Abstract:
A monitor for measuring or controlling power gain switching of a monitor, the monitor comprising:one or more sensors coupled with the electric circuit and operative to sense one or more power parameters in the electric circuit and generate one or more analog signals indicative of said power parameters; at least one analog to digital converter coupled with said sensors and operative to convert said analog signals to one or more digital samples; and at least one processor coupled with said analog to digital converter and operative to automatically select a gain channel defined by a predetermined electrical range from a plurality of gain channels based on samples of said gain channel having a bit count near a maximum bit count for said gain channel, without saturating said gain channel, said gain channel representing an input channel to be monitored; said at least one analog to digital converter sampling said plurality of gain channels simultaneously; wherein said processor uses samples from more than one of said plurality of gain channels to calculate power parameters.
