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

Polled Sampling Commands

These commands request a single sample. The 19plus V2 always stores data

for the most recent sample in its buffer. Some polled sampling commands also

store data in FLASH memory - the 19plus V2 will not execute the store data

in FLASH memory portion of those commands while logging data.

SL Output last sample from buffer (obtained

with polled sampling, or latest sample

from logging), and leave power on.

SLT Output last sample from buffer, then take

new sample and store data in buffer.

Leave power on. Data is not stored in

FLASH memory.

TS Take new sample, store data in buffer,

output data, and leave power on. Data is

not stored in FLASH memory.

TSS Take new sample, store data in buffer

and FLASH memory, output data, and

turn power off.

TSSOn Take new sample, store data in buffer

and FLASH memory, output data, and

leave power on.

GetLastSamples:x Output last x samples from FLASH

memory. If x is greater than the number of

samples in memory, 19plus V2 outputs all

samples in memory. If x is omitted,

19plus V2 outputs just the last sample.

You do not need to stop logging

(magnetic switch or Stop command)

before sending GetLastSamples:x.

Notes:

• The 19plus V2 has a buffer that

stores the most recent data

samples. Unlike data in the

FLASH memory, data in the

buffer is erased upon removal or

failure of power.

• Pump operation for polled

sampling is defined by

MooredPumpMode=, even if

your 19plus V2 is set to Profiling

Mode (MP). Thus, the 19plus V2

ignores the minimum conductivity

frequency (MinCondFreq=) and

pump delay (PumpDelay=) for

polled sampling.

• Leave power on in SL, SLT, TS,

and TSSOn descriptions refers to

power for the 19plus V2 as well

as for the pump and any auxiliary

sensors. Power remains on until

QS is sent or the instrument

times out (after 2 minutes).
