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:

r

aw= 0.261 T= 23.8 'C H2O= 15 ppm

You can change the format of the output with the following commands:

- Outputting interval can be changed with the INTV command.
- Output message format can be changed with the FORM command.

Stop Measurement Output

Use the S command to end the RUN mode. After this command all other

commands can be used. You can also press the Esc button or reset the

transmitter to stop the outputting.

S

Since the interface is half-duplex, you must enter the command when the

transmitter is not outputting. Give the command again if the transmitter

continues to output measurement messages.

See SMODE command on page 33 to change the default (power-up)

operation mode.
