Autonomous Sampling (Logging)
Commands
(continued)
#iiStartDateTime=
mmddyyyyhhmmss
Set delayed logging start month, day, year,
hour, minute, second.
#iiStartLater
Start logging at time set with delayed start
date and time command. Data is stored in
FLASH memory. To change setup after
#iiStartLater
has been sent (but before
logging starts), send
#iiStop
, change setup
as desired, and then send #ii
StartLater
again. If communicating via USB, starts
sampling after USB cable removed AND
#iiStartDateTime=
reached.
#iiGetAvgRestart
Get and transmit
average
data, start next
averaging cycle, and (re)start logging in
(
#iiSampleInterval
/ 2) seconds. Cannot
be sent when communicating via USB.
#iiGetAvg
Get and transmit
average
data and start
next averaging cycle. Unlike
#iiGetAvgRestart
, this command does not
reset logging time base. Cannot be sent
when communicating via USB.
#iiSS
Get and transmit
raw
statistics
– number
of samples in average, and maximum,
minimum, delta, and average for
temperature, pressure, and pressure
temperature. Continue averaging. Cannot
be sent when communicating via USB.
Notes:
•
After receiving
#iiStartLater
, the
39
plus
-IM displays
not logging: waiting to
start at
in reply to
#iiDS
.
Once logging has started, the
#iiDS
reply shows
logging
.
•
If the delayed start time has
already passed when
#iiStartLater
is received, the
39
plus
-IM executes
#iiStartNow
.
•
If the delayed start date and time
is more than 90 days in the future
when
#iiStartLater
is received,
the 39
plus
-IM assumes that the
user made an error, and it
executes
#iiStartNow
.

Example:
Program 39
plus
-IM with ID=03 to start logging on
20 July 2016 12:00:00 (user input in bold).
#03STARTDATETIME=07202016120000
#03STARTLATER
Example:
Get statistics for 39
-plus
-IM with ID=03
#03ss
average count = 6
tmax = 1792564, tmin = 1786389, dt = 6175, avg = 1789490
pmax = 95976, pmin = 94947, dp = 1029, avg = 95340
ptmax = 23850, ptmin = 23850, dpt = 0, avg = 23850
Note:
#iiSS
resets when you stop and then
restart logging (i.e., it looks at data
from the current autonomous
sampling session). For example, if
you are logging and there are
25 samples in memory,
#iiSS
will
provide statistics for those
25 samples. If you then stop logging
and restart,
#iiSS
will ignore those
25 samples in its calculations.
