Signal Conditioning Selection (
Functn
)
The
Function
menu is used to select the signal conditioning function applied to the input: linear, square
root, or programmable exponent. The multi-point linearization is part of the linear function selection.
Controllers are set up at the factory for linear function with 2-point linearization. The linear function
provides a display that is linear with respect to the input signal.
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. When set to
count down, the grand total will count down from a set value to zero.
Programmable Function Keys User Menu (
user
)
Changing the programming of the F1-F3 function keys will disable
the default batch operation of these keys, and is not recommended
for batch control applications.
The
User
menu allows the user to assign the front panel function keys F1, F2, and F3, the digital input F4
(a digital input located on the signal input connector), and up to eight additional digital inputs to access
most of the menus or to activate certain functions immediately (e.g. reset max & min, hold relay states,
etc.). This allows the meter to be greatly customized for use in specialized applications.
Up to eight digital outputs can be assigned to a number of actions and functions executed by the meter
(i.e. alarms, relay acknowledgement, reset max, min, or max & min, tare, and reset tare). The digital
outputs can be used to trigger external alarms or lights to indicate these specific events.
