The PO

warning will occur at the value you set for it while in Dive Set mode.

Figure 16 PO

warning.

 If you set the PO

warning for 1.4 atmospheres, an alarm will sound and the cur-

rent depth and PO

information will blink on and off.

 If you set the PO

warning for 1.6 atmospheres, the OLI graph will blink as well.

Oxygen Limit Index (OLI) The NiTek He’s Oxygen Limit Index (OLI) reects the

cumulative effect of your exposure to elevated partial pressures of oxygen. Where

as the PO

Warning accounts only for the intensity of such exposure, the OLI

accounts for both its intensity and length.

Figure 17 OLI warning.
