Abstract
PURPOSE: To make read of a display equipment easy and sure, by controlling the current value flowed to a measured resistance into a fixed value independently of the value of the measured resistance in the resistance measuring unit using clip- system transformers for injection and detection.
CONSTITUTION: Current Ix flowed to measured resistance Rx is controlled into a fixed value independently of the value of measured resistance Rx by the function of the system including clip-system current transformer CT, clip-system transformer PT, and integrator IG. Consequently, voltage ex generated across both ends of measured resistance Rx corresponds to the value of measured resistance Rx. This voltage ex is detected by coil 24 in transformer PT, and the detection voltage is rectified and amplified by rectifying and amplifying circuit RE2, and the value is displayed on display equipment DI. Thus, since the output of rectifying and amplifying circuit RE2 is proportional to the value of measured resistance Rx, the scale proportional to the value of the measured resistance is used when an indicator is used as the display equipment, so that read becomes easy and read error can be prevented.
