4.3.7 Do float self-test
4.4 Complete initial tests
Section 5 Laboratory tests
5.1 Test float bladder
1. Enter io to make sure that the air valve is open, then wait for 30 seconds.
2. Enter c several times to see the battery voltage, amps, and internal pressure values.
The initial internal pressure vac should be 82–88 counts at room temperature. This
value will change with temperature.
3. Enter ic to close the air valve.
4. Enter ii to start an inflation cycle.
In approximately 2 minutes, when the cycle is complete, the c> prompt shows. The
typical inflation cycle takes fewer that 55 pulses to reach 133 counts. If the float uses
more than 70 pulses, contact the manufacturer. If the float uses 128 pulses, the
bladder inflation sequence fails. Contact the manufacturer.
5. Enter c several times to see the inflated internal pressure, vac.
The internal pressure should be 130–135 counts. The goal is 133 counts.
6. Enter io to open the air valve.
Make sure that all configurations are compatible and that all tests are "pass."
Enter is to start the self-test.
Three warnings that may show, but are not an indication of any problem:
•
Warning: SBE 41cp FWRev violation: [5.3.5] != [5.3.3] or [5.3.4]. This firmware
change does not change how the 41N functions. This error will be corrected in the
next firmware version.
•
Warning: Unexpected LBT model: [9523B] != [9523] or [9522] (Sep 24 2019 04:04:29,
70452 sec) SelfTest(). Modem has been tested and approved for use, but the
firmware was not updated. This issue is fixed in the BGCi firmware but may still show
in ARGO floats.
•
Warning: Unexpected LBT firmware [DB17011] != [DB15005] or [TM12003]. Modem
has been tested and approved for use, but the firmware was not updated. This issue
is fixed in the BGCi firmware but may still show in ARGO floats.
Contact the manufacturer if any other warnings show.
The last step of the initial tests is to freeze the float.
1. Enter if, then y, then push Enter to freeze the float. The float cannot be deployed in
this state and should only be frozen between tests in the laboratory.
2. Disconnect from the float.
3. Stop Tera Term.
It is best if these tests are done before and after the float is shipped to its deployment
site, but if this is not possible, do lab tests approximately one month before the float is
shipped to its deployment site. If the float has been in the lab for over six months, the
manufacturer recommends that the user do the Initial Tests on the sensors. Refer to
Initial tests for float
on page 7 for details.
This test verifies that the air system operates correctly and can hold pressure for the
average time the float needs for telemetry.
1. Stand the float vertically in a climate-controlled room and let it adjust to the room
temperature (18–27 °C).
2. Connect to the float.
3. Start Tera Term or other terminal emulator program.
