• Computation Error
Set whether to apply an the computed value to the upper limit value (over) or the
lower limit value (under) if the computed results in an error.
Over:
105% of the value is output for an overrange.
Under: –5% of the value is output for an underrange.
Note
• The following values are output when the computed result is overrange or underrange.
Overrange: 105%
Underrange: –5%
• The following are causes of computation errors.
• Error in computation (divide by 0 etc. )
• The equation is used, and a burnout occurs on channels whose burnout is set to ON
• Trouble occurred with the AD converter on channels using the equation
• Channels using the equation are set to Skip.
