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
Using the FUNCPROG tool these settings can be generated in table form for saving as a download text
file.
Passive Sensor Definition
Non factory default passive sensors with thermistor element of 10kΩ or greater may be configured
1. Set up a UI raft with suitable resistance links fitted and plug it in to the raft socket of the UI
being used. If the sensor was 20kΩ at 25°C then 20kΩ would be fitted in link 2 of the UI raft
2. Consult the manufacturers resistance chart for the sensor being used and connect resistance
equivalent to the reference values in Column 1 (note that in the reference column 1 the
reference value 150 is considered as 15°C once the decimal shift of -1 is applied at row 13)
3. Assign an otherwise unused Sensor Type to the test UI
4. In the Main I/O display read and record the raw count value, as displayed to the right of the
units for the UI to which the test resistance is connected
5. Enter the raw count in the table at the corresponding reference value row and column;
<row#><column#>=<raw count>
6. Complete the raw count entry for all reference points
7. If an intercept other than zero (0) is applied then raw count measurements must be at reference
values shifted an equivalent amount
Reset to Factory Default
The
FD=1
reset command also resets changes to the linearization tables
