Digital multimeter having improved recording functionality

摘要

The present invention relates, in a first aspect, to digital multimeters implementing a selective recording of the measured data using a recording component capable to compare the measured value with an upper recording threshold and a lower recording threshold. It also relates, in a second aspect, to digital multimeters implementing automatic capturing and saving by using an auto-save component capable to detect a stable measurement data and to automatically save the detected stable measurement data. A third aspect of the invention relates to digital multimeters managing the stored data by using an auto-incrementing descriptor component capable to assign descriptors to the saved data in order to easily handle them. The problem solved has to be regarded as how to manage the data saved in a digital multimeter. A fourth aspect of the invention relates to digital multimeters handling periods of inactivity by using an additional application processor capable to operate at a lower clock rate than the measurement clock rate in order to optimise the operating cycles.
