Function Open/Short Circuit Correction Open/short circuit correction function can effectively reduce the error of distributed parameter caused by the test lines,and help to improve the measurement accuracy. Data Recording Function In the reading hold mode,the maximum value,minimum value and average value can be dynamically obtained within a certain range,which is convenient to judge the dynamic data of the test value in real time. Function Electrolytic Capacitance Function The electrolytic capacitance function of the meter professionally measures electrolytic capacitor components with positive/negative electrodes,which can avoid capacitor damage caused by the measurement components when the positive/negative electrodes are unstable.
