SAC Rate - OceanLog 2.2.0

[txmanager]

I just bought a DataMask a couple weeks ago and installed the OceanLog program. I am brand new to this program. I see there is place your SAC rate should be displayed but on the 3 dives I have logged, it gives me 0.0. Is there something I need to do to activate that calculation?

The SAC calculation has been an ongoing issue in OceanLog.

I am pretty sure 2.2.0 has addressed the SAC issues that were in 2.1.8.

You need to make sure that the following fields are filled in:

Start Pressure (Start)
Working Pressure (Work)
Cylinder Size (Size)
Dive Time (Time)
End Pressure (End)
Average Depth (Depth)

With any one of those fields missing, it will not calculate.

Here is the formula if you are trying to manually check, I put the variables in parenthesis next to the Oceanlog descriptions above.

SAC=(((Start-End)*(Size/Work))/Time)/(Depth/33+1)
