#iiOutputFormat=0: Raw Decimal Data
(for diagnostic use at Sea-Bird)
(if
#iiFormat=0
or

)
ii,ttttttt, ppppppp, vvvvv, dd mmm yyyy, hh:mm:ss
or
(if
#iiFormat=2
)
ii,ttttttt, ppppppp, vvvvv, hh:mm:ss, mm-dd- yyyy

-IM ID (0 – 99); sent only in response to

.
•
ttttttt = temperature A/D counts.
•
ppppppp = pressure sensor pressure A/D counts; sent only if pressure
sensor installed.
•
vvvvv = pressure sensor pressure temperature compensation A/D counts;
sent only if pressure sensor installed.
•
dd mmm yyyy = day, month (3-letter abbreviation), year.
•
mm-dd- yyyy = month (2-digits), day, year.
•
hh:mm:ss = hour, minute, second.
The ID and temperature are separated by a space; all other data is separated
with a comma and a space.
Notes:
•
Time is the time at the
start
of the
sample.
•
The pressure sensor is an absolute
sensor, so its
raw
output
(
#iiOutputFormat=0
) includes the
effect of atmospheric pressure
(14.7 psi). As shown on the
Calibration Sheet, Sea-Bird’s
calibration (and resulting calibration
coefficients) is in terms of psia.
However, when outputting pressure
in
engineering units
, the 39
plus
-IM
outputs pressure relative to the
ocean surface (i.e., at the surface the
output pressure is 0 decibars).
The 39
plus
-IM uses the following
equation to convert psia to decibars:
pressure (dbar) =
[pressure (psia) - 14.7] * 0.689476
Example:
Response to
!iiData
for 39
plus
-IM with
#iiOutputFormat=0
,
#iiFormat=0
, ID=03, pressure sensor installed:
03,1722523, 93818, 23833, 14 Jul 2016, 09:01:34
(ID, temperature counts, pressure sensor pressure counts, pressure sensor temperature compensation counts, date, time)
Note:
Sample number is never transmitted
if
#iiOutputFormat=0
, regardless of
the setting for
#iiTxSampleNum=
.
