, and the IMP+ i.s. is reading what
you would expect in terms of distance from the face of the transducer to the
material level, then you can proceed with programming, for the intended
application. It is sensible to program all the required parameters at the same
time. The system will be then set-up.
Note that the span is automatically calculated from the empty level, so the
empty level should be entered first.
