Parameter description
When the product code table entry #18 is set to zero, time constant is the time (in
XXXXX seconds) that 63% of a step change applied at the input of the digital
filter will appear out the output of the filter
When the product code table entry #18 is set to one, time constant defines the
number of readings to use to generate a measurement average. (100 readings
max)
When the difference between the current gauge reading and the previous gauge
reading exceeds the value of this entry, temporarily bypasses the filter
Application of gain to get normalized counts after subtraction of cal low
reference. Gain=entry/1000
Which linearizer curve to use (0–9). Normally, the curve number is the same as
the product code number. For example, Product Code #0 usually uses Curve #0,
Product Code #1 uses Curve #1, etc.
When temperature compensation enables. Entry=0.0XXXXXSGU per
degrees C or F
Enter 0=channel is not density or is straight density in SGU units. Enter
1=channel is a slurry gauge and converts to %Solids and Dry Solids. Enter
2=solutions and gives %Solids conversion
