Using the NiTek Trio

NiTek Trio Dive Computer User Manual v1.2 37

Gauge mode

Gauge mode is automatically entered when the computer enters the

water. It begins displaying depth and time once you descend below 4

feet (1.2 meters).

Gauge operation is when the NiTek Trio is operating simply as a depth

gauge and bottom timer. “Gage” and the dive-profile are displayed on

the screen, exposure to nitrogen and oxygen and no-decompression

limits are not tracked, and no bar graphs are displayed. This mode is

used by divers who are relying solely on dive tables for decompression

information. The operating depth limit when in gauge operation is 328

feet (100 meters).

Note: To enter and set up gauge mode, see “Using gauge mode.”

Note: If a dive has been made in gauge mode, the “Dive” mode can

not be chosen for 48 hours. You cannot select Gauge mode if the

computer determines there is still residual nitrogen from a previous

dive while in Dive mode, or if the surface interval has been less than 10

minutes.

While in gauge mode underwater, there are two screens you can toggle

between. The primary screen displays depth and time. The secondary

screen displays maximum depth and temperature.

Gage mode, primary and secondary screens

(1) Current depth: This is the current depth of the dive.

(2) Total dive time: This is the total time for the dive.

(3) Temperature: This is the lowest temperature reached on the dive.

(4) Max depth: This is the maximum depth reached during the dive.

Note: a maximum depth is not shown in this example, indicating the

diver is still descending.

To toggle between screens underwater:

1. Press and hold Set for 4-5 seconds.

The back light turns on, and the computer switches to the

secondary screen.

2. Release Set to return to the primary screen.
