Signal Filtering / Averaging
You can adjust the filtering time constant to reduce the effect of noise or instability on your
input signal.
A larger FIL value will give a more stable display, but the response to signal changes will be
slower.
Because your output options, such as analogue output, alarm relays and serial output are all
derived from the displayed value, they will respond at the same rate as the filtered display.
This feature is available in Easy and Advanced Modes
