Select Menu (
SElEct
)
The
Select
menu is used to select the signal input conditioning applied to the input (linear, square root, or
programmable exponent, low-flow cutoff, and analog output programming. The multi-point linearization is
part of the linear function selection.
Signal Conditioning Selection (
Functn
)
The
Function
menu is used to select the number of points used in the linear conditioning function applied
to the input.
Controllers are set up at the factory for linear function with 2-point linearization.
Multi-Point Linearization (
Linear
)
Controllers are set up at the factory for linear function with 2-point linearization. Up to 32 linearization
points can be selected under the linear function.
The multi-point linearization can be used to linearize the
display for non-linear signals such as those from level transmitters used to measure volume in odd-
shaped tanks or to convert level to flow using weirs and flumes with complex exponent.
Low-Flow Cutoff (
CutofF
)
The low-flow cutoff feature allows the controller to be programmed so that the often-unsteady output from
a differential pressure transmitter, at low flow rates, always displays zero on the controller.
The cutoff value may be programmed from 0 to 999999. The controller will display zero below the cutoff
value. Programming the cutoff value to zero disables the cutoff feature.
Total and Grand Total Count Direction (
Count
)
By default, the batch total and grand total count up during batch processes.
Count
parameter allows this
to change. When set to count down, the batch total will count down from the preset to 0. W hen set to
count down, the grand total will count down from a set value to zero.
