UT Display
Units
The display units item selects the ‘text’ that will
be shown in the User menu item display
together with the analogue input value.

There are 27 ‘unit texts’, any of which can be
selected.
Alternatively select “- - -“ (dashes) for no units
text display; the analogue input value will be
displayed with no units.
For example:
If the displayed value for analogue input #1 is
pressure in bar; select “BAR” as the units text.
The display units ‘text’ has no influence on
the analogue input, or accossiating displayed
value, or used in any calculation or remote
communications.
Vo Value
Offset
This is the ‘value’ that must be displayed when
the signal is at minimum.
Example:
ACM type
3
ST:
4mA
Sensor:
4-20mA, 0-16bar
The display must show 0(zero) when the
signal is 4.0mA; set ‘Vo’ to 0(zero).
It is not possible to implement decimal
point values, in this instance set a value that is
‘1000’ times the required display value (1.0bar
= 1000mBar) then set ‘DF’ to display the value
at “divide by 1000 to one decimal place” - see
DF setting.
Vr Value
Range
This is the ‘value’ that must be displayed when
the signal is at maximum.
Example:
ACM type
3
ST:
4mA
Sensor:
4-20mA, 0-16bar
The display must show 16.0 when the signal is
20.0mA; set Vr to “16000”
It is not possible to implement decimal
point values, in this instance set a value that is
‘1000’ times the required display value (1.0bar
= 1000mBar) then set ‘DF’ to display the value
at “divide by 1000 to one decimal place” - see
DF setting.
DF
Display
Function
The display function determines how the
resulting ‘value’ (as determined by the ‘Vo’ and
‘Vr’ settings) is displayed in the User menu.
Standard DF Functions:
01: Show
value
directly
Value: 155 = Display: 155
02:
Divide ‘value’ by 10
Display to one decimal place
Value: 155 = Display: 15.5
03:
Divide ‘value’ by 100
Display to one decimal place
Value: 155 = Display: 1.6
04:
Divide ‘value’ by 1000
Display to one decimal place
Value: 155 = Display: 0.2
05:
Divide ‘value’ by 100
Display to two decimal places
Value: 155 = Display: 1.55
06:
Divide ‘value’ by 1000
Display to two decimal places
Value: 155 = Display: 0.16
For DF = 01 to 06 the value transmitted in
remote communications is always the direct
result of the set ‘Vo’ and ‘Vr’ settings; any
display DF function is ignored.
Any set FH (Fault High Level Set Point) or
FL (Fault Low Level Set Point) is referenced to
the direct result of the set ‘Vo’ and ‘Vr’
settings; any display DF function is ignored.
