Optima HammerHead Electronics Instruction Manual

The Hammerhead, also has handsets called the primary and secondary, but each

has different purpose and functions. The primary is responsible for maintaining the

selected set-point, displaying the measured PO

for the three main oxygen sensors, time,

depth and decompression information. The secondary is a backup display for the main

oxygen sensors, and controller for the DIVA Heads-Up display. The secondary DOES

NOT CONTROL the solenoid, it is meant to allow the diver to manually maintain the

breathing loop in the event of a primary failure. The only common point between the

primary and secondary is the oxygen sensors. Each controller has an independent power

source.

SETUP and INSTALLATION

The Hammerhead allows for the tracking of sensor health by allowing the user to

display millivolt readings for each sensor. This is accomplished by utilizing the “MV

DISPLAY” option located under the “OPT” menu on both the primary and secondary

handsets once the harness is connected. Recording the millivolt readings for each cell

when exposed to air and oxygen will expose cells that are going non-linear. The actual

oxygen percentage used in calibration should also be recorded.
