Example:
If the gain is 1000 and the offset is 0, the corresponding value for the original signal 0° C to 100° C is 0–1000.
If you change the offset to 100, the calibrated value for the original signal 0° C to 100° C becomes 100–1100.
Gain = 1000, Offset = 0

4. 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 the acute pulses from the
sum-up and equalization, so the computed average value is not affected by the acute recorded values. Set the
filter percentage to the range of 0–3, where the unit is 10%. If you set the filter range to 0, for example, 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, the system excludes the bottom 10% and the top 10% of the values and averages only the
remaining values to obtain the average value.

5. Disconnection Detection
If the channel is open, the module can detect when it is disconnected. If the input is open-circuited, the
module produces an alarm or a warning.
