Once  you  have  reached  the  relevant  menu,  scroll  through  the  parameters, 
and  enter  the  necessary  information.  To  enter  the  information,  use  the  UP 
and DOWN keys to increment or decrement the digit, and the ENTER key 
to  shift  the  flashing  digit  to  the  next  position,  once  you  have  completed 
entering the value required pressing the ENTER button again will save the 
value. 
When  you  have  finished,  press  CANCEL  to  go  back  to  the  previous  level. 
When  you  have  reached  the  top  level,  then  the  IMP+
IMP+IMP+
IMP+  will  ask  for 
confirmation before allowing you to go back into run mode. This is done by 
pressing ENTER at the display prompt.

When first installing the IMP+
IMP+IMP+
IMP+, 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+
IMP+IMP+
IMP+ 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. All relays are set OFF. 
 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+
IMP+IMP+
IMP+  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  of  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.
