AVERAGE
Average: The sensor will average the number of samples set in the Average
Parameter. Each qualified sample is placed into a buffer and averaged with the
previous samples to generate a steady output. A qualified sample is one that falls
within the boundaries set in the Out of Range Span Parameter.
To Read the number of samples being averaged in a sensor, use the command
structure:
Send Receive

00h Data (not used) ##h Average (High Byte)
00h Data (not used) ##h NA (Low Byte)
55h End Byte ##h NA
