Set-Point Operation

One of the main features of the hammerhead is the ability for the diver to select a

new set-point based on a user programmed set of five choices. The hammerhead comes

pre-programmed with set-points of 0.4, 0.7, 1.0, 1.2, and 1.4. Regardless of the current

operating set-point pressing the left button will cycle through the set-point choices in

sequence. Once the desired set-point is displayed it is selected by pressing the right

button.

The secondary handset displays system status, warnings and PO

on a single

screen. Any PO

changes on the primary should be also performed on the secondary. All

warnings and alarms are based on the deviation from the selected set-point.The set-point

is selected in the same manor as the primary, pressing the left button to cylce through the

choices and the right button to select the displayed set-point.

The top line of the

display shows system

status (<OK>,

<WARN>, ALERT, or

PO2! ERROR!). This is

followed by the

calculated average PO

and the selected set-

point. The second line

displays the PO
