Clearing (Resetting) Alarms
Active alarms can be cleared (reset) from the Stat\History menu. Clearing the
alarms removes any active alarms from the User Interface display and stores
them (up to a maximum of nine) in the History Buer (^SC or ^XSC), also in
the Stat\History menu. A password is not required to perform this command.
To clear alarms:
1. From the RUN menu, press to view the Stat\History menu. The rst
menu item you will see is the “En\Dis Alrm?” prompt.
2. Press once to view the “Clear Alarm?” prompt. While this prompt is on
the User Interface, press the ‘+’ button to clear the alarms; the message
“Cleared” will appear on the User Interface.
If you do not wish to clear the alarms, press the ‘–’ button; the message
“NotCleared” will appear on the screen. Or, you can press to scroll past
the “Clear Alarm?” prompt and leave the alarms in their current state.
Enabling/Disabling the O-Spec Alarm
The O-Spec Alarm can be enabled (turned on) or disabled (turned o) from
the Stat\History menu. When the O-Spec Alarm is enabled, LED 1 is O;
when the O-Spec Alarm is disabled, LED 1 is On to alert the operator to this
condition. A password is not required to perform this command.
To enable or disable the O-Spec Alarm:
1. From the RUN menu, press to view the Stat\History menu. The rst
sub-menu item you will see is the “En\Dis Alrm?” prompt.
2. If the O-Spec Alarm is already in the current state you require, press to
scroll past the “En\Dis Alrm?” prompt and leave this parameter in its cur-
rent state.
To enable the O-Spec Alarm if it is currently disabled, press the ‘+’ button.
LED 1 will turn O to indicate the O-Spec Alarm is enabled.
To disable the O-Spec Alarm if it is currently enabled, press the ‘–’ button.
LED 1 will turn On to indicate the O-Spec Alarm is disabled.
