© Pelagic, 2019 Doc. No. 12-79 3 9 -r01 (11/12/19 )
AMPHOS AIR 2.0 BATTERY STATUS , information includes (Fig. 34):
> Graphics bAtt and AMPH (meaning AMPHOS AIR 2.0).
> Graphic Good or Lo.
> Battery icon, if a Low Battery warning condition exists, flashing if an alarm condition exists.
TRANSMITTER (TRT) STATUS , information includes (Fig. 35):
> Graphics bATT and Good (or Lo) with Tank 1 (or 2) icon.
> Tank Pressure with PSI (or BAR) icon.
- - or - -
> Graphics Not AVAIL, and TRT1 (or 2) with Tank 1 (or 2) icon, if that TRT is not in use or not reporting.
NORM/GAUG SET MODES
Sequence >> SURF Main > Set F (FO2) > Set A (Alarms) > Set U (Utilities) > SN (Serial Number).
> Access and step through of the sequence is gained by simultaneous 2 second presses of A and S.
> Alarms and Utilities can also be set/changed using the PC Interface program. FO2 must be set using the push buttons.
> Settings remain at the values saved until they are changed.
SETTING FO2 FOR NITROX DIVES
For each value of FO2, the MOD (Max Operating Depth) that can be achieved for the PO2 Alarm value set will be displayed.
When the FO2 50% Default is set On and FO2 Gas 1 is set for a numerical value, 10 minutes on the surface after that dive, FO2 for Gas 1
will be displayed as 50 and further dives will be calculated based on 50% O2 for oxygen calculations and 21% O2 for Nitrogen calculations
(79% Nitrogen), unless the FO2 for Gas 1 is set before the dive.
FO2 for Gas 1 continues to reset to the FO2 50% Default after subsequent repetitive dives until 24 hours elapse after the last dive, or the FO2
50% Default is turned Off.
When the FO2 50% Default is set Off, the FO2 for Gas 1 will remain at the last value saved for the remainder of that series of repetitive dives.
FO2 SET FOR AIR
The default FO2 for Gas 1 each new dive period is AIR.
When FO2 for Gas 1 is set for AIR, calculations are the same as when it is set for 21%. When FO2 for Gas 1 is set to AIR, it remains set for
AIR until it is set for a numerical FO2 value (21 to 50%).
When FO2 is set only to AIR, the O2BG and PO2 values and/or warnings will not be displayed during the dive.
MODs affected by the PO2 limit set will not be displayed when FO2 for Gas 1 is set to AIR.
Internally, the AMPHOS AIR 2.0 keeps track of the O2 so that if FO2 for Gas 1 is subsequently set for a numerical value, the O2 accumulated
during previous AIR dives will be accounted for in the next Nitrox dive (during that dive period and series of repetitive dives).
Once FO2 Gas 1 is set for a numerical value (21 to 50%) and a dive is made, the AIR option is disabled until 24 hours elapse after the last
dive. The AIR option will not be displayed in Set FO2 Gas 1 until a full 24 hour Surface Interval has elapsed.
If FO2 for Gas 1 is set for 21%, it will remain set for 21% for that series of dives until set for a higher numerical value.
If the FO2 50% Default is set Off, FO2 for Gas 2 will remain as previously set until it is changed. If the FO2 50% Default is set On, FO2 for
Gas 2 will Default to 50% after the dive.
SET F GROUP (FO2)
Selections >> Gas 1 > Gas 2 > 50% Default.
> A + S (2 sec), while viewing NORM SURF Main, will access Set F (Fig. 36).
> A (< 2 sec) will then access Set FO2 Gas 1.
SET GAS 1 (FO2 & PO2 Alarm), information includes (Fig. 37):
> Graphic Air flashing, or -
. . Max Depth allowed with MAX and FT (or M) icons.
. . PO2 Alarm value with PO2 icon.
. . FO2 (numeric) value flashing.
. . Nx icon.
> Gas (tank) 1 icon.
> Graphic GAS1.
• S (hold) to scroll upward through FO2 settings from Air to 21 through 50% in 1% increments at 8/sec, stopping when the button is
released, or at 32, then at 50 (even if S is held depressed), then stop at Air (or 21 if a repetitive Nitrox dive).
• S (< 2 sec) to step upward through the Set Points one at a time.
• A + S (2 sec) to save the setting and revert to Set F.
• A (< 2 sec) to save the setting and flash the PO2 digits if Nitrox, or access Set Gas 2 if Air.
To set PO2, if flashing -
• S (< 2 sec) to step upward through the Set Points of 1.00 to 1.60 one at a time in increments of 0.10.
