Freedom Closed Circuit
The Freedom closed circuit computer is the highest version of the Freedom decompression computers, which along with the function of the previously mentioned computers also includes the calculation of online decompression for CCR. Freedom can be connected to up to 3 oxygen sensors of your rebreather. For diluent, bailout and open circuit there are up to 9 gas mixtures available, including helium mixtures.
The Divesoft Freedom CCR can be connected to a rebreather with the included O2 sensor cable. One, two or three O2 sensors can be connected. The average pO2 value can be read on the primary screen and detailed information about each sensor, including sensor voltage, can be accessed via a separate screen. Fixed setpoint and SCR modes for different types of rebreathers are also available.
Please specify which version of the O2 cells connection cable you want to deliver with your computer:
Connecting cable for oxygen sensors (Molex)
Connecting cable for oxygen sensors for rEvo (Molex)
Connecting cable for oxygen sensors (Fischer)
up to 9 OC mixtures with any content of Oxygen and Helium
up to 8 diluents for CCR in addition to OC mixtures
Bühlmanns ZHL decompression algorithm
fully adjustable gradient factors
deco stops or deco ceiling for continual decompression
full color TFT display
five screens during the dive including the graphical dive profile
reversible display for left/right hand
durable aluminum body
300 m (1 000 ft) operational depth

Freedom displays are protected by protector display overlay.
You can choose from two variants of the fastening strap (35,5 cm or 42,5 cm).
You have to set sensor termination in your Freedom if you want to use it with the Connecting cable for oxygen sensors (Molex), please follow this procedure:
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 should show full sensor voltage.
(Only sensors 1 and 2, limited by hardware)
3rd sensor ratio (default 1.00): It works as 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!
