The available functions for current (mA) output 1 are listed in the table below.
There are three fields to modify when setting up an output:
• Zero scale value: 0 or 4mA
• Full scale value: 20 or 22mA
•
Output function: + = forward (+) flow, - = reverse (-) flow, blank = absolute
flow, -0+ = zero flow center scale
The values corresponding to the scale points are shown in the following chart:

To change the setting, press enter to access the function. Use the right arrow
key to move the cursor and the up arrow key to change the value. Press enter to
accept changes and exit the function. Press escape to exit the program mode.
This function sets the full scale flow value for the analog output.
The maximum allowable flow rate is a function of the diameter of the flow sensor.
Regardless of the diameter, the maximum flow rate setting cannot exceed a
velocity of 10 m/s.
To change the setting, press enter to access the function. Use the right arrow
key to move the cursor and the up arrow key to change the value. Press enter to
accept changes and exit the function. Press escape to exit the program mode.
