Upon completion of the measurement, a service request “a” is sent to the data recorder
indicating the sensor data is ready. The recorder may wake the sensor with an SDI-12 BREAK
(continuous spacing by the data recorder on the data line for at least 12 ms) and collect the data
anytime after the service request is received, or when the specified processing time has elapsed.
Examples of “aMc!” commands:
Command Response Time Values Description
“aM!” “a0609” 60 s 9 Make one measurement from CB through CE.
“aM3!” “a0004” 0 s 4 Make a measurement of Cell 3 (if ProfilingMode=Yes).
Note: Report data taken at the time of the last “aM!”
command over the range set by the BC, CS, and NC
commands (see Note †† on page 102 regarding “aMn!”).
