Manual revision 006 Section 4: Deploying and Operating SBE 19plus V2 SBE 19plus V2

Profiling Mode

The SBE 19plus V2 samples data at 4 Hz (one sample every 0.25 seconds),

averages the data at pre-programmed intervals, stores the averaged data in its

FLASH memory, and transmits the averaged data real-time. The 19plus V2

provides several methods for starting and stopping logging, depending on the

settings for IgnoreSwitch= and AutoRun=:

IgnoreSwitch= AutoRun=

To Start Logging:

To Stop Logging:

N N

Slide magnetic

switch on.

Slide magnetic switch off, or

send

Stop

Y N

Send StartNow, or

StartDateTime=

and

StartLater

Send Stop.

Y or N Y

Turn on external

power.

• Turn off external power, or

• (if you want to send

commands to check or

modify setup) Send

Stop.

Example: 19plus V2 in Profiling mode

Wake up 19plus V2. Set date and time to October 1, 2011 at 9:05 am. Initialize

logging to overwrite previous data in memory. Set up with 1 voltage sensor,

average every 4 samples, and output data in raw hex format. Set up with a 60-

second pump turn-on delay after pump enters water, to ensure pump is primed

before turning on. Set up to initiate logging with the magnetic switch. After all

parameters are entered, verify setup with status command. Send power-off

command.

(Click Connect in Seaterm232’s Communications menu to connect and wake up.)

DATETIME=10012011090500

INITLOGGING

VOLT0=Y

NAVG=4

OUTPUTFORMAT=0

PUMPDELAY=60

IGNORESWITCH=N

GETCD (to verify setup)

Start logging by putting magnetic switch in On position. Put 19plus V2 in water,

and allow to soak for at least time required for pump turn-on (PumpDelay=60)

before beginning downcast. If desired, use Seasave to view real-time data. When

cast is complete, stop logging by putting magnetic switch in Off position.

Upload data in memory, in format SBE Data Processing and Seasave can use.

Send power-off command.

(Click Connect in Seaterm232’s Communications menu to connect and wake up.)

(Click Upload– Seaterm232 leads you through screens to define data to be

uploaded and where to store it.)

Note:

Sea-Bird ships the 19plus V2

with AutoRun=N (it will not

automatically start sampling

when external power is

applied). If you send

AutoRun=Y:

• Send QS to put 19plus V2 in

quiescent (sleep) state, and

then turn power off and then

on again to start sampling.

•

Send StartNow to

start sampling.

Note:

Use Stop to:

• Stop sampling

• Stop waiting to start sampling (after

Startlater has been sent)

Once Stop is sent, the 19plus V2

accepts all commands again.
