When the operation ch=0, since the reference value=0 at start-time,
high/low limit judgments are made with:
High Limit=100
Low Limit=50
When the operation ch=1, since the hold=75 on ch=0,
high/low limit judgments are made with:
High Limit=100 + 75 = 175
Low Limit= 50 + 75 = 125
When the operation ch=2 , since the hold=150 on ch=1,
high/low limit judgments are made with:
High Limit=100 + 150 = 250
Low Limit=50 + 150 = 200
When the operation ch=3 , since the hold=75 on ch=2,
high/low limit judgments are made with:
High Limit=100 + 75 = 175
Low Limit=50 + 75 = 125
Example of use of High-Low Relative:
When the High Limit Setting=100, and the Low Limit Setting=50
