When MLNB=TRIP leave piece linear compensation parameter loop
Set COMP
Parameter LED display Description Default Level
COMP Piece linear compensation compare value LSPL Fast
When non-linear signal value within the set value of COMP, it needs to be compensated.
First COMP set value=LSPL
First COMP set value=USPL
Set OFFS
Parameter LED display Description Default Level
OFFS Piece linear compensation offset value 0.0 Fast
When non-linear signal value within the set value of COMP, OFFS use for increase or decrease original non-linear signal

4. End compensation setting
setting SET9.1=1
Enable piece linear compensation
5. Function enable
setting MLNB = 1 setting OFFS = 0 setting COMP = LSPL
2. Basic parameter setting

1. Show parameter
Example1
Assume signal source is a nonlinear signal within 320 °C, and the controller is set to correct at three temperature points.
(1) When the temperature is 95°C, it needs to be corrected by +5°C.
(2) When the temperature is 185°C, it needs to be corrected by +15°C.
(3) When the temperature is 320°C, it needs to be corrected by +30°C.
Step 1: Set SET8.4=1 and SET9.1=0
Step 2: Set MLNB = 1, COMP = LSPL, OFFS = 0
Step 3: set MLNB = 2, COMP = 95, OFFS = 5
Step 4: Set MLNB = 3, COMP = 185, OFFS = 15
Step 5: Set MLNB = 4, COMP = 320, OFFS = 30
Step 6: Set MLNB = 5, COMP = USPL, OFFS = 0
Step 7: Set MLNB = TRIP and SET9.1=1
