Software
Algorithm: The computer uses either the Bühlmann ZHL-16B model or the VPM-B model. Every computer can be set up
on one algorithm or the other, at the user’s discretion.
For RATIO iX3M Deep: Operating on level systems it is possible to set up the conservatism desired.
For RATIO iX3M Tech+ and iX3M Reb: Using the Bühlmann ZHL-16B algorithm there is the possibility of an exact choice
of the Gradient Factors. Using the VPM-B algorithm there is the possibility of an exact choice of the inert gases’ critical
bubble radius.
Software’s characteristics
ASM: Adaptive Sigmoidal Model: it optimises decompressive calculations in case of repetitive dives.
Extra Deep Stops: The computer expects the possibility to insert the Extra Deep Stops .
Violation control: it controls in a clever way the diver’s behaviour during his/her ascent and it advises him/her to use the
diving charts only if the decompressive algorithm is not valid anymore.
Disabling Violation control: it prevents that the RATIO iX3M gives up working weather or not the diver follows the
indications given by the device. (For expert divers only. The safety system inactivation is recorded in the Logbook).
