12.3. Gases

The Teric has supports independent, 5 gas lists for OC 
Rec, OC Tec, and CC dive modes. 

Note that OC Tec mode and BO mode share the same 
gas list. Editing one will edit the other. 

This is the same as the Edit Gases item found in the 
main menu, but is conveniently located along with the 
other dive settings. 

For a description of how to appropriately set each 
gas, please see the Edit Gases section on page 59.

In CC/BO mode, both the CC diluent and BO open 
circuit gas lists are directly accessible, eliminating the 
need to toggle between the two operating modes to 
check gases from the Edit Gases option in the main 
menu. 

12.4. Set Points

This menu item is only available in CC/BO mode 

High & Low Set points

Like the Set Points selection in the main menu, this 
menu allows you to edit your High and Low set points. 

Auto Set Point switch

SP Auto Up

 and 

SP Auto Down

 are also available in 

this menu to set up automatic set point switching. 
They can be set up to auto switch up only, down only, 
both, or neither.

Use 

SP Auto Up

 to set whether the up switch occurs 

automatically or manually. 

If 

SP Auto Up

  is set to “On”, use 

Auto Up Depth

 set 

the depth at which the auto switch occurs. 

The menu options are the same for the down set point 
switch.

Example:

Up:

 

0.7 > 1.3 

= Auto, Up Depth = 70 ft.

Down:

  1.3 > 0.7 

= Auto, Down Depth = 41ft

The dives starts at the 0.7 set point. As you descend 
past 70ft, the set point switches “up” to 1.3. 

You finish your bottom time, then begin ascending. 
When you ascend above 41ft, it switches “down”  
to 0.7. 

When a switch is set to “Auto”, you can always 
manually override the setting at any time during the 
dive. 

The automatic switches only occur when crossing 
the specified depth. Say for example, the switch up 
depth is set to 50ft. You start the dive on the low set 
point, then as you descend past 50ft, the set point 
automatically switches up to high. If at say 80ft you 
then manually switch back to the low set point, the 
set point will remain low. If you ascend shallower 
than 50ft then re-descend deeper than 50ft again, 
the automatic set point switch will occur again. The 
Teric enforces a 20ft (6m) gap between switch up 
and switch down depths to prevent rapid automatic 
switching between set points for small depth changes. 
The values 0.7 and 1.3 are shown as examples only. 
Other values for the low and high set point can be 
adjusted in the Dive Setup menu.
