7 Analog Conditioning
7.1 Filter
Filter Constant sets the level of digital filtering according to the following chart.
Digital Filtering. The illustration above demonstrates the effect of digital filtering
(set with Filter Constant) on module response to a
temperature change.
It is recommended that the filter constant for the HE-XE103-10 be set to a value
of 7. This will minimize noise and jitter, improve effective resolution, and provide
adequate speed for most temperature monitor and control applications.
7.2 Sensor Linearization
7.2.1
ES2T-250/300 Channel 1
Linearization must be performed by the user in the ladder application code, using
26 internal %R registers per channel. The example below uses %R1-26 to
linearize one channel - %AI1. Linearization consists of the following example
steps.
1) 1) Load the desired linearization coefficients into a table on first scan
using a Move Constant Data block.
Registers (Real) Degrees F
R0011 -1.56518643899245e-27
R0013 +1.85504500007145e-22
R0015 -8.93939520118636e-18

R0023 -1.08497438404356e-01
R0025 +3.42114564669736e+02
2) Load %AI0001 into %R0001 as a Real.
3) Perform the Real Math Expression
4) %R3 = (((%R11*%R1+%R13)*%R1+%R15)*%R1+%R17)
5)
Perform the Real Math Expression %R5 =
(((%R3*%R1+%R19)*%R1+%R21)*%R1+%R23)*%R1+%R25
6) Load %R0005 result into another register such as %R0007 to save
the temperature value.
7) Steps 2 though 5 can be on a single rung.
7.2.2 ESP-100 Channel 2
Linearization must be performed by the user in the ladder application code, using
26 internal %R registers per channel. The example below uses %R31-57 to
linearize one channel - %AI2. Linearization consists of the following example
steps.
1) Load the desired linearization coefficients into a table on first scan using
a Move Constant Data block.

2) Load %AI0002 into %R00051 as a Real.
3) Perform the Real Math Expression
4) %R53 = (((%R31*%R51+%R33)*%R51+%R35)*%R51+%R37)
5) Perform the Real Math Expression %R55 =
(((%R53*%R51+%R39)*%R51+%R41)*%R51+%R43)*%R51+%R45
6) Load %R00055 result into another register such as %R00057 to save the temperature
value.
7) Steps 2 though 5 can be on a single rung.

WARNING: To avoid the risk of electric shock or burns, always connect the safety (or
earth) ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as
close to the source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against
risk of fire and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a
repeated failure indicates a defective condition that will not clear by replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction and
operation of this equipment and the hazards involved should install, adjust, operate, or
service this equipment. Read and understand this manual and other applicable
manuals in their entirety before proceeding. Failure to observe this precaution could
result in severe bodily injury or loss of life.
Warning: Consult
user documentation.
Warning: Electrical
