Example:
8CC!
800205<CR><LF>
The sensor will have 5 measurements in 2 seconds.
“aR0!” Start Continuous Level Measurement
This command is used to request a continuous measurement
defined by “aXHn!” or Serial Command $DM
.
IMPORTANT:
The sensor must be in Auto-start continuous measurement mode (See aXCn! or serial
command $MA).

Example:
8R0!
8+14.029<CR><LF>
The measurement value is
“
+14.029
”.
“aR5!” Start Continuous Measurement for “Temperature”
This command is used to request a continuous

IMPORTANT:
The sensor
must be in Auto-start continuous measurement mode (See aXCn! or serial command $MA).
Command:
Example:
8R5!
8+37.3<CR><LF>
The temperature value is
“
+37.3 °C
”.
“aRCn!” Start Specified Continuous Measurement with CRC
These commands are used to request specified continuous measurements for the
defined by “aXHn!” or Serial
Command $DM
and temperature data and include the CRC.
IMPORTANT:
The sensor must be in Auto-start continuous measurement mode (See aXCn! or serial
command $MA).
