Math Constants (
Const
)
The
Math Constants
menu is used to set the constants used in channel
C math. The math functions include adder constant P, and factor
constant F.
The
Adder
constant (P) may be set from -99.999 to 999.999.
The
Factor
constant (F) may be set from 0.001 to 999.999.
The chart on page 79 details the math functions that may be selected in
the
Math Function
menu.
Low-Flow Cutoff (
CutofF
)
The low-flow cutoff feature allows the meter to be programmed so that
the often-unsteady output from a differential pressure transmitter, at low
flow rates, always displays zero on the meter. The low-flow cutoff for
each channel is programmed independently.
The cutoff value may be programmed from 0 to 999999. The meter will
display zero below the cutoff value. Programming the cutoff value to
zero disables the cutoff feature.
