Features
•
Simple self intuitive two button menu and confirm system.
•
Independent isolated display system with pressure/gas resistant cabling.
•
Independent pressure/water proofed primary and secondary electronics and
power supplies.
•
Jaksa power efficient automatic oxygen addition system. (Operational time
is dependant on diver’s use of backlight, ambient temperature, battery
make, age of battery, and diver use.). Using the Alkaline AA battery packs,
experience varies with the Primary, usually 25-50 hours, then for the
secondary subsystem at 50-100 operational hours.
•
Average PO2 window. (
Bold annotation on display
)
•
Tertiary redundant oxygen sensor system
•
3 sensor independent window.
•
Voting logic automatic oxygen addition system.
•
Voting logic indicator. Indicates what specific sensor is out of tolerance at
that moment. (A sensor that may become disconnected or completely fail,
the APECS™ will still average and maintain the current set point.)
•
Current set point window.
•
Breathing loop temp. (Monitors breathing loop temp that the diver is
breathing)
•
Ambient water temp.
•
Set points selectable on the fly: Manual mode (0.20), 0.5, 0.7, 1.0, 1.1, 1.2,
1.3, 1.4, and ASP.
•
Bilinear 2 point calibration system. (For accurate high and low point PO2
information).
•
High Altitude Oxygen Sensor Calibration (Both Metric [meters] and Imperial
[feet] altitudes).
•
Sensor MV indicator. (Gives sensor output (Millivolts) on the fly to the diver
in real time. This will indicate to the diver the health of the sensors and
voting logic validation).
•
Low battery indicators.
LOW BATT
annotation will appear blinking at 5.2
volts, with the auto disabling of the display backlight further indicating to the
diver a low power situation for the primary electronics system.
•
BATTERY
no-load/load indicator. (Indicates to the diver the health of the
power supply while under a load from the solenoid)
•
BACK LIGHT
enable/disable option.
•
KEEP BACK LITE ON
enable/disable option
•
DISPLAY POWER
option enable/disable option
•
System status: It is the heart beat indicating to the diver that the electronics
have not locked up and are functioning.
