特徴とする可変抵抗器用通電検査装置。 Voltage application means for applying a predetermined voltage across a resistive element to a variable resistor whose resistance value is varied according to the position of a slider slidingly displaced on the resistive element;
The voltage applied by this voltage applying means is taken as a reference voltage,
Comparing the voltage taken out from the slider,
A voltage comparator for detecting a maximum resistance value whose output voltage changes from a low level to an intermediate level before and after the variable resistor reaches its maximum resistance value; Almost the same voltage as the voltage taken out from the slider is used as the reference voltage, and the voltage taken out from the slider is compared in magnitude, and the output voltage changes from a low level to a high level before and after the variable resistor exceeds the standard resistance value. The output voltage difference between the voltage comparator for standard resistance value detection, this voltage comparator for standard resistance value detection, and the voltage comparator for maximum resistance value detection is the difference between the high and low levels or the difference between the high and medium levels. 1. An energization testing device for a variable resistor, comprising a display that displays which of the two levels is in two ways, with an approximately intermediate value between the two levels as a boundary.
