【Table 3】 How to use No-decompression Dive Limit - Residual Nitrogen Time Table? |
You can examine No-decompression Dive Limit and Residual Nitrogen Time after Surface Interval Time in【Table 3】No-decompression Dive Limit - Residual Nitrogen Time Table. |
You can examine the No-decompression Dive Limit for the second diving
|
 |
A diver of Residual Group E at the time of the first diving end plans the second diving of 15 m after 1 hour 30 minutes Surface Interval Time.What is the new no-decompression dive time? |
|
《The usage of Dive Table》
① Residual Group at the time of the first diving end is E in【Table 2】Surface Interval Time Table.
② You just trace aside from E and look for Surface Interval Time that is 1 hour 30 minutes or over 1 hour 30 minutes and closer to 1 hour 30 minutes.1 hour 30 minutes is between 1 hour and 2 hours.You just trace the line between 1 hour and 2 hours below.
③ You can look for the contact of the point traced 15 m aside and the point traced the ② line in 【Table 3】No-decompression Dive Limit - Residual Nitrogen Time Table. |

Correct answer: 51 minutes
A number of the top right corner is the new No-decompression Dive Limit at the contact.
A diver of Residual Group E at the time of the first diving end can plans the second diving of 51 minutes at 15 m after 1 hour 30 minutes Surface Interval Time. |
