Function check
Before commissioning the measurement point make sure that all final checks have been carried out:
• Checklist "Post-installation check"→ page 23
• Checklist "Post-connection check"→ page 25

Programming procedure
Set-up of the decimal point (dP)
Press the
and
keys to select the decimal point position (from zero to 3 decimals). Press
confirm.
Default = 1 decimal
Set-up of the engineering value related to the zero point (ZErO)
Press the
and
keys to select the engineering value zero (-1999 to 9999). Press
Default = 0.0
Set-up of the engineering value related to the span range (SPAn)
Press the
and
keys to select the engineering range value (-1999 +9999). Press
Default = 100.0
Set-up of the limit on the input current (Li)
This parameter allows to select the over-load limit of the visualization.
If Li = 0, when the current overcomes the 20 mA value, the display will indicate the
sage
(
when the current is lower that 4 mA).
OL
-OL
If Li = 1, the visualization will be extended of a 10% over the 4...20 mA range, before indicating
the overload. In both cases, overcoming the display maximum readings (-1999 +9999), the over-
load message will be indicated.
Default = 1
Set-up of the filter (FiLt)
When the 4...20 mA is disturbed it is possible to select an higher value of FiLt in order to get a more
stable and clear visualization on the display.
Press the key to increase the filter value on the input and the key
It's possible to set-up different values from 1 to 8; when FiLt = 1 no filter is applied on the input and
the digital reading occurs every 250 ms.
In this case the updating period of the display will be 250 ms multiplied by the FiLt value.
Example: if FiLt = 5 the updating period of the display will be 1.25 s.
Default = 2
