Alarm Valid- This value is set to a default of 0 seconds. This is the amount of time an alarm
condition must be present for an actual alarm to occur. In certain processes with rapidly
changing conditions, this value can be changed to prevent undesired false alarms. Press the
SELECT/PROG with Alarm Valid selected. Use the RIGHT ARROW button on the keypad
until you get to the digit that you want to change. Use the DOWN ARROW/UP ARROW
buttons on the keypad to change the values. To change a digit from a numerical value to zero,
change the value to a zero. When the correct value has been selected, press the
SELECT/PROG button and the value will be confirmed. To escape from this menu without
changing the value, press the BACK button and the main channel menu will appear.
Comm Port- Indicates data output function. There are several settings but the only active
settings are Off and Serial Report (Sio Report). If Off is selected, no data for the selected
channel is sent out the Serial Port. If Sio Report is selected, data is sent out the Serial RS232
port at the frequency programmed in the Global Settings Menu. Reports are not required to be
automatically generated with the PressureMAT Data Acquisition Software (see Appendix C for
details on data collection from the PressureMAT). Press the SELECT/PROG with Comm Port
selected. Use the DOWN ARROW/UP ARROW buttons on the keypad to change the settings.
When the correct setting has been selected, press the SELECT/PROG button and the value will
be confirmed. To escape from this menu without changing the value, press the BACK button
and the main channel menu will appear.
