6. Set the Switch Read to Manual or Automatic .
Pressure switches are electro-mechanical devices that change their output
state (on or off) at a prescribed pressure value. These states are usually
associated with the opening and closing of an electrical circuit as a result
of the change in pressure. The open or closed state of the electrical circuit
can be read with a continuity checker. The Handheld Control has a built in
continuity check function that communicates with the Controller. If Switch
Read is set to Automatic, the Handheld automatically measures the
pressure that the pressure switch changed its state. If the Switch Read is set
to Manual, the user pushes
the pressure switch changed its state.
