HM8118: Basic knowledge (ID #661)
In general, the LCR bridge HM8118 (as well as all other LCR meter in this price segment) is determined complex quantities, that means the impedance and phase angle of the connected component. These values are determined by measuring an AC current which is induced into the DUT. Based on the impedance (X-axis) and the phase angle (angle), the device can determine the missing value for the Y-axis. These values are frequency dependent.
