Disassembly:
- Clean out of old transducer wires into circuit board is a pain.  Try to
  remove old wires as cleanly as possible.  Use small soldering iron and 
  use its heat to push through hole and remove bits of wire that remain by 
  hand.

Replacing transducers (K-probe):
- Clean out RTV from channel along arms
- Clean out RTV and remove block at boom junction
- The path for the wire should now be easily accessible, rewire and reapply RTV

Replacing transducers (NUW):
- Prepare wire ends for both conductors, solder together to make a loop
- Use ~1m of white thread, tie one end through wire loop.  I use two
  overhand knot around both wires.
- GENTLY pull transducer out and thread in.
- Cut off old wire.
- Repeat wire preparation and thread tying on new transducer.
- EVEN MORE GENTLY pull new transducer wire through.  It will help to
  feed the transducer wire while pulling the thread.

Array Assembly (NUW):
- Most done using golf shafting epoxy, room temperature cure overnight.
  (vertical tubes silver-soldered)
- Clean all surfaces well, roughen smooth surfaces with file.
- Use circular jig to assemble transducer holders and cross pieces.  It is
  helpful to use the small plates with cross grooves to weight down and align.
- Use flat plate jig to assemble upper and lower arms to vertical tube.
  Pay attention to location of hole in center of vertical tube.
- Remeasure array geometry using Delrin balls and dial calipers (borrow from
  shop).  
  - The Delrin balls are a tight fit, it may be necessary to enlarge the hole
    (around the top opening only!) with a 5/16" (3/8"?) bit.
  - Measure all inside dimensions.
  - Process using:
    x <- fun.nuw.angles() [you will be prompted for distances]
    x [to print out angles -- ideally, 0 followed by 5 60s.]
    fun.nuw.matrix(x) [to calculate the matrix]
    (source in: /net/pam/isff/src/sfun/util/nuw.matrix.q)
  - Save output in a file like:
    /net/aster/doc/instruments/newuw/meas_2000 [I do this manually, editing
    the file and pasting in the values.]
- Type this matrix into the instrument using the "Z Z sonic" menu, option
  to enter new matrix.

Boom Assembly:
- Seal&Peel around transducer wires through block
- Seal&Peel inside vertical array tube
- Seal&Peel flange block to electronics housing
- RTV around back connector
- RTV fill inside back connector tube

General Inspection:
- Transducers should be solidly held in mounts with some RTV, with a small
  (~1mm) gap between the transducer housing and the array.  If not:
  - (Gently) pull out transducer until most of cork is showing, or wire stops
  - Put a small bead of RTV around the base on the cork
  - Push in all the way and clean up excess RTV
  - Pull out 1mm and let dry
- Transducer faces should not have an RTV separation from metal housing.
  If so, replace transducer (check with ATI first?).  At least, look at
  signal on the 'scope.
  (Am trying cleaning with alcohol, then forcing silicone grease (currently
  Dow 111) into cracks, wipe off face.)

Configuration:
- "Esc"ape to enter menu
- "E" to print current settings
- Since menus differ between revisions of software, these options are general,
  but should all be accessable from the "A", "B", and "Z" sub-menus:
  A Menu?
  - 9600 baud
  - parity OFF
  - ASCII output ON
  - Terse output ON
  - Output Cs OFF
  - Output Ts ON
  - Output Ws&Dir OFF
  B Menu?
  - Median filter OFF
  - Data quality check OFF
  - Shadow correction {ON for ATI K-probes connected to EVE;
                       OFF for NUW probes and K-probes connected to ADAMs}
  Z Menu
  - Output spike status ON
  - Max FD correction 0.80 {only used for ATI K-probes connected to EVE}
  - FD correction 0.20     {only used for ATI K-probes connected to EVE}
  ZZ Menu (entered from Z Menu by typing another "Z" and a password "SONIC")
  - ID set appropriately
  - Enable? {xxx for ATI K-probes (15 cm),
            yyy for NUW probes (20 cm),
  - Window {xxx for ATI K-probes (15 cm),
            yyy for NUW probes (20 cm),
  - Non orthogonal array {OFF for ATI K-probes
                          ON for NUW probes}
  - Non-orthogonal rotation matrix {can print, compare to sheet in box.
                                    However, since sheets in boxes sometimes
                                    get swapped, this is probably correct
                                    if it is reasonably close.  If not,
                                    reenter coefficients using menu command}

Calibrate:
- "Esc"ape to enter menu
- "D" to calibrate
- "Y"es you're sure
- Enter T (we're using the handheld Vaisala probe from the cal. lab)
- Enter RH (we're using the handheld Vaisala probe from the cal. lab)
- Put calibration chamber over path to be calibrated.  The white cardboard
  box tubes are best for the ATI K-probes, the blue foam box tube is the
  best for the NUW probes.
- Enter path (u, v, or w).  u=A, v=B, w=C for NUW probes.
- Note that the pathlength is approximately either 0.15 or 0.20 m and that
  the offset is close to zero (0.012 m/s typical)
- Repeat for other 3 paths.
