Auto Fire
If you select Auto Fire on the Water Sampler tab, and click Auto Fire
Pressures & Positions, the Auto-Fire Table Entry dialog box appears (to define
the closure order and closure pressures or depths):
Make the desired selections. Click OK.
Bottles may be closed in any order desired.
Enter pressures/depths in any order; when you
click OK SEASAVE reorders list from deepest to
shallowest (you can see reordered list by clicking
Auto-Fire Pressures & Positions again on
Water Sampler tab).
Upcast is enabled (has begun) when
pressure/depth exceeds this value. If CTD
never meets this criteria (i.e., CTD did not
go as deep as anticipated), no water
samples are taken.
Input values for each bottle
firing as pressures (db) or
depth (meters). Dialog box
text changes to correspond.
Salt water or Fresh water – used to calculate depth from
measured pressure if depth in meters is selected.
For salt water, algorithm estimates local gravity from latitude.
It uses latitude from NMEA navigation device, if NMEA is
enabled in .con file. If your system does not have NMEA,
enter desired latitude on Miscellaneous tab in
Configure Inputs.
For fresh water, algorithm ignores gravity variation with
latitude, because fresh water applications are usually
shallow, and effect of gravity variation is insignificant.
