What is the difference in the PO2 display when I have the external sensor switched on?
When diving with the VR3 in closed circuit mode with a link and the external sensor on, (XO2 ON), · the reading on the bottom line of your VR3’s dive screen is the actual PO2 for the gas you are breathing. · On the second line up you will see the diluent gas. · A short push of the left switch on the VR3 will show your internal PO2 set point on the second line up. · This will revert to the diluent gas display after 10 seconds. When diving with the VR3 in closed circuit mode with a link and the external sensor off, (XO2 OFF), · the bottom line of the VR3’s dive screen shows the internal set point, NOTE: unless the diluent PO2 is greater than set point, in which case the diluent PO2 is shown*(see example below). · The second line up shows the diluent gas. NOTE: This is the same as the display on non-link VR3s in CCR mode. Example: · you have your VR3 and Rebreather setpoint at a PO2 of 1.2. · You are diving with an air diluent at 55m · At 55m (6.5 ATA) with air as your diluent the PO2 of
