CALIBRATION DEVICE FOR RESISTANCE VALUE AND MEASUREMENT DEVICE RESISTANCE MEASURING FUNCTION USING BINARY-MULTIPLE RESISTANCE INCREASE, AND RESISTANCE CALIBRATION METHOD USING SAME

摘要

The present invention relates to a calibration device for a resistance value and a measurement device resistance measuring function using a binary-multiple resistance increase and to a resistance calibration method using same, the device and method being capable of adjusting a resistance value error of a target resistor by measuring the resistance value error of the target resistor through a resistance value of a reference resistor and adjust the error of the resistance measuring function of a measurement unit. The calibration device comprises: a reference resistor which has a reference set value; a pair of target resistors which have resistance values corresponding to the reference resistance, incrementally increases and have the same resistance value; a measurement unit which is connected to both ends of the reference resistor and the target resistor and measures resistance values of the reference resistor and the target resistor; a comparison unit which is connected to the measurement unit and compares a reference resistance measurement value measured from the reference resistor with the measurement value measured from the target resistor; a display unit which displays the reference resistance measurement value and the target resistance measurement value compared by the comparison unit; and a storage unit which stores the reference resistance measurement value and the target resistance measurement value displayed on the display unit.
