4.7 Lower Section of Software Window-Changing Parameters
Across the bottom half of the screen you will find a number of white boxes. Each box allows you to adjust one or
more meter functions. The various functions are reviewed in the following section.
Change Setpoint Value (flow controllers only)
This is the box that allows you to change the setpoint of the mass flow controller. To make a change to the setpoint
value, move your pointer to this box and left click. You may change a digit or delete the current setpoint and key
in a new one. When you have made your selection, press the enter key to implement it.
If, instead of using the RS-232 link, you prefer to supply analog set point signal to the SmartTrak, activate the pull-
down menu. Make your selection carefully and click. Your selection will appear in the box and, after a few seconds,
it will also appear in the yellow setpoint box.
WARNING: If you change the source of the setpoint to one of the analog values, you will not be able to
control your SmartTrak with your computer.
