6.4.9 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’ enables 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

‘bArLo’ defines the listener’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

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.

the fieldbus process variable in alternative units.
