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

I nput analog value

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.
