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

screen. The
Escape

Figure 4-1 shows the hierarchy of functions available to the
operator via the function buttons. The six function buttons on the
analyzer are:
•

monitors the oxygen content of the sample, displays the
percent of oxygen, and warns of any alarm conditions.

that regulate the internal operations of the analyzer:
•
Track or hold values during calibration
