OPTION 10: AUTO-SETTING BATHY MANUAL VALUES WITH AUTO CALC'S
This option is available in SeaKing surface software V1.53 onwards.
The purpose of this feature is to automatically set the manually entered 'Manual' (sometimes called
'System') values for Density & Velocity of Sound with the Auto-updated values calculated from CT
Probe readings. The main benefit of this feature is to prevent (or counter) glitches that may occur
when CT readings momentarily drop out for any reason.
If CR readings dropout momentarily, the surface Bathy software will immediately switch from the
"Auto" Density and V.O.S. (calculated from CT) to the "Manual" Density and V.O.S. (entered in
Bathy Setup Form). If the Manual values are not close to the Auto-updated values then in the case
of the Density, this will cause "jump" in the Depth calculation.
If any "jumps" in Depth are encountered then it may be a case that the CT probe readings may
have been momentarily invalid for any reason; perhaps a blocked or faulty CT probe. In these
circumstances, enabling this feature will help counteract this.
In order to enable the "Auto-setting Manual values" feature, the user will need to edit the
C:\Windows\Sonv3so.ini file and move down through 4/5 of the file to find the following section…
;*****************************************************************
[BATHY1]
;; Bathy1 uses Normal, nominal 4Hz data rate settings in SONV3.CFG
.
.
;;Auto-update System Density/VOS with CT Auto values
;CTAUTOSYSTEM=-1
… Then change the last line above to the following (i.e. remove the ";" character)…
CTAUTOSYSTEM=-1
Save and exit the Sonv3so.ini file and re-run SONV3 where the new changes will immediately take
affect.
Note: This should only be performed when the Bathy is out of the water as closing down the
'SONV3' program during a dive will result in a reset of the Mean updated Density values.
