3. Average
You can set the average value between 1–100. It is a steady value obtained from the sum of the recorded
values. If the recorded values include an acute pulse due to unavoidable external factors, however, you
may observe violent changes in the average value. Use the filtering function to exclude acute pulses from
the sum-up and equalization, so that the computed average value is not affected by the acute recorded
values. Set the filter percentage to the range 0–3, where the unit is 10%. If you set the filter range to 0, the
system sums up all the recorded values and divides them to obtain the average value, but if you set the
filter range to 1, for example, the system excludes the bottom 10% and top 10% of the values and
averages only the remaining values to obtain the average value. For instantance, set the average value to
100 and set the filter percentage to 3. When there are 100 pieces of data collected, the system arranges
the collected data according to their values from large to small and then excludes the bottom 30% and top
30% of the values (60 pieces of data) and averages only the remaining values (40 pieces of data) to
obtain the average value.

4. Disconnection detection
Disconnection detection only operates when the analog range is 4–20 mA or 1–5 V. If a module that can
receive inputs between 4–20 mA or from 1–5 V is disconnected, the input signal exceeds the range of
allowable inputs, so the module produces an alarm or a warning.
