Notes
Using the "CN:mm" command, the comparator limit values can be recalled.
The upper limit value recalled can be output using the "?HI" command.
The lower limit value recalled can be output using the "?LO" command.
The upper limit value can be changed using the "HI:" command.
The lower limit value can be changed using the "LO:" command.
"mm" indicates a two-digit numerical value 01 to 20, which corresponds to C01 - C20.
