Figure 7-2. Screen Flow Diagrams For Hold
State of Operation.
As seen by Figure 7-1, an active Hold
condition can be completely removed or
manually altered. If a Hold condition is not
active, the option to Hold All (i.e., HLD.ALL)
is given. In the latter case, confirmation
of this action using the YES Key causes the
TB84PH Advantage Series analyzer to hold all
analog and relay outputs at the levels and
states captured when confirmation is made.
If a Hold All or Release Hold action in not
confirmed by using the NO Key, each output can
be independently held to the capture
level/state or to a manually set level/state.
Figure 7-3 and 7-4 show the programming
prompts, smart key assignments, and resulting
actions.
