4.6 Special Applications
4.61 Measurement of inductance under bias current conditions
Is usually measured directly. For inductive components that contain iron cores or cores, the result
may be different due to the nonlinear distortion of the core. To reduce the nonlinear distortion error, the
test level should be selected lower.
The bridge does not have the function of providing the inductor bias current. When the inductor bias
current is needed, it should be provided by an external circuit.
When designing an external circuit, it should be ensured that no DC voltage is applied to the bridge to
access the measurement terminal.

4.6.2 Capacitance Measurement under Applied Bias Voltage
The bridge does not have the function of providing voltage bias. When a capacitor bias is required, it
should be provided by an external circuit.
When designing an external circuit, it should be ensured that no DC voltage is applied to the bridge to
access the measurement terminal.
