Functions and
Operations
■ Extraction of square root operations
• A extraction of square root operations is available for each input to allow
direct input of the signal from a pressure differential flow meter.
• To use square root extraction, set "Square root extraction enable" to
"ON" (the initial setting is OFF).
• The square root extraction function includes the "Low-cut point"
setting such that when the result of the operation is below the low-
cut point, the result is set to "0". The low-cut point is set for each
input using normalized data such that the lower-limit of the input
setting range is 0.000 and the upper-limit is 1.000.
■ Other input adjustment functions
The following input adjustment functions are also available. These
functions are explained in "Section 8 Setting data" (P. 8-1).
• Line noise reduction: Input initial setting level
• Display digits after PV decimal point: Input initial setting level
