4.2.7 Signal Averaging - Setting Speed of Response
• The averaging can be used to smooth out the response to spikes or
unstable readings that may be caused by bubbles or small debris.
•
The response is done by averaging readings. Both displayed and output
values of NTU are affected in this menu. The default setting is 1; however,
up to 60 readings can be averaged.
• To avoid reading air and other anomalies, select a higher averaging.
• Select the lowest averaging where monitoring of rapid changes is needed.
These are one-second intervals so the maximum averaging is 60 seconds.
•
The factory default is 10.
To change the Averaging:
Enter the
CONFIG
mode by pressing the

and

buttons until the arrow beside CONFIG is illuminated, then press
the

