If not, repeat the calibration process. You may get a cell stuck message while
calibrating with the counterlungs full of oxygen. If so, you may need to add a breath
of air to the loop to allow auto calibration to take place.
Fill and evacuate the rebreather one more time with oxygen and the displays should
read 11.0 Bar PO2 +/- 0.1 PO2
Now try calibrating the VR again.
Closed Circuit Diving Operation
If you have purchased and installed the PIN to activate the VR's I/O connector, in the
Dive Options screen you will be able to move the highlight to the XFunc and XDec
features via successive short pushes of both switches.
To activate the VR for use with a rebreather link cable, with the highlight under
XFunc use short pushes of either switch to bring up XO2.
Then, with the highlight under XDec use a short push of either switch to bring up ON.
On the Dive Screen with XDec OFF the display shows SP followed by the VR's
internal set-point on the second line up. The diluent gas is displayed on the bottom
line.
Single sensor screen Triple sensor screen
(3 cells and average shown)
Note: if the partial pressure of oxygen in the diluent at the prevailing dive depth
exceeds the VR's internal set point, then the diluent PO2 will be displayed instead of
the set-point.
Large Triple PO2 Screen Saver
In the second DVo screen a screen saver can be a
ctivated with it’s turn on time. If set,
after the selected time period the VRx will display PO2 of each cell in large
characters. No other information will be shown on the dive display. A short push of
the right button will return the screen to the normal dive display.
If the screen saver appears on the surface, a short push on the right goes back to the
main display while a short push on the left goes to the cell raw Millivolt screen. When
the unit is exposed to air this is a useful tool to check cell health (confirm against the
cell manufacturers specifications).
