This procedure is for an ASIMET module that has either been newly manufactured, or repaired and calibrated, and should be performed regardless of whether the instrument is to be deployed on a VOS or in a stand-alone buoy application.

The following procedures are the minimum necessary GO - NOGO tests and final prep for an ASIMET instrument. ALWAYS do at least these tests before deploying an ASIMET instrument.

These tests can be performed with a bench power supply set to 13.5 volts.

1. Open the housing with a large flat blade screwdriver and remove the housing.

2. Setup per the ASIMET Module Operations document.

3. Power up the VMCM2 and verify the sign-on message.

4. Check that current consumption; The current for most modules should be 5ma to 9ma on start up and then reduce to 1 or 2 ma. WND has a start up current of 25ma and a run of 7ma to 11ma depending on whether a compass is installed.

5. Type #WND01A (or HRH for humidity, PRC for precipitation, etc). Watch the return: WND01 - Communications have been established.

6. Type #WND01H to get the help menu. Refer to the particular instrument's command set for further info (or the ASIMET website)

7. Type #WND01L to get the ID, SN, cal etc info.
   • For modules with standalone option (FLASH card and internal battery):

     - Check the time. Check the memory or "Records Used" = 0. If the records are not = 0 the flash card must be erased. If time is not accurate, it must be set. See steps below for setting time and erasing FLASH.

8. 11. Type #WND01T to go into the test mode. Check that the output is reasonable for the module being tested. Use <esc> to exit the test mode.

9. Type #WND01C to get the calibrated output return. Check that the output is reasonable for the module being tested. This also checks that the unit is out of the test mode and is collecting one minute data. Disconnect the power and computer from the module. Skip to Step 11 below

10. If you have a standalone module, you must also perform the next several steps:
    1. To erase the flash, type #WND01FE The return will prompt:
       Erase entire card? (Y/N)
       Type [Y], then watch for:
       Erasing Flash Card . . . . . . . . . .Cleared

    2. Set your watch or clock to accurate UTC. Type in a time a few seconds in advance of the actual time; i.e. at 14:25:00, type #WND01D2002/01/15 14:25:1 ---- DO NOT hit final digit yet. The time is entered when you hit the last digit. Wait until the time reaches 15 seconds and then hit the 5.

    3. Type #WND01L and note that the time when the L was entered matched the UTC on your watch. Also note that the "Records Used = 0".

    4. Remove the battery rail. Install a new battery with foam pads to insure a tight fit. Re-install the battery rail. Check that the MOLEX/AMPMOD battery adapter cable is installed on the P1 connector. (NOTE: If you are shipping the instrument, make sure the MOLEX is not connected to the battery.)

11. Re-install the housing. Check the o-rings. Connect the bottom connector to the end cap. Install the end cap using the large flat blade screwdriver. Install a dummy plug.

12. The module is ready to deploy (or ship with battery disconnected).
