Error
Specifies how to display or print the computed result when computation errors occur.
+Over: Set to +over. Displayed/Printed as “+Over.”
–Over: Set to –over. Displayed/Printed as “–Over.”
Computation that result in errors
• x/0
• SQR(-x)
• LOG(-x)
• When a channel set to Skip is included in the equation
Over
Selects the procedure when an “over” value * is input for TLOG.SUM or TLOG.AVE
computation.
* An “over” value on a measurement channel refers to +Over or –Over. See section 12.4. An
“over” value on a computation channel refers to a value that is less than or equal to
–100000000 or greater than or equal to 100000000 excluding the decimal.
Skip: The “over” value is not used in the computation.
Limit: The following limit value is used for the computation.
Channel Lmt Value
Measurement channel • For scaling (1-5V, scaling, and square root)
–Over: –315000, +Over: 31500 (excluding the decimal)
• For input types other than scaling
–Over: The minimum measurable value at the specified range type
(Example: –2.000 at 2 V range)
+Over: The maximum measurable value at the specified range type
(Example: 2.000 at 2 V range)
Computation channel –Over: –100000000, +Over: 100000000 (excluding the decimal)
