Value on over-range
Set how to detect over-range values on linearly scaled or square-rooted I/O channels.
In either case, +over range occurs if the value excluding the decimal point exceeds 99999
and –over range if it falls below –999999.
Options Description
Free The value is set to –over range if the value is less than –5% of the measurable
span range and +over range if the value is greater than 105%.
Over The value is set to –over range if the value is less than –5% of the span setting
(Linear scaling or , Square root span) and +over range if the value is greater
than 105%.
Example: If the linear scaling scale is 0.0 to 200.0, a value less than –10.0
results in a –over range, and a value greater than 210.0 results in a +over
range.
