Testing unit i.e. personal computer, for power switch for low voltages for protecting associated loads, has switch accelerated with current and/or transducer voltage, and graphical element displaying time passed during measurement

摘要

#CMT# #/CMT# The unit (PM) has a graphical display (1) displaying time-current characteristic curve and measured release times over associated current (I). The display displays time (t) over the associated current during measurement of the release times. A switch is accelerated with associated current (Ip) and/or with corresponding transducer voltage. A graphical element e.g. point, star or quadrate, displays the time passed during measurement of the release times. The graphical element is moved along a line for displaying the time on the display laterally over the latter associated current. #CMT#USE : #/CMT# Testing unit such as test device e.g. personal computer, for a switch i.e. power switch (all claimed) for low voltages for protecting associated loads. #CMT#ADVANTAGE : #/CMT# The graphical element e.g. point, star or quadrate, displays the time passed during measurement of the release times, thus displaying a process and result of measurement of the release times to the user, and hence ensuring that a user maintains direct impression over the lateral process of measurement. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical representation illustrating a testing unit in the form of a test device for a switch. t : Time I : Current Ip : Associated current PM : Testing unit 1 : Graphical display.
