Error, Over, Channel Limit Value | Omega RD100B instruction

9.17 Setting the Procedure Taken When the Computed Result Is in Error

Explanation

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	Limit 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 2V range)
	+Over: The maximum measurable value at the specified range type
	(Example: 2.000 at 2V range)

Computation channel	–Over: –100000000, +Over: 100000000 (excluding the decimal)
