When the input value fluctuates frequently, averaging can be used to produce
a stable input value, as shown in the following diagram.

The default setting is used to perform AD conversion of analog input values,
scaling them to a count between 0 and 6,000. Scaling can be used to change
scaled values that correspond to the input signal range into other values
required by the user (industry unit values). Scaling also eliminates the need
for ladder programming in the Master to perform math operations. The follow-
ing two methods of input scaling can be used.
Analog input values (count values) are converted to the original voltage and
current values. The units used are mV or
