SET Commands
Set commands are used to set instrument parameters and data
collection modes. You will use the Set Mode (SM) command to
control data collection.

SM is used to set the data collection mode and the sample interval.
At the end of each sample interval, the data are reported and, if in a
continuous mode, the data are cleared internally and the next
sample is started. The four available modes are shown in the list
below.

every sample interval. Concatenates “S” record to the “D” record.
