4 Operations

Set-Up Alarms: Each of five alarms provided may be programmed to actuate at any O2 trace level above or below a threshold. The fifth alarm may also be programmed as a system alarm to monitor several system-level condi- tions. The system alarm can be triggered by the following system operations:

•Scheduled zero (AutoZero) failure

•Scheduled span (AutoSpan) failure

•Battery failure

•Internal errors

Any condition triggering the system alarm can be determined from status page 4 (see this chapter: System Statistics).

When the alarms are disabled, scheduled zeroing or spanning will not take place.

Logger Set-Up:A system data logger keeps a record of past oxygen measurements. The logger is presented in the form of a graphed chart on the system LCD; gaps in time will not display, and all points shown on a single chart have the same range and sensor number.

The logger will not record in the Test Alternate Sensor mode.

Set Up Clock Functions: An internal clock provides the time and date for events scheduled by the user. The internal clock is also used by the logger to record events scheduled at timed intervals.

Scheduled zeroing and spanning (AutoZeroing and AutoSpanning) are set in this mode. The mode uses an electronic timer to set off the zeroing or spanning sequence at pre-selected intervals. During an AutoZero or AutoSpan, the alarms are defeated and the screen displays “PLEASE WAIT. SCHED-

ULED SPAN IN PROGRESS.”

Since AutoZeroing and AutoSpanning uses automatic settling detection of the sensor, which can take up to fifteen minutes, oxygen monitoring will be interrupted for the length of time it takes to zero or span, after which monitor- ing will resume. The LCD will display the current background level during zeroing or spanning.

Changing Passwords For Remote Monitoring and Control:

Programmable security passwords are provided to prevent unauthorized access to remote monitoring and control. “Monitor” is the lowest authorization level and only permits monitoring of analyzer functions, while “Control” allows remote control of any function.

System Statistics: Menu screens are available to view various system parameters, and for setting serial link operation parameters, including modem operation.
