Lost gas handling

When the diver ascends to gas switch depth, a notification is raised, recommending the optimal gas. If the diver doesn’t switch in 2 minutes, the notification is repeated.
If the diver doesn’t switch to recommended gas in next 2 minutes, the gas is marked as “lost” and is no more used in plan calculation. Nevertheless the gas is still accessible and can be selected manually, the “lost” flag is cleared in such case. The ascend plan is recalculated at the moment the gas is marked as lost. The lost flag is visible in gas switch menu.

ppO2 limits

high ppO2 deco – used in CCR modes, in OC if degassing has already started (depth < decompresion zone start)
high ppO2 bottom – used in OC dives at bottom and start of ascent phase

Low button setting and stopwatch

Setup / Preferences / User interface / Stopw. btn. Options:

  • Disabled: stopwatch not available
  • Base scr.: low button handles stopwatch only if Detailed dive screen is selected.
  • Always: low button handles stopwatch in any dive screen.

Stopwatch is displayed in the Deep stop and Safety stop field on the Detailed screen.

  • First press: show stopwatch
  • Next press: toggles stopwatch on/off
  • Long press: stopwatch reset, either running or stopped.

If stopwatch is stopped for 20s, it disappears from the screen. Beware: If stopwatch button is active, all other functions are suppressed (screen off, brightness boost, gas selection shortcut, SP selection shortcut). Nevertheless if Base scr. setting is selected, original low button function remains unchanged in other dive screens. Screensaver setting remains active and if the screen is off, first press of any button switches display on.

Bailout GF handling

GF handling bound with mode change is now smarter.

  • Mode change any CCR -> OC, Bailout GF is selected
  • Mode change Measured CCR -> Fixed CCR, Bailout GF is selected
  • Mode change any mode -> Original CCR, Standard GF is selected GF manually switched to Bailout GF remains active until manually switched to Standard GF.

Voting logic

If there are 3 sensors connected, a voting logic applies to find and exclude bad sensor. Sensor can be disabled (by user) or excluded (by voting logic). If a sensor is excluded, the pO2 is still checked and an alarm is raised if pO2 is too high. Alarm may be suppressed by disabling the excluded sensor from menu. At least two sensors must be stable, and if the difference between sensors is too high, the most different or not stable one is excluded. If the excluded sensor value is back within the limit, it is returned to normal state, or it can be done manually.

Dive time termination

Setup / Preferences / Timeouts / Dive Time Auto setting: dive time stops on surface, jumps to current time if the dive continues Cave setting: dive time continues regardless of depth Warning: Dive termination setting remains active, if not set to zero.

Changes

Freedom version 1.13.2 Release notes

Changes

  • setup for Freedom acting as secondary monitor for CCR devices

Freedom as monitoring device

If Freedom is attached as parallel monitoring device, there could be a problem with sensor termination. Freedom contains its own terminating resistors, and this could interfere with terminators in some CCR devices, or isolation resitors in sensor fork device. If Freedom shows wrong voltage when connected to CCR device, use following setup:

New configuration items:

  • in main menu, “Setup / Rebreather / Sensor termination”
  • in sevice menu “Miscellaneous / 3rd sensor ratio”

Sensor termination (default On) allows to disconnect terminators inside Freedom for sensors 1 and 2. When set to Off, sensors 1 and 2 will show full sensor voltage. (Only sensors 1 and 2, limited by hardware)

3rd sensor ratio (default 1.00): It works as a virtual amplifier for sensor 3. Allowed values are 1.00 – 3.00. You have to adjust this ratio so Freedom shows the voltage as you can measure with Freedom disconnected.

IMPORTANT: this setting is active if terminators are off ONLY ! When terminators are On, 3rd sensor works without this coefficient!
