battery savings with the compromise that you often lose the first 200 ms of
a recording.
RECORD hh:mm:ss
Starts a new recording of the specified duration. If the RECORD command
is inside a repeat/until loop, the recording may end early to match the outer
loop ending time.
Before a RECORD command, your program must include one of each of
the following commands: HPF, GAIN, FS, ZC, and TRGLVL. It is not
necessary to repeat those commands before each RECORD command, but
you may if you wish to have different values in effect at each RECORD
command. In addition, at least one of the FS or ZC commands must have its
channels parameter set to a value other than OFF.
Recording files larger than 2.0 GB are divided into smaller segments.
PAUSE hh:mm:ss
Pauses the program for the specified amount of time. If you set the duration
of the PAUSE command to greater than 1 minute (3 minutes if using the
GPS option), the SM3BAT enters low-power sleep mode and wakes up at
the next scheduled recording.
AT DATE DDMMMYY
Causes the program to wait until the specified date. YY are the last two
digits of the year in the current century beginning with the year 2000.
NOTE: If you start the program after the specified AT DATE , the command is ignored
and the program continues.
AT TIME hh:mm:ss
Causes the program to wait until the specified date time.
NOTE: If you use an AT TIME, AT SRIS or At SSSET command and start the program
after that time of day, the recorder will assume you wish to record starting at the
previously occurring sunset, sunrise or time and begin recording immediately.
For example, if you have a program that starts with AT TIME 16:00:00 and you are in
the field starting the program at 17:00:00, the recorder will not wait until 16:00:00 the
next day, but instead will start recording immediately.
AT SRIS±hh:mm:ss
Causes the program to wait until sunrise, plus or minus the specified time.
