of sequence, the number of channels in the sequence, and the number of measurements to make on each channel in the sequence.
The mode determines the type of sequence to use. You can select among the
following modes.

For the four pre-defined sequences, the CHANNELS parameter sets the number of scanner channels, or in other words, the last scanner channel number in
the sequence. For the user defined sequence, CHANNELS sets the total number
of steps in the sequence. After the thermometer measures the last channel, the
sequence repeats starting again at the beginning.
The NUMBER OF SAMPLES parameter specifies the number of measurements to make on each channel before advancing to the next.
The scanner sequence mode works with either of the sampling modes described
in Section 7.2. If continuous sampling is selected, the channels will sequence
indefinitely. If SAMPLE N is selected, the channels will be sequenced until the
total number of measurements reaches the number specified with SAMPLE N.
