Item# Parameter
Name
Parameter description
0 TIME CONSTANT 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)
1 FAST RESPONSE
FILTER ENTRY
(Chrontrol) When the difference between the current gauge reading and the previous gauge
reading exceeds the value of this entry, temporarily bypasses the filter
2 SPAN Application of gain to get normalized counts after subtraction of cal low
reference. Gain=entry/1000
3 LINEARIZER
NUMBER 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.
4 TEMPERATURE
COEFFICIENT When temperature compensation enables. Entry=0.0XXXXXSGU per
degrees C or F
5 DENSITY TYPE 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
6
SOLIDS DENSITY For density types 1 and 2 only
7 LIQUID DENSITY For density types 1 and 2 only
