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 or the Pilot Module, you prefer to supply analog
set point signal to the Smart-Trak 2, 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.
CAUTION: If you change the source of the setpoint to one of the analog
values, you will not be able to control your Smart-Trak 2 with your computer.
