Special functions

Input range switching,
temperature fluctuation compensation enabling/disabling,
channel skip, scaling, special data offset,
peak-/bottom-hold, zero clip, zero shift, comparator,
averaging (time-specified, count-specified, moving average),
disconnection detection

Output range switching, output data offset,
scaling, error hold,
upper/lower limit alarm, output limit,
channel skip, output in PROG mode

*1 When the temperature fluctuation compensation is used, the temperature fluctuation compensation time of 80 µs will be added regardless of the number of channels being used.
