Buttons
Data Entry Buttons: The < > arrow buttons select options from the
menu currently being displayed on the VFD screen. The selected option
blinks.
When the selected option includes a modifiable item, the
∆∆∆∆∆∇
arrow
buttons can be used to increment or decrement that modifiable item.
The Enter button is used to accept any new entries on the VFD screen.
The Escape button is used to abort any new entries on the VFD screen that
are not yet accepted by use of the Enter button.
Figure 4-1 shows the hierarchy of functions available to the operator via
the function buttons. The six function buttons on the analyzer are:
• Analyze. This is the normal operating mode. The analyzer
monitors the oxygen content of the sample, displays the
concentration of oxygen, and warns of any alarm conditions.
• System. The system function consists of six subfunctions that
regulate the internal operations of the analyzer:
• Auto-Cal setup
• Password assignment
• Self -Test initiation
• Checking software version
• Logging out.
• Zero . Used to set up a zero calibration.
• Span. Used to set up a span calibration.
• Alarms. Used to set the alarm setpoints and determine whether
each alarm will be active or defeated, HI or LO acting, latching,
and/or failsafe.
• Range. Used to set up three analysis ranges that can be switched
automatically with autoranging or used as individual fixed
ranges.
Any function can be selected at any time by pressing the appropriate
button (unless password restrictions apply). The order as presented in this
manual is appropriate for an initial setup.
