Abstract:
An LCR meter to increase accuracy of balancing uses sub-balancing method, additional to analog balancing by trans-impedance amplifier (TIA). For this, the LCR meter, based on TIA, to correct analog auto-balancing, applies the inverted voltage equal to unbalanced voltage to noninverting input of the TIA. And only one measurement of voltages is needed for.
