Active Sensor Scalings
Column 1 is the fixed reference to which all display results are based. The range of the reference
column 1 is effectively 0…1000.
It is important to interpret the reference values in combination with the intercept and scaling data at
rows 12…14. Taking Sensor Type 2, 0-10Vdc, as an example:
The microprocessor raw count range of 0…1000 relating to 0-10Vdc results in 0…100% display
because the reference column values are being decimal shifted one place to the left (row 13
column 4 = -1
If 0-10Vdc is to be displayed directly as 0-10Vdc then we need to decimal shift -2 at row 13
column 4 and change Units display characters
o
134=-2
o
14=V (row 1 column 4)
o
24=d (row 2 column 4)
o
34=c
(row 3 column 4)
If 0-10Vdc is to be displayed as 0…50°C then decimal shift the display reference range -2 at
row 13 column 4, multiply it by 5 at row 14 column 4 and change units characters (remove
surplus characters by entering a <space>)
134=-2
144=5
14=C
(row 1 column 4)
24=<space>
(row 2 column 4)
34=<space>
(row 3 column 4)
If a second 0-10Vdc sensor with different scaling is needed, say, 0…2000 PPM, then copy
default 0-10Vdc raw count data to a column who’s existing sensor data will not be used in
future. The following settings assume overwrite of the Ni1000 column 3 (Sensor Type 1)
13=P
23=P
33=M
43=0
53=150
63=300
73=450
83=600
93=750
103=900
113=1007
123=0
133=0
143=2
In the last example the display reference column range is unchanged, 0…1000, until the multiplier at
row 14 is applied (x2) resulting in a final scale for PPM of 0…2000.
Note: The value at the intercept row, 12, will have the decimal shift (row 13) and multiplier (row 14)
applied to it. Therefore, if intercept -10.0 is required and decimal shift will be -1 (x0.1) then enter -100 in
row 12 as the final result after processing with the decimal shift will be an intercept of -10.0
