4.2.5.1.2. Range

A Fixed Range Constant that refers to the three user-selectable ranges of

proportional current; 0 to 20mA, 4 to 20mA and –20 to +20mA.

4.2.5.1.3. Min / Max Value

Min / Max Value are Variable Range Constants used to define the

endpoints in the operating window of the output current. The Min Value

Max Value defines the Input source value that will produce the m

current. For example, if the selected range is 0 to 20 mA , a Min Value

1 kHz will produce 0 mA and a Max Value of 2 kHz will produce 20

mA. Since the output is proportional to the input and response is linear, it

is easy to calculate expected values within the defined value limits.

Therefore an input value of 1.5 kHz is at 50% scale and will yield 10mA.
