3.3 Analyser setup (Refer to Figures 3a and 3b)
The setup function allows the user to modify and view the
analyser configuration (outputs, alarms, blowback, clock and
passwords).
3.3.1 Setting up the concentration alarms
The control unit has 2 concentration alarms that can be
assigned to either of the 2 possible sensors in the sensor head.
Each concentration has a user configurable level, hysteresis
and polarity (high or low alarm).
Each alarm may also be configured to either freeze (remain
fixed at the last value) or follow (track the concentration
changes) during analyser calibration.
The setup process is as follows:
1. Press the MENU key, then select CONFIGURE, enter a
valid password, select SETUP and then ASSIGN.
2. Select ALARMS to set up the concentration alarms.
3. Select AL1 or AL2 to specify which alarm is to be set up.
4. Select either NONE, OXYGEN or COe to disable the alarm
or to specify the measurement to be the subject of the
alarm.
5. Select either FREEZE or FOLLOW to specify if the alarm is
to be fixed at its current value or to track the concentration
during analyser calibration.
6. Select either LOW or HIGH to specify the alarm as a low
alarm or a high alarm.
7. Use the arrow keys followed by the ENTER key to set the
concentration level at which the alarm is to be triggered.
8. Use the arrow keys followed by the ENTER key to set the
hysteresis on the alarm level.
The alarm assignment is now complete and the user is returned
to the select alarms display (step 3 above) to allow other alarms
to be configured. Use the QUIT or MEASURE key to return to
the assign menu or the measure display as required.
