The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

the time taken for a circuit or measuring device, when subjected to a change in input signal, to change its state by a specified fraction of its total response to that change.

The input range of a channel determines how large signals can be measured. The input range is defined as full scale value, the highest voltage that can be measured, both in positive as in negative direction.
