Setting the Tolerance Setting Value
The tolerance setting value consists of the upper limit value (HIGH side setting value) and 
the lower limit value (LOW side setting value). By setting these values, judgments are made 
in three levels: when the judgment value (P.V.) goes beyond the upper limit (HIGH 
judgment), when the judgment goes beyond the lower limit (LOW judgment) and when the 
judgment is within the acceptable range (GO judgment). Then, the judgment indicator and 
judgment output are turned ON/OFF.
*1 When the output state of judgment output is Normally Open (default value) ON/OFF is
reversed for Normal Close.
"5. Output State" (page 4-14)
*2 The judgment indicator ON/OFF condition can be changed.
"18. Display Color" (page 4-41)
*3 "Error Displays and Corrective Actions" (page A-4)
The tolerance setting value can be set either manually or automatically.
