Serial Line Output Commands
Start Measurement Output
Use the R command to start the continuous outputting of measurement
values as an ASCII text string to the serial line. The format of the
measurement message is set with the FORM command.
R
Example (measurement message in default format):
r
Tdf= -2.5 'C H2O= 4919 ppm
Tdf= -2.5 'C H2O= 4918 ppm
Tdf= -2.5 'C H2O= 4917 ppm
…
Outputting the results continues in intervals issued with the command
INTV. You can stop the output by pressing the Esc key, or with the
command S. Since the interface is half-duplex, you must enter the
commands when the transmitter is not outputting.
Stop Measurement Output
You can stop the measurement output by pressing Esc, or with the S
command:
S
Set Output Interval
INTV [n xxx]
where
n = time interval = 0 ... 255
xxx = time unit = "S", "MIN", or "H"
Example:
intv 1 min
Output interval: 1 MIN
The shortest output interval (with n = 0) is approximately one second due
to the internal measurement cycle.
