Abstract: An automatic range selection-type analog tester capable of automatically switching to the optimum measuring range even if the measurand of an object to be measured is undetermined. A range select signal generating circuit is designed to generate a range select signal for selecting one of a plurality of voltage dividers of a range selector circuit in such a manner that the divided voltage output of the object divided through the range selector circuit comes into a predetermined range and also a range display displays the corresponding measuring range in accordance with the range select signal.
