6.3.7  Enter Device Address    ‘Adr’
This  function  allows  a  known  fieldbus  Device
Address  to  be  entered  and  allocated  to  the
indicator  input  selected  in  the  Edit  function.  To
enter  the  function  press  P  which  will  reveal  the
existing  two  digit  hexadecimal  address  with  one
digit  flashing  which  may  be  changed  by  operating
the 

  or 

  button.      When  set  as  required

operating  the  P  button  will  transfer  control  to  the
second  digit  that  may  be  adjusted  in  the  same
way.    When  both  digits  are  set  as  required
operating  the  E  button  will  enter  the  selection  and
return to the ‘Adr’ prompt in the edit sub-menu.

6.3.8  Enter Variable Identity    ‘id’
Enables  a  known  Variable  Identity  to  be  entered
and  allocated to the  indicator  input  selected  in  the
Edit  function.  To  enter  the  function  press  P  which
will  reveal  the  existing  two  digit  hexadecimal
address  with  one  digit  flashing  which  may  be
changed  by  operating  the 

  or 

  button.  When

set as required operating the P  button  will transfer
control to the second digit that may be adjusted in
the  same  way.    When  both  digits  are  set  as
required  operating  the  E  button  will  enter  the
selection  and  return  to  the  ‘id’  prompt  in  the  edit
sub-menu.

6.3.9  Decimal point position    ‘dP’
Defines  the  position  the  decimal  point  in  the
numeric  display.    To  enter  the  function  press  P
which  will  reveal  the  existing  decimal  point
position.    Operating  the 

  or 

  button  will  move

the  decimal  point  to  the  required  position,  omit  it,
or 

activate 

all 

the 

decimal 

points 

which

automatically  provides    maximum  resolution  in  the
display mode irrespective of the numeric value.
When  positioned  as  required,  operating  the  E
button will enter the selection and return to the ‘dP’
prompt in the edit sub-menu.

6.3.10  Configuration of bargraph display
‘bAr’
This  function  contains  three  sub-functions  that
enable  the  bargraph,  justify  its  position  and  define
the  relationship  between  the  bargraph  and  the
instrument’s numeric display.

Sub-function  ‘b.tYPE’  allows  the  bargraph  to  be
left,  centre  or  right  justified,  or  to  be  turned  off.
Sub-functions  ‘bArLo’  and  ‘bArhi’  define  the
listener’s  numeric  display  at  which  the  bargraph
starts and is at full scale.

The ‘bAr’ function may be selected from within the
edit  sub-menu  by  operating  the 

  or 

  button.

To enter the function press P which will display the
‘b.tYPE’  sub-function,  pressing  P  again  will  reveal
the existing bargraph justification.

The 

  or 

  button  will  scroll  through  the  four

options, 

when 

the 

required 

justification 

is

displayed,  pressing  E  will  enter  the  selection  and
return the display to the ‘b.tYPE’ prompt in the edit
sub-menu  from  which  ‘bArLo’  may  be  selected
using the 

 or 

 button.

‘bArLo’  defines  the  indicator’s  numeric  display  at
which  the  bargraph  starts,  to  enter  the  function
press P which will reveal the existing setting.   The
display may  be changed using the 

  or 

  button

to  adjust  the  flashing  digit  and  the  P  button  to
move control to  the  next  digit.   When  the  required
starting  display  has  been  selected,  press  E  to
return  to  the  ‘bArLo’  prompt  in  the  edit  sub-menu
from which the ‘bArHi’ function may be selected.

‘bArHi’  defines  the  indicator’s  numeric  display  at
which  the  bargraph  is  full  scale,  to  enter  the
function  press  P  which  will  reveal  the  existing
setting.   The display may be changed using the 

or 

  button  to  adjust  the  flashing  digit  and  the  P

button to move control to the next digit.  When the
required  display  has  been  selected,  press  E  twice
to  enter  the  new  values  and  return  to  the  ‘bAr’
prompt in the edit sub-menu.

Note:  If  the  ‘dP’  function  has  been  set  to  provide
automatic  maximum  resolution  irrespective  of  the
displayed  value,  it  may  be  necessary  to  manually
position  the  decimal  point  before  adjusting  ‘bArLo’
or  ‘bArHi’.      This  can  be  achieved  by  repeatedly
operating  the  P  button  until  the  activated  decimal
point  flashes,  the  decimal  point  can  then  be
positioned  using  either  the 

  or 

  button.

Pressing  the  P  button  again  will  return  control  to
one of the digits.

6.3.11  Scale numeric display    ‘SCALE’
A  scaling  factor  ‘Gain’  and  an  offset  ‘oFFSt’  may
be  applied  to  the  fieldbus  process  variable  using
this  function,  thus  allowing  the  indicator  to  display
the fieldbus process variable in alternative units.

The ‘SCALE’ function may be selected from within
the edit sub-menu by operating the 

 or 

 button.

To enter the function press P which will display the
‘GAin’  sub-function,  pressing  P  again  will  reveal
the  existing  gain  with  one  digit  flashing.  This
flashing  digit may  be  changed  by  operating  the 

or 

▲ button; when adjusted the 

P button will move

control  to  the  next  digit  or  to  the  decimal  point
which can be positioned using the 

 or 

 button.

When  ‘GAin’  has  been  set  to  the  required  value
operating  the  E  button  will  enter  the  selection  and
return  to  the  ‘GAin’  prompt  in  the  sub-menu  from
where  the  ‘oFFSt’  function  can  be  selected  using
the 

 or 

 button.
