Setting parameters
If parameter mode is not released within 30 s of calling up a parameter
setting function, the instrument returns to monitoring and display mode.
Press either of the set keys (
or
) to exit parameter mode while
setting parameters (prior to concluding the session by depressing the enter
key
).
The instrument will return to monitoring and display mode if no parameters
are entered within 30 s of entering parameter mode.
The original parameters will not be affected in either of these cases.
While in parameter mode, the instrument will continue to monitor pressure and
control the switching outputs and analogue outputs.
WARNING!
Hysteresis is critical for all switching values (see fig. 5) in order to
prevent the relay from “fluttering” or the transistors from periodically switching
on/off.
