Input-related functions perform input-related processing. They also perform processing
for the two-input changeover mode, which uses two types of input to achieve wide-range
measurements.

".o" here denotes an odd channel
number , where "o" is 1 or 3. ".e"
here denotes an even channel
number, where "e" is 2 or 4. Only
channels 1 and 2, or 3 and 4 can be
combined.
