Digital LED voltmeter
In this somewhat unusual digital voltmeter, the measurand (voltage to be measured) is digitized in an analogue-todigital (A-O) converter and then displayed in three decimal digits. The display is not the usual seven-segment type, but consists ofthree groups of ten LEOs. Although this type of display isa little unusual, themeasured valuecan beread withoutproblem after only a short familiarization period: even voltage changes can be readily interpreted. Note that the meter can only be used for measuring direct voltages.
