ABSTRACT:
The invented auto-ranging device has a signal measuring A/D converter, a range-switching A/D converter of a faster processing speed, a range-switching amplifier with variable amplification capabilities, and a processing controller which utilizes the variable amplification factors to alter the output signals from the switching A/D converter to generate signals appropriate for a scale range of a multi-range measuring A/D converter.
