3.2.6 Setup of the filter (FiLT)
When there is interference with the 4...20 mA signal, it is possible to set a higher filter value
"FiLt" in order to obtain a more stable and accurate display.
• Press the key to increase the filter value and the key to decrease the filter value.
• Filter values ranging from 1 to 8 can be set where "FiLt = 1" represents a switched off filter
and the display value is updated in this case every 250 ms.
• If "FiLt > 1", the update time of 250 ms is multiplied by the respective set filter value. If, for
example, "FiLt = 5" the display value is updated every 1.25 s.
3.2.7 Setup of the resolution (riS)
This function is used to set the resolution of the display. Adjustable values for "riS" are: 1, 2, 5
and 10
• When "riS = 1" all possible digits within the programmed measuring range are shown
continuously.
• When "riS = 2", the steps of two consecutive values are doubled, i.e. odd values can then no
longer be displayed (0, 2, 4, 6, 8,…).
3.2.8 Summary
INFORMATION!
The factory default setting is "FiLt = 2".
INFORMATION!
It is recommended that the resolution only be reduced when the measuring range is extremely
large, e.g. 10000 points or when the 4...20 mA signal is very unstable. If that is not the case, the
maximum resolution is always set: "riS = 1". That corresponds to the factory default setting.
