This screen provides the user with a way to command the DeltaFlow to enter various modes, perform
QA checks, or open individual valves. The top of the screen shows the current mode of the DeltaFlow.
Next to each button is an indicator that will turn GREEN to show the valve or mode is active. When
activating some of the valves (SVx), other valves may automatically activate to avoid damaging the
instrument. Clicking any of the buttons in the “Valves” section will automatically put the DeltaFlow in
Maintenance mode until you manually put it back in service by clicking the Maintenance button. When
initiating a calibration or interference check, the DeltaFlow will wait for the top of the minute before
starting. This is indicated by the button blinking and the message at the top of the screen. Below is a
short description of each button’s functionality.
