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.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
