partial pressures of oxygen (PO2). There are a maximum of nine

you descend due to higher partial pressures and may decrease

when you ascend.

(5) Dive time: This is the time spent (in minutes and seconds)

(6) Remaining no-decompression limit (NDL): This is the time

that is remaining (in minutes) before you reach the no-

decompression limit. This NDL time limit increases when you

ascend and decreases when you descend.

(7) Mix number: This is the mix number for which the

computer is currently calculating dive data.

(8) O2 and HE percentages: This is the oxygen and helium

percentages programmed for the gas mix number that is selected.

(9) PGT bar graph: This is how much nitrogen and helium the

means that you are at or have exceeded the no-decompression

limits.
