Linearization

Define the range for the analog input, and modify the weighting of the analog input
using a 16-digit (maximum) breakpoint table. When used properly, this point can
provide some helpful insight into setting FlowShark Pulse parameters. For example,
the user can convert a depth/height signal into a volume-proportional signal, which
can be saved, or route the signal to one of the analog outputs for further processing or
display.

Simply enter the number of breakpoints, and then confirm the entry by pressing

.

This displays a table with the respective units.

Figure 8-42 Table of values for analog input range

Enter the mA value in the X-column and the other value in the Y-column (The user
previously selected the appropriate unit of measure through the Units menu option).

For standard (linear) applications, such as setpoint input, or to save a reading, enter 2
as the breakpoint value. Then, define the analog input range (i.e., enter the respective
values for 4 mA and 20 mA).

Offset

In addition to the input current, add a fixed positive or negative offset to the analog
value using the units previously chosen.
