Smart dive computers
V
Gauge mode is provided for those who prefer to utilize their own tables (technical diving) or for those who
go freediving in addition to scuba diving.
Dives in gauge mode are performed at your own risk!
When in gauge mode, the Smart will only display time and depth information, however nitrogen tissue
loading and oxygen exposure will be calculated just as they would be during a regular SCUBA dive. It is
consequently very important that even when using the Smart in gauge mode, the correct value of your
oxygen percentage is set
-> 14.
Because the dive computer has residual nitrogen information after having been utilized in gauge mode, it
is ready for use as a regular computer at any time after switching it back to computer mode
.
Setting an incorrect mixture carries an inherent risk of decompression sickness
and/or oxygen toxicity! An incorrect gas mixture can be lethal!
Even before a dive in gauge mode, make sure that the set gas mixture cor
-
responds to the gas mixture currently used.
• If you are diving trimix or any mix other than oxygen/nitrogen with an oxygen
percentage of 21% or higher, input the correct percentage value for the oxy
-
gen. The computer will track oxygen exposure correctly and exaggerate the
nitrogen loading.
• If you are diving trimix or any mix with a percentage of oxygen lower than
21%, set the computer to 21% oxygen. The computer will exaggerate both
the oxygen exposure and the nitrogen loading.
Enabling the gauge mode (Switching back to the regular dive computer mode)
To use the Smart in gauge mode, you must first enable the computer via Smart
-
TRAK and the infrared interface.
Choose "Dive Computer Settings" under the "Options" pop-up window in
SmartTRAK. Once the "Dive Computer Settings" dialog box opens, the PC will
first "read" the existing settings in the dive computer. Click on "ON" ("OFF" to
switch back to the regular dive computer mode) under "Gauge Mode", then
click on the right icon in the top row to "write" the changes to the dive com

puter. The dive computer will now show "OnG" on the display.
